Abstract
Owing to the lack of selection and limited intelligence in mechanical picking, some immature tomatoes that contain alkaloids are thrown away. Tomatine alkaloids are steroidal alkaloids naturally present in Solanaceae plants, which are distributed in small amounts in immature tomato fruits and decrease as the fruits ripen. Tomato glycoalkaloids are harmful to human health. However, in small quantities, there is some evidence that these compounds might be beneficial, as other non-antioxidant bioactivities. This article considers recent research on the biological effects of tomato glycoalkaloids in immature tomatoes, providing reference value for the potential development of these compounds.

Abstract
Steroidal glycoalkaloids (SGAs) are major plant defense metabolites against pests, while they are considered poisonous in food. The genetic basis that guides negative selection of SGAs production during tomato domestication remains poorly understood. Here, we identify a distal enhancer, GAME Enhancer 1 (GE1), as the key regulator of SGAs metabolism in tomato. GE1 recruits MYC2-GAME9 transcriptional complex to regulate the expression of GAME cluster genes via the formation of chromatin loops located in the neighboring DNA region. A naturally occurring GE176 allelic variant is found to be more active in stimulating GAME expression. We show that the weaker GE1 allele has been the main driver for selecting reduced SGAs levels during tomato domestication. Unravelling the "TFs-Enhancer-Promoter" regulatory mechanism operating in SGAs metabolism opens unprecedented prospects for SGAs manipulation in Solanaceae via precision breeding strategies.

Abstract
The intercellular space or apoplast constitutes the main interface in plant-pathogen interactions. Apoplastic subtilisin-like proteases-subtilases-may play an important role in defence and they have been identified as targets of pathogen-secreted effector proteins. Here, we characterise the role of the Solanaceae-specific P69 subtilase family in the interaction between tomato and the vascular bacterial wilt pathogen Ralstonia solanacearum. R. solanacearum infection post-translationally activated several tomato P69s. Among them, P69D was exclusively activated in tomato plants resistant to R. solanacearum. In vitro experiments showed that P69D activation by prodomain removal occurred in an autocatalytic and intramolecular reaction that does not rely on the residue upstream of the processing site. Importantly P69D-deficient tomato plants were more susceptible to bacterial wilt and transient expression of P69B, D and G in Nicotiana benthamiana limited proliferation of R. solanacearum. Our study demonstrates that P69s have conserved features but diverse functions in tomato and that P69D is involved in resistance to R. solanacearum but not to other vascular pathogens like Fusarium oxysporum.

Abstract
Nuclear factor Y (NF-Y) gene family is an important transcription factor composed of three subfamilies of NF-YA, NF-YB and NF-YC, which is involved in plant growth, development and stress response. In this study, 63 tobacco NF-Y genes (NtNF-Ys) were identified in Nicotiana tabacum L., including 17 NtNF-YAs, 30 NtNF-YBs and 16 NtNF-YCs. Phylogenetic analysis revealed ten pairs of orthologues from tomato and tobacco and 25 pairs of paralogues from tobacco. The gene structure of NtNF-YAs exhibited similarities, whereas the gene structure of NtNF-YBs and NtNF-YCs displayed significant differences. The NtNF-Ys of the same subfamily exhibited a consistent distribution of motifs and protein 3D structure. The protein interaction network revealed that NtNF-YC12 and NtNF-YC5 exhibited the highest connectivity. Many cis-acting elements related to light, stress and hormone response were found in the promoter of NtNF-Ys. Transcriptome analysis showed that more than half of the NtNF-Y genes were expressed in all tissues, and NtNF-YB9/B14/B15/B16/B17/B29 were specifically expressed in roots. A total of 15, 12, 5, and 6 NtNF-Y genes were found to respond to cold, drought, salt, and alkali stresses, respectively. The results of this study will lay a foundation for further study of NF-Y genes in tobacco and other Solanaceae plants.

Abstract
Crop-pollinator interactions are essential for world food security. Studying crop pollination from a network approach allows identification of target pollinators for conservation and management, and gaps in our knowledge. Solanaceae represents the third highest ranked family based on economic value, and its production is highly improved by animal pollination. This study aimed to integrate global data on solanaceous crop pollination and analyse the interaction patterns using a meta-network approach. Our questions were: (i) how are interactions structured and what are the structuring roles of species; and (ii) what are the main gaps in our knowledge? Data were obtained through a systematic review of the main scientific databases. The network structure was described using connectivity and modularity calculations, and the role of species using centrality metrics. The 251 pollinator species reported were in seven orders, mainly Hymenoptera (84.9%). The generalists Bombus and Apis species were the most common pollinators. The meta-network was modular, and all modules mostly included bees. Most species were peripherals, around 12% were connectors, and there were no module hubs. Apis mellifera was the only network hub (supergeneralist). The most important pollinators are the most managed pollinators worldwide; however, many native species play a role in structuring the meta-network. Main gaps include species of importance to pepper pollination, lack of species-specific identification, and the need for more robust experimental studies evaluating the pollination efficiency of native, manageable bees.

Abstract
Hydrochar from agricultural wastes is regarded as a prospective and low-cost material to activate peroxymonosulfate (PMS) for degrading pollutants. Herein, a novel in-situ N-doped hydrochar composite (RHCM4) was synthesized using montmorillonite and waste reed straw rich in nitrogen as pyrolysis catalyst and carbon source, respectively. The fabricated RHCM4 possessed excellent PMS activation performance for decomposing quinclorac (QC), a refractory herbicide, with a high removal efficiency of 100.0% and mineralization efficiency of 75.1%. The quenching experiments and electron spin resonance (ESR) detection disclosed free radicals (•OH, •SO4-, and •O2-) and non-radicals (1O2) took part in the QC degradation process. Additionally, the catalytic mechanisms were analyzed in depth with the aid of various characterizations. Moreover, the QC degradation intermediates and pathways were clarified by density functional theory calculations and HPLC-MS. Importantly, phytotoxicity experiments showed that RHCM4/PMS could efficaciously mitigate the injury of QC to Solanaceae crops (pepper, tomato, and tobacco). These findings give a new idea for enhancing the catalytic activity of hydrochar from agricultural wastes and broaden its application in the field of agricultural environment.

Abstract
Some plant species of the genus Cestrum L. (Solanaceae family) are known to cause poisoning in farming animals in Brazil, negatively affecting the livestock sector. In this context, this study aimed to carry out a systematic review of the Cestrum species that cause poisoning in ruminants in Brazil and to list the main phytochemicals involved in these toxic activities that have already been identified. Scientific documents were retrieved in Google Scholar, PubMed®, ScienceDirect®, and SciELO databases. After applying the inclusion criteria, a total of 38 articles published between 1920 and 2023 were included in the present study. Cestrum axillare Vell. [Syn. Cestrum laevigatum Schltdl.], Cestrum corymbosum Schltdl., Cestrum intermedium Sendtn., and Cestrum parqui L'Hér. were found to have reported cases of poisoning in the Northeast, Southeast, and South of Brazil. Natural poisonings in ruminants caused by these species have been recorded in ten Brazilian states, mostly in Rio de Janeiro, Santa Catarina, Rio Grande do Sul, and Pernambuco. In general, Cestrum species cause liver damage and a clinical-pathological state characterized by acute liver failure of the poisoned animals. Cattle are more susceptible to poisoning by these plants, but there are reports of poisoning by C. axillare in goats and buffaloes as well. Several chemical constituents were identified in C. axillare and C. parqui, including some saponins and terpenoids that may be associated with the cases of poisoning. However, only one chemical compound has been identified in C. intermedium, and no phytochemical investigation has been carried out regarding toxic compounds in C. corymbosum. It is expected that future studies fill the gap in determining the toxic principles present in these species.

Abstract
Vassobia breviflora belongs to the Solanaceae family, possessing biological activity against tumor cells and is a promising alternative for therapy. The aim of this investigation was to determine the phytochemical properties V. breviflora using ESI-ToF-MS. The cytotoxic effects of this extract were examined in B16-F10 melanoma cells and the relationship if any to purinergic signaling was involved. The antioxidant activity of total phenols, (2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) was analyzed, as well as production of reactive oxygen species (ROS) and nitric oxide (NO) was determined. Genotoxicity was assessed by DNA damage assay. Subsequently, the structural bioactive compounds were docked against purinoceptors P2X7 and P2Y1 receptors. The bioactive compounds found in V. breviflora were N-methyl-(2S,4 R)-trans-4-hydroxy-L-proline, calystegine B, 12-O-benzoyl- tenacigenin A and bungoside B. In vitro cytotoxicity was demonstrated at concentration ranges of 0.1-10 mg/ml, and plasmid DNA breaks only at the concentration of 10 mg/ml. V. breviflora extracts affected hydrolysis by ectoenzymes, such as ectonucleoside triphosphate diphosphohydrolase (E-NTPDase) and ectoadenosine deaminase (E-ADA) which control levels of degradation and formation of nucleosides and nucleotides. In the presence of substrates ATP, ADP, AMP and adenosine, the activities of E-NTPDase, 5´-NT or E-ADA were significantly modulated by V. breviflora. N-methyl-(2S,4 R)-trans-4-hydroxy-L-proline presented higher binding affinity (according to receptor-ligand complex estimated binding affinity as evidenced by ∆G values) to bind to both P2X7 and P2Y1purinergic receptors.Our results suggest a putative interaction of V. breviflora bioactive compounds with growth inhibitory potential in B16-F10 melanoma and suggest that may be considered as promising compounds in melanoma and cancer treatment.

Abstract
Adult T-cell leukemia/lymphoma (ATL) is a malignancy of mature peripheral T-lymphocytes caused by human T-cell leukemia virus type I (HTLV-I). There are an estimated 5-20 million HTLV-1-infected individuals worldwide. Conventional chemotherapeutic regimens used against other malignant lymphomas have been administered to patients with ATL, but the therapeutic outcomes of acute and lymphoma-type ATL remain extremely poor. In the course of our screening program for novel chemotherapeutic candidate compounds from plants against two human T-cell leukemia virus I-infected T-cell lines (MT-1 and MT-2), we screened 16 extracts obtained from different parts of 7 Solanaceae plants. We identified that the extracts of Physalis pruinosa and P. philadelphica showed potent anti-proliferative activity in MT-1 and MT-2 cells. In our previous study, we have isolated withanolides from extract of aerial parts of P. pruinosa and examined their structure-activity relationships. In addition, we are also investigating further structure-activity relationships about other withanolides from Solanaceae plants (Withania somnifera, Withania coagulans, Physalis angulate, Nicandra physalodes, Petunia hybrida, and Solanum cilistum). In this study, we attempted to isolate their active compounds against MT-1 and MT-2 from extracts of P. philadelphica. We identified 13 withanolides, including six newly isolated compounds [24R, 25S-4β, 16β, 20R-trihydroxy-1-oxowitha-2-en-5β, 6 β -epoxy-22,26-olide (1), 4β, 7β,20R-trihydroxy-1-oxowitha-2-en-5β, 6β -epoxy-22,26-olide (2), 17β,20 S-dihydroxywithanone (3), 2,3-dihydro-3β-methoxy-23β-hydroxywithaphysacarpin (4), 3-O-(4-rhamnosyl)glucosyl-physalolactone B (5), and 17R, 20R, 22S, 23S, 24R, 25R-4β, 5α, 6β, 20β, 22α -tetrahydroxy-16β, 23-diepoxy-1-oxowitha-2-en-26, 23-olide (6)], from the extract and examined the structure-activity relationships. The 50% effective concentration of withaphysacarpin (compound 7) [MT-1: 0.10 µM and MT-2: 0.04 µM] was comparable to that of etoposide [MT-1: 0.08 µM and MT-2: 0.07 µM]. Therefore, withanolides might be promising candidates for the treatment of ATL.

Abstract
Tomato severe rugose virus (ToSRV) is one of Brazil's main begomoviruses infecting tomato (Solanum lycopersicum). Recent studies indicate that soybean (Glycine max) crops harboring the whitefly Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) may have epidemiological significance by acting as an asymptomatic amplifier host for the virus. In this study, we gathered experimental greenhouse and field evidence of the role of soybean in the epidemiology of the disease caused by ToSRV. Tomato and Nicandra physalodes, known as good sources of inoculum of this begomovirus, were used as references. The infection rates of soybean, tomato, and N. physalodes with ToSRV in greenhouse no-choice transmission tests with B. tabaci MEAM1 were 50, 71.4, and 64.2%, respectively. The transmission efficiencies of ToSRV to tomato when B. tabaci MEAM1 acquired the virus in ToSRV-infected soybean, tomato, and N. physalodes were 43, 33, and 20%, respectively. Leaves of ToSRV-infected soybean, tomato, and N. physalodes used as sources of inoculum had similar virus titers. In the host preference assay, viruliferous whiteflies preferred to land on tomato rather than soybean and N. physalodes, whereas aviruliferous whiteflies landed indistinctly on these plants. Under experimental field conditions, the transmission efficiency of ToSRV to tomato was higher when tomato was used as a source of inoculum, followed by N. physalodes and soybean. Considering that soybean is extensively cultivated in several Brazilian states that also grow tomato, it can serve as an efficient asymptomatic source of inoculum and support the recent hypothesis that it can also play, under certain conditions, a relevant role as an amplifier host in the epidemiology of the disease caused by ToSRV.

Abstract
Vassobia breviflora (Sendtn.) Hunz is a plant of the Solanaceae family from South America and there are no apparent studies reported on the biological activity of the hexane extract. The aim of this investigation was to conduct phytochemical analyses using ESI-TOF-MS, while antioxidant activities were evaluated by the following methods 1,1-diphenyl-2-picrylhydrazyl (DPPH) 2,2"-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) radical capture (ABTS), ferric reducing antioxidant power (FRAP), total antioxidant capacity (TAC), and total oxidant status (TOS). Antimicrobial activities were performed by determining the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and antibiofilm formed. Cytotoxicity was measured by MTT and dsDNA PicoGreen tests, beyond the production of reactive oxygen species (ROS) determined by Dichlorodihydrofluorescein diacetate (DCFH-DA). The hexane extract showed the presence of 5 (choline, pantothenic acid, calystegine B, lanciphodylactone I, and 15"-cis-zeaxanthin) compounds detected. V. breviflora extract demonstrated reliable results utilizing different antioxidant methods. In antibacterial activity, V. breviflora extract exhibited inhibitory, bactericidal, and antibiofilm action in biofilm-forming bacteria. The hexane extract exhibited cytotoxicity against melanoma, lung cancer, glioblastoma, leukemia, uterine colon, and hepatocarcinoma tumor cells. In addition, all tested strains resulted in increased production of ROS. This plant extract may be considered in future as an alternative for development of new therapeutic options aimed at the treatment of diverse pathologies.

Abstract
Since the global COVID-19 pandemic began, the scientific community has dedicated efforts to finding effective antiviral drugs to treat or minimize the effects caused by the SARS-CoV-2 coronavirus. Some targets can act as inhibitor substrates, highlighting the Main Protease (Mpro), which plays an essential role in the translation and transcription of the virus cycle. Withanolides, a class of natural C28 steroidal lactones, are compounds of interest as possible inhibitors of Mpro and other critical targets of the virus, such as papain-like protease. In this study, the isolation of a new withanolide (1), along with the known 27-deoxywithaferin A (2) and 27-deoxy-2,3-dihydrowithaferin A (3), from the leaves of Athenaea velutina (Solanaceae) is described. Their structures were determined using spectroscopic and spectrometric methods (NMR, IR, HRESIMS). Moreover, the interaction and the stability of withanolides 1-3 and withanolide D (4), previously isolated of Acnistus arborescens, against the Mpro target through molecular docking, molecular dynamics, and binding free energy simulations were analyzed. The molecular dynamics results indicated that the complexes formed by the molecular docking simulations between the Mpro target with each of the withanolides 1-4 exhibited good stability during the simulations due to a slight change in the structure of complexes. The binding free energy results suggested that withanolide (1) can be a natural candidate against COVID-19 disease.Communicated by Ramaswamy H. Sarma.

Abstract
The mycoparasite Pythium oligandrum is a nonpathogenic oomycete that can boost plant immune responses. Elicitins are microbe-associated molecular patterns (MAMPs) specifically produced by oomycetes that activate plant defense. Here, we identified a novel elicitin, PoEli8, from P. oligandrum that exhibits immunity-inducing activity in plants. In vitro-purified PoEli8 induced strong innate immune responses and enhanced resistance to the oomycete pathogen Phytophthora capsici in Solanaceae plants, including Nicotiana benthamiana, tomato, and pepper. Cell death and reactive oxygen species (ROS) accumulation triggered by the PoEli8 protein were dependent on the plant coreceptors receptor-like kinases (RLKs) BAK1 and SOBIR1. Furthermore, REli from N. benthamiana, a cell surface receptor-like protein (RLP) was implicated in the perception of PoEli8 in N. benthamiana. These results indicate the potential value of PoEli8 as a bioactive formula to protect Solanaceae plants against Phytophthora.

Abstract
Cancer and infectious diseases are among the leading causes of death in the world. Despite the diverse array of treatments available, challenges posed by resistance, side effects, high costs, and inaccessibility persist. In the Solanaceae plant family, few studies with Vassobia breviflora species relating to biological activity are known, but promising results have emerged. The phytochemicals present in the ethyl acetate fraction were obtained using ESI-MS-QTOF, and the antioxidants assays 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) radical capture (ABTS), plasma ferric reduction capacity (FRAP), and total antioxidant capacity (TAC). Cytotoxic activity was evaluated by MTT, Neutral Red, and lactate dehydrogenase (LDH) released. The production of reactive oxygen species, nitric oxide, and purinergic enzymes was also investigated. Antibacterial activity was measured through minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and antibiofilm activity, in addition to genotoxicity in plasmid DNA. Five major masses were identified D-glucopyranose II, allyl disulfide, γ-lactones, pharbilignoside, and one mass was not identified. V. breviflora exhibited relevant antioxidant and cytotoxic activity against the HeLa cell line and enhanced expression effect in modulation of purinergic signaling. Antibacterial activities in the assays in 7 ATCC strains and 8 multidrug-resistant clinical isolates were found. V. breviflora blocked biofilm formation in producing bacteria at the highest concentrations tested. However, there was no plasmid DNA cleavage at the concentrations tested. Data demonstrated that V. breviflora exhibited an antioxidant effect through several methods and proved to be a promising therapeutic alternative for use against tumor cells via purinergic signaling and multidrug-resistant microorganisms, presenting an anti-biofilm effect.

Abstract
CONTEXT Solanaceae glycoalkaloids (SGAs) possess cardiomodulatory activity. OBJECTIVE This study investigated the potential interaction between verapamil and glycoalkaloids. MATERIAL AND METHODS The cardioactivity of verapamil and glycoalkaloids (α-solanine and α-chaconine) was tested in adult beetle (Tenebrio molitor) myocardium in vitro using microdensitometric methods. The myocardium was treated with pure substances and mixtures of verapamil and glycoalkaloids for 9 min with saline as a control. Two experimental variants were used: simultaneous application of verapamil and glycoalkaloids or preincubation of the myocardium with one of the compounds followed by perfusion with a verapamil solution. We used 9 × 10-6-5 × 10-5 M and 10-9-10-5 M concentration for verapamil and glycoalkaloids, respectively. RESULTS Verapamil, α-solanine and α-chaconine showed cardioinhibitory activity with IC50 values equal to 1.69 × 10-5, 1.88 × 10-7 and 7.48 × 10-7 M, respectively. When the glycoalkaloids were applied simultaneously with verapamil, an antagonistic effect was observed with a decrease in the maximal inhibitory effect and prolongation of t50 and the recovery time characteristic of verapamil. We also confirmed the expression of two transcript forms of the gene that encodes the α1 subunit of L-type calcium channels in the myocardium and brain with equal transcription levels of both forms in the myocardium and significant domination of the shorter form in the brain of the insect species tested. DISCUSSION AND CONCLUSIONS The results show that attention to the composition of the daily diet during therapy with various drugs is particularly important. In subsequent studies, the nature of interaction between verapamil and SGAs on the molecular level should be checked, and whether this interaction decreases the efficiency of cardiovascular therapy with verapamil in humans.

Abstract
PREMISE Plant defenses are shaped by many factors, including herbivory, lifespan, and mating system. Predictions about plant defense and resistance are often based on resource allocation trade-offs with plant growth and reproduction. Additionally, two types of plant resistance, constitutive and induced resistance, are predicted to be evolutionary alternatives or redundant strategies. Given the variety of plant trait combinations and non-mutually exclusive predictions, examining resistance strategies in related species with different combinations of growth and reproductive traits is important to tease apart roles of plant traits and evolutionary history on plant resistance. METHODS Phylogenetic comparative methods were used to examine the potentially interacting influences of life history (annual/perennial), mating system (self-compatible/self-incompatible), and species growth rates on constitutive resistance and inducibility (additional resistance following damage) across Physalis species (Solanaceae). RESULTS Resistance was evolutionarily labile, and there was no correlation between constitutive resistance and inducibility. Annual species with fast growth rates displayed higher constitutive resistance, but growth rate did not affect constitutive resistance in perennials. In contrast, inducibility was negatively associated with species growth rate regardless of life history or mating system. CONCLUSIONS The different effects of plant life history and growth rate on constitutive resistance and inducibility indicate that defensive evolution is unconstrained by a trade-off between resistance types. The interactions among plant life history, growth, and herbivore resistance show that plant defense is shaped not only by herbivore environment, but also by plant traits that reflect a plant's evolutionary history and local selective pressures.

Abstract
Antifungal assay-guided fractionation of the methanolic crude extract of Cestrum nocturnum (Solanaceae), popular known as ‘lady of the night’, led the isolation and identification of the steroidal saponin named pennogenin tetraglycoside, which was identified for the first time in this plant species by spectroscopic means. The crude extract, fractions and pennogenin tetraglycoside exhibited mycelial growth inhibition of Fusarium solani and F. kuroshium. F. solani is a cosmopolitan fungal phytopathogen that affects several economically important crops. However, we highlight the antifungal activity displayed by pennogenin tetraglycoside against F. kuroshium, since it is the first plant natural product identified as active for this phytopathogen. This fungus along with its insect symbiont known as Kuroshio shot hole borer (Euwallacea kuroshio) are the causal agents of the plant disease Fusarium dieback that affects more than 300 plant species including avocado (Persea americana) among others of ecological relevance. Scanning electron microscopy showed morphological alterations of the fungal hyphae after exposure with the active fractions and 12 phenolic compounds were also identified by mass spectrometry dereplication as part of potential active molecules present in C. nocturnum leaves.

Abstract
Chemical investigation of the alkaloid extract of the aerial parts of Schizanthus tricolor led to the targeted isolation of 26 hygroline derivatives of which 20 were fully characterized. They have not yet been described in the literature and their structures were established by 1D and 2D NMR, UV and IR spectroscopy, and HRESIMS. The configuration was determined by Gauge-Independent Atomic Orbital NMR chemical shift calculations supported by the advanced statistical method DP4 plus, vibrational circular dichroism, and measurement of optical rotation. Their anti-trypanosomatid, antiplasmodial and cytotoxic activities were measured. Several compounds exhibited low micromolar activity against Plasmodium falciparum. None of the identified molecules was cytotoxic.

Abstract
In a co-evolutionary crosstalk amid plants and their pollinators, nectaries serve as a labile link between the relatively fixed structural domains of divergent flower forms and associated pollination syndromes. Floral nectary plays a crucial role in sexual plant reproduction by enabling interaction between plants and their pollinators. It is known to associate with different floral whorls, and exhibits variations in structure and location in different clades across angiosperms. To infer evolutionary patterns, it is important to map key features associated with the trait at various taxonomic ranks. In the present study, we analysed variability and distribution of floral nectaries in Solanaceae for the first time. Floral nectaries of 23 taxa representing different clades in the family were studied using bright-field and scanning electron microscopy. The study reveals that although floral nectaries share anatomical similarity, they differ in morphology, composition within cells, and locations within a flower across the clades. The analysis suggests that (i) there is a shift from symmetric, lobed type nectary in the early branching sub-families to asymmetric, annular type in the late branching ones, (ii) floral organization has shifted from asymmetry (zygomorphy) to symmetry (actinomorphy) in corolla, and (iii) the lobed nectary correlates with zygomorphic floral forms that are pollinated by birds and long-tongued vectors, while the annular nectary is predominant among species with bee-pollinated actinomorphic flowers.

Abstract
Knowledge about Solanaceae species naturally adapted to salinity is scarce, despite the fact that a considerable number of Solanaceae has been reported growing in saline environments. Lycium humile Phil. inhabits extreme saline soils in the Altiplano-Puna region (Central Andes, South America) and represents a promising experimental model to study salt tolerance in Solanaceae plants. Seeds, leaves and roots were collected from a saline environment (Salar del Diablo, Argentina). Seeds were scarified and 30 days after germination salt treatments were applied by adding NaCl salt pulses (up to 750 or 1000 mM). Different growth parameters were evaluated, and leaf spectral reflectance, endogenous phytohormone levels, antioxidant capacity, proline and elemental content, and morpho-anatomical characteristics in L. humile under salinity were analyzed both in controlled and natural conditions. The multiple salt tolerance mechanisms found in this species are mainly the accumulation of the phytohormone abscisic acid, the increase of the antioxidant capacity and proline content, together with the development of a large leaf water-storage parenchyma that allows Na+ accumulation and an efficient osmotic adjustment. Lycium humile is probably one of the most salt-tolerant Solanaceae species in the world, and, in controlled conditions, can effectively grow at high NaCl concentrations (at least, up to 750 mM NaCl) but also, in the absence of salts in the medium. Therefore, we propose that natural distribution of L. humile is more related to water availability, as a limiting factor of growth in Altiplano-Puna saline habitats, than to high salt concentrations in the soils.

Abstract
Anticholinergic plants of the family Solanaceae have a long history of use as medicines, poisons, and recreational drugs. Though they were the intoxicating substances of choice throughout Europe for centuries, their use for these purposes has declined with the globalisation of other recreational drugs. The present study sought to examine the level of knowledge surrounding these plants among individuals who had used other hallucinogenic plants or mushrooms in Slovenia. Participants were questioned in regards to the anticholinergic Solanaceae that are known to grow wild in Slovenia: Atropa belladonna L., Datura stramonium L., Hyoscyamus niger L., and Scopolia carniolica L. As expected, only a small number of individuals had any substantial knowledge of these plants, and fewer still had used them; some were even unfamiliar with any of these plants. Knowledge of toxicity generally arose from family members, while books and the internet played prominent roles in regards to use knowledge. Knowledge of the plants was vastly varied, with many individuals confusing the plants for others, especially other members of the Solanaceae. Ultimately, a small group of individuals had the largest body of knowledge of these plants, though this was linked with university studies rather than traditional uses. Knowledge of the intoxicating Solanaceae has been largely lost in Slovenia among users of other botanical hallucinogens, likely due to the various dangers their use poses and the undesirable effects they often cause.

Abstract
The pollen micro-morphology of family Solanaceae from the different phytogeographical region of Pakistan has been assessed. In this study, thirteen species belonging to ten genera of Solanaceae have been studied using light and scanning electron microscopy for both qualitative and quantitative features. Solanaceae is a eurypalynous family and a significant variation was observed in pollen size, shape, polarity and exine sculpturing. Examined plant species includes, Brugmansia suaveolens, Capsicum annuum, Cestrum parqui, Datura innoxia, Solanum lycopersicum, Nicotiana plumbaginifolia, Petunia hybrida, Physalis minima, Solanum americanum, Solanum erianthum, Solanum melongena, Solanum surattense and Withania somnifera. The prominent pollen type is tricolporate and shed as a monad. High pollen fertility reflects that observed taxa are well-known in the study area. Based on the observed pollen traits a taxonomic key was developed for the accurate and quick identification of species. Principal Component Analysis was performed that shows some morphological features are the main characters in the identification. Cluster Analysis was performed that separate the plant species in a cluster. The findings highlight the importance of Palyno-morphological features in the characterization and identification of Solanaceous taxa. It is concluded that both LM and SEM significantly play a key role in correct identification of taxa studied.

Abstract
The endangered butterfly Scada karschina delicata Talbot, 1932 (Nymphalidae: Danainae: Ithomiini) is endemic to northeastern Brazil, occurring in very few forest remnants of the 'Pernambuco Center of Endemism'. Larvae feed on Solanaceae and are very similar to those of other species in the subtribe Mechanitina, with lateral projections on body, one of the main synapomorphies of this subtribe. Based on molecular data, S. k. delicata clustered together with S. karschina karschina, as a monophyletic group sister to the amazon clade of S. reckia. Based on all available data, S. k. delicata is known from only five localities of mid- to high-altitude forests (from 500 to 1000 m of altitude) in northeastern Brazil. Grounded on available data, a new assessment of extinction risk is proposed, and S. k. delicata is now considered Vulnerable (VU) taxon.

Abstract
Some medicinal plants of the Solanaceae produce pharmaceutical tropane alkaloids (TAs), such as hyoscyamine and scopolamine. Littorine is a key biosynthetic intermediate in the hyoscyamine and scopolamine biosynthetic pathways. However, the mechanism underlying littorine formation from the precursors phenyllactate and tropine is not completely understood. Here, we report the elucidation of littorine biosynthesis through a functional genomics approach and functional identification of two novel biosynthesis genes that encode phenyllactate UDP-glycosyltransferase (UGT1) and littorine synthase (LS). UGT1 and LS are highly and specifically expressed in Atropa belladonna secondary roots. Suppression of either UGT1 or LS disrupted the biosynthesis of littorine and its TA derivatives (hyoscyamine and scopolamine). Purified His-tagged UGT1 catalysed phenyllactate glycosylation to form phenyllactylglucose. UGT1 and LS co-expression in tobacco leaves led to littorine synthesis if tropine and phenyllactate were added. This identification of UGT1 and LS provides the missing link in littorine biosynthesis. The results pave the way for producing hyoscyamine and scopolamine for medical use by metabolic engineering or synthetic biology.

Abstract
Bacillus thuringiensis (Bt) toxins constitute effective, environmentally safe biopesticides. Nevertheless, insects' tolerance to Bt is influenced by environmental factors affecting immunity. To understand larval immune response in the devastating coleopteran insect pest Colorado potato beetle (CPB), we undertook a proteomic analysis of hemolymph of non-treated control larvae and larvae consuming non-lethal doses of spore-crystal mixtures containing the coleopteran-active Cry3Aa toxin. Results revealed lower amount of proteins involved in insect growth and higher amount of immune response-related proteins in challenged insects, sustaining the larval weight loss observed. Additionally, we found a potential regulatory role of the evolutionary conserved miR-8 in the insect's immune response relying on antimicrobial peptides (AMPs) production. Upon toxin challenge, different patterns of hemolymph AMPs expression and phenoloxidase activity were observed in CPB larvae reared on different Solanaceae plants. This suggests that diet and diet-associated insect midgut microbiota might modulate this insects' tolerance to non-lethal doses of Bt.

Abstract
Acylsugars are insecticidal plant specialized metabolites produced in the Solanaceae (nightshade family). Despite having simple constituents, these compounds are unusually structurally diverse. Their structural variations in phylogenetically closely related species enable comparative biochemical approaches to understand acylsugar biosynthesis and pathway diversification. Thus far, varied enzyme classes contributing to their synthesis were characterized in cultivated and wild tomatoes, including from core metabolism - isopropylmalate synthase (Leu) and invertase (carbon) - and a group of evolutionarily related BAHD acyltransferases known as acylsucrose acyltransferases. Gene duplication and neofunctionalization of these enzymes drove acylsugar diversification both within and beyond tomato. The broad set of evolutionary mechanisms underlying acylsugar diversity in Solanaceae make this metabolic network an exemplar for detailed understanding of the evolution of metabolic form and function.

Abstract
Laboratory and field studies were conducted with nymphs and adults of the Neotropical stink bug Runibia perspicua (F.) to evaluate their biology on plants. Total nymph mortality was ca. 13% on immature fruits of Brunfelsia australis Benth. (IFBA) and 90% on raw shelled peanuts, Arachis hypogaea L. (RSP); no nymphs survived on immature pods of green bean, Phaseolus vulgaris L., or on immature fruits of privet, Ligustrum lucidum Ait. Nymph developmental time was ca. 36 on IFBA and 55 days on RSP. Body weight was significantly greater when nymphs were raised isolated compared to those raised in groups. Adult feeding activity was greater than third instars on IFBA. Adult longevity on IFBA + cherry tomato, Solanum lycopersicum L. fruit, reached ca. 150 days. On IFBA, fecundity was 2.5 egg masses/female and 48.3 eggs/female; 25.6% of the eggs hatched. Adults did not reproduce on tomato. Body weight gain did not increase significantly for both sexes during the first four weeks of adult life on IFBA. In the field, plants of B. australis were surveyed in Passo Fundo, RS (28°15'S; 52°24'W). The majority of egg masses were deposited on the lower (abaxial) surface of leaves. Nymphs aggregated on immature fruits, and adults were seldom found on the plants. These are the first data on the performance of R. perspicua on B. australis indicating that this plant species is suitable to the bug's biology.

Abstract
The aim of this study was to detect ecotoxicological effects of 0.1 μm polystyrene microbeads in marine organisms belonging to different trophic levels. MP build up, lethal and sub-lethal responses were investigated in the bacterium Vibrio anguillarum (culturability), in the green microalga Dunaliella tertiolecta (growth inhibition), in the rotifer Brachionus plicatilis (mortality and swimming speed alteration) and in the sea urchin Paracentrotus lividus (immobility and swimming speed alteration) exposed to a wide range of microplastic (MP) concentrations (from 0.001 to 10 mg L-1). Survival was not affected in all organisms up to 10 mg L-1, while algal growth inhibition, rotifer and sea urchin larvae swimming behaviour alterations were observed after exposure to MPs. Ingestion was only observed in rotifers and it was directly correlated with sub-lethal effects. These results account for the ecotoxicological risk associated to the polystyrene microbeads, which are able to affect different endpoints in primary producers and consumers (rotifers and sea urchins) since no effects were observed in decomposers. This study points out the importance of using a battery of marine organisms belonging to different trophic levels by studying acute toxicity of MPs at low and high contamination levels, and investigating sub-lethal responses. Further investigations aimed at studying the transfer of these materials through the web are particularly recommended.

Abstract
Divergence in phenotypic traits often contributes to premating isolation between lineages, but could also promote isolation at postmating stages. Phenotypic differences could directly result in mechanical isolation or hybrids with maladapted traits; alternatively, when alleles controlling these trait differences pleiotropically affect other components of development, differentiation could indirectly produce genetic incompatibilities in hybrids. Here, we determined the strength of nine postmating and intrinsic postzygotic reproductive barriers among 10 species of Jaltomata (Solanaceae), including species with highly divergent floral traits. To evaluate the relative importance of floral trait diversification for the strength of these postmating barriers, we assessed their relationship to floral divergence, genetic distance, geographical context, and ecological differences, using conventional tests and a new linear-mixed modeling approach. Despite close evolutionary relationships, all species pairs showed moderate to strong isolation. Nonetheless, floral trait divergence was not a consistent predictor of the strength of isolation; instead this was best explained by genetic distance, although we found evidence for mechanical isolation in one species, and a positive relationship between floral trait divergence and fruit set isolation across species pairs. Overall, our data indicate that intrinsic postzygotic isolation is more strongly associated with genome-wide genetic differentiation, rather than floral divergence.

Abstract
Escouflaire antiasthmatic cigarettes and powders knew certain success during almost one century. The medical use of solanaceae with bronchodilator properties helped relieve numerous asthmatics. The Belgian pharmacist Charles Adolphe Escouflaire (1857-1909), pharmacist from the university of Leuven, Belgium, awarded his diploma in 1879. He created his antiasthmatic products in his pharmacy of Ath and established in 1885 a pharmaceutical laboratory. He registered trademarks under the brand name Zematone for its antiasthmatic cigarettes. His products will be rapidly known and sold all over the world. The discovery of a complete box of medical cigarettes in the Czech Republic allows us to evoke his products, the distributor F. S chnöbling in this country, the modes of display and uses. This article redraws the history of the laboratory under the direction of three generations of the Escouflaire family. The laboratory will expand after WWII with production factories in Baisieux and Blandain before definitely close in 1974.

Abstract
The infusion of Brugmansia suaveolens, popularly known as trombeteira or cartucheira, has been used to treat pain in Brazil. The present study was conducted to test for its antinociceptive effects using the abdominal-writhing, formalin, tail-flick, and hot-plate tests in mice. The aqueous extract from B. suaveolens flowers administered intraperitoneally at doses of 100 and 300 mg/kg body weight significantly inhibited acetic acid-induced abdominal constrictions. An increase in hot-plate latency was also observed in animals receiving both doses (100 and 300 mg/kg). In the formalin test, both doses from the aqueous extract inhibited the first (0-5 min) and second phase (20-25 min). Tail-flick assays demonstrated that treatment of animals with plant extract induced attenuation of the response. These results suggest that the aqueous extract from B. suaveolens flowers produced antinociceptive effects, as demonstrated in the experimental models of nociception in mice. This supports popular medicinal uses of this plant as an analgesic.

Abstract
Treehoppers (Membracidae) exhibit different levels of sociality, from solitary to presocial. Although they are one of the best biological systems to study the evolution of maternal care in insects, information on the biology of species in this group is scarce. This work describes the biology and ecology of Alchisme grossa (Fairmaire) (Hemiptera: Membracidae) in a rain cloud forest of Bolivia. This subsocial membracid utilizes two host-plant species, Brugmansia suaveolens (Humb. & Bonpl. ex Wild) Bercht. & J.Presl and Solanum ursinum (Rusby) (both Solanaceae), the first one being used during the whole year and the second one almost exclusively during the wet season. The development of A. grossa from egg to adult occurred on the plant where eggs were laid. Maternal care was observed during the complete nymphal development, and involved behavioral traits such as food facilitation and antidepredatory defense. Life cycle was longer on B. suaveolens during the dry season and shorter on S. ursinum during the wet season. Mortality was similar on both host plants during the wet season but was lower on B. suaveolens during the dry season. The presence of a secondary female companion to the egg-guarding female individual and occasional iteropary is also reported.

Abstract
In the last two decades the subtropical red tomato spider mite, Tetranychus evansi, has expanded its geographical distribution and emerged as a major invasive agricultural pest. The mite is considered to be native to South America. Since its first report from north-eastern Brazil in 1952, it has been reported from different continents. This paper reviews literature on several aspects of the biology of T. evansi related to its status as an invasive species. It addresses taxonomical issues, occurrences, life history traits, host-plant interactions, genetic diversity of geographical isolates and worldwide colonisation pathways. It also presents updated data which allowed the assessment of the actual worldwide distribution of this species, from its discovery to the latest reports. As T. evansi is considered an emerging agricultural pest, we also present data based on modelling of the potential of T. evansi to colonize new geographical areas. In addition, this review presents past and current research on natural enemies of T. evansi potentially useful for its biological control. While summarizing the knowledge on T. evansi, the review emphasizes research possibilities that are worth pursuing, mainly concerning the ability of T. evansi to establish new populations and to detect new promising natural enemies.

Abstract
The Bedes form one of the largest tribal or indigenous communities in Bangladesh and are popularly known as the boat people or water gypsies because of their preference for living in boats. They travel almost throughout the whole year by boats on the numerous waterways of Bangladesh and earn their livelihood by selling sundry items, performing jugglery acts, catching snakes, and treating village people by the various riversides with their traditional medicinal formulations. Life is hard for the community, and both men and women toil day long. As a result of their strenuous lifestyle, they suffer from various types of pain, and have developed an assortment of formulations for treatment of pain in different parts of the body. Pain is the most common reason for physician consultation in all parts of the world including Bangladesh. Although a number of drugs are available to treat pain, including non-steroidal, steroidal, and narcotic drugs, such drugs usually have side-effects like causing bleeding in the stomach over prolonged use (as in the case of rheumatic pain), or can be addictive. Moreover, pain arising from causes like rheumatism has no proper treatment in allopathic medicine. It was the objective of the present study to document the formulations used by the Bede traditional practitioners for pain treatment, for they claim to have used these formulations over centuries with success. Surveys were conducted among a large Bede community, who reside in boats on the Bangshi River by Porabari village of Savar area in Dhaka district of Bangladesh. Interviews of 30 traditional practitioners were conducted with the help of a semi-structured questionnaire and the guided field-walk method. It was observed that the Bede practitioners used 53 formulations for treatment of various types of pain, the main ingredient of all formulations being medicinal plants. Out of the 53 formulations, 25 were for treatment of rheumatic pain, either exclusively, or along with other types of body pain. A total of 65 plants belonging to 39 families were used in the formulations. The Fabaceae family provided 7 plants followed by the Solanaceae family with 4 plants. 47 out of the 53 formulations were used topically, 5 formulations were orally administered, and 1 formulation had both topical and oral uses. 8 formulations for treatment of rheumatic pain contained Calotropis gigantea, suggesting that the plant has strong potential for further scientific studies leading to discovery of novel efficacious compounds for rheumatic pain treatment.

Abstract
Hyoscine has been isolated as the main alkaloid from the leaves, flowers, pericarp and seeds of Datura cornigera Hook. Noratropine occurs in the leaves, flowers and pericarp. The following alkaloids have been obtained from the roots, (—)-3α,6β-ditigloyloxytropane, 7-hydroxy-3,6-ditigloyloxytropane, hyoscine, hyoscyamine, atropine, norhyoscyamine, noratropine, 3α,6β-dihydroxytropane and the presence of others indicated. Hyoscyamine is the principal alkaloid of the whole roots but the root-wood, although giving a low yield of total alkaloids, contains a relatively high proportion of noratropine.

Abstract
BACKGROUND The aim of this study was to examine consumption of fruit and vegetables in relation to tooth loss and income. METHODS Data were collected in 2004-06, using a three-stage, stratified clustered sample, involving a computer-assisted telephone interview (CATI), oral examination and mailed questionnaire followed by a food frequency questionnaire. RESULTS A total of 14 123 adults responded to the CATI (49% response) of whom 5505 (44% of those interviewed) agreed to undergo an oral epidemiological examination. In the nutrition sub-study, a total of n = 1218 persons were approached in New South Wales and Queensland, with n = 1129 responding (92.7% response rate). Among respondents aged 55 years or more 34.5% had <21 teeth. Adjusting for income the prevalence of infrequent consumption ('never or less than once a month') was associated with [PR = prevalence ratio (95% CI)] fewer teeth for the fruits, 'peach, nectarine, plum, apricot' PR = 1.91 (1.12, 3.25) and 'grapes or berries' PR = 1.69 (1.03, 2.76), and for the vegetables 'stir-fried or mixed' PR = 2.34 (1.14, 4.78), 'sweetcorn' PR = 1.45 (1.001, 2.10), 'mushrooms' PR = 1.62 (1.05, 2.50), 'lettuce' PR = 3.99 (1.31, 12.17) and 'soy beans' PR = 1.11 (1.01, 1.21). CONCLUSIONS An inadequate dentition was associated with lower consumption of a range of fruits and vegetables indicating that dentition-related impairment of chewing ability could have adverse consequences on nutritional intake among Australian adults.

Abstract
Initial screening of 14 Solanum dulcamara accessions enabled the identification of individuals resistant and susceptible to Phytophthora infestans. Crosses between contrasting genotypes resulted in three F(2)-BC(1) populations segregating for resistance to late blight in a laboratory assay and under field conditions. Genetic profiling of one of these populations using 128 AFLP primers generated three markers linked to the resistant phenotype. Blast analysis of the sequenced markers resulted in a plausible gene position on the distal end of the long arm of chromosome 9 that could be confirmed by CAPS markers. Thus, we describe a first resistant gene, named Rpi-dlc1, from S. dulcamara, a Solanum species native to Europe. In addition, one population was tested for broadness of resistance responses using a set of seven additional P. infestans isolates, varying in virulence. This indicated the possible presence of additional Rpi genes.

Abstract
Effects of Hyoscyamus niger L on central nervous system have been known for many years. The effects of methanolic extract of H. niger L. on seizures induced by picrotoxin was studied in mice in this investigation. In this study 7 groups of animals pretreated with methanolic extract of the plant (12.5, 25, 50, 100, 200, 300, 400 mg/kg/i.p.), 20 minutes prior to the picrotoxin (12 mg/kg/ i.p.)--induced seizures. Control mice received phenobarbital (40 mg/kg/i.p.) as positive control, or saline (10 ml/kg) as negative control. The latency of seizure (sec), duration of seizure (sec) and mortality rate were determined in test and control groups. The results of this study showed that latency of seizure was increased in groups that were pretreated with doses of 100, 200, 300 and 400 mg/kg of extract. In addition, methanolic extract of H. niger L. delayed the death time in mice as compared to control that was significant with doses of 200, 300 and 400 mg/kg. The most effective dose of extract was 300 mg/kg in this investigation (P<0.01). In conclusion, the results showed that methanolic extract of H. niger L. posses the anticonvulsant activity against picrotoxin-induced seizures in mice. The exact mechanism(s) by which the plant exerts its anticonvulsant activity is not determined yet.

Abstract
BACKGROUND AND AIMS Beginning in the last two decades of the 14th century, richly illuminated versions of the Tacuinum Sanitatis, the Latin translation of an 11th-century Arabic manuscript known as Taqwim al-Sihha bi al-Ashab al-Sitta, were produced in northern Italy. These illustrated manuscripts provide a window on late medieval life in that region by containing some 200 full-page illustrations, many of which vividly depict the harvest of vegetables, fruits, flowers, grains, aromatics and medicinal plants. Our objective was to search for and identify the images of taxa of Cucurbitaceae and Solanaceae. METHODS We have located all reported illustrated Tacuinum Sanitatis and similar or related manuscripts, searched through printed or electronic reproductions of them, categorized six of them that display full-page illustrations as archetypic, and established the identity of the Cucurbitaceae and Solanaceae appearing in these six manuscripts. KEY RESULTS AND CONCLUSIONS Of the Cucurbitaceae, Cucumis sativus (short-fruited cucumbers), Cucumis melo (including round as well as elongate melons), Citrullus lanatus (both sweet watermelons and citrons), and Lagenaria siceraria (including bottle-shaped as well as long gourds), are illustrated. Of the Solanaceae, Solanum melongena (egg-shaped purple aubergines) and Mandragora sp. (mandrake) are illustrated. These depictions include some of the earliest known images of cucumber, casaba melon (Cucumis melo Inodorous Group) and aubergine, each of which closely resembles an extant cultivar-group or market type. Overall, the botanically most accurate images are in the version of the Tacuinum located in the Osterreichische Nationalbibliothek, Vienna, cod. ser. n. 2644. Similarities and differences in botanical accuracy among the images of Cucurbitaceae and Solanaceae in the six archetypal Tacuinum manuscripts suggest to us that another illustrated Tacuinum, now lost, may have antedated and served as a model or inspiration for the six surviving archetypic manuscripts.

Abstract
The presence of volunteer potato Solanum tuberosum L., cutleaf nightshade, S. triflorum N., and hairy nightshade, S. physalifolium Rusby (Solanales: Solanaceae), throughout potato crop rotations can diminish the effectiveness of crop rotations designed to control disease and pest problems associated with growing potatoes. In greenhouse bioassays, larvae of the Colorado potato beetle, Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae) were placed in population densities of 0, 5, 10, and 40 per potato (cv. Russet Burbank) plant and 0, 5, 10, and 15 per cutleaf nightshade and hairy nightshade plant. Plants were treated with different rates of herbicides including fluroxypyr, prometryn, and mesotrione rates, and the physiological response on the potato plants was assessed by weighing shoot biomass 14 days after treatment. Consistently, across all bioassays, rate response functions were shifted as L. decemlineata density increased, such that less herbicide was required to achieve control. For instance, the herbicide rate needed to achieve 90% reduction in potato biomass was reduced from 62 to 0 g fluroxypyr per hectare and 711 to 0 g prometryn per hectare as L. decemlineata density was increased to 40 larvae per plant. Herbivory at higher L. decemlineata population densities and herbicides above certain rates resulted in large reductions in cutleaf and hairy nightshade biomass. Differences in rate response functions among L. decemlineata population densities indicated that L. decemlineata contributed to weed suppression in combination with herbicides. These data suggest that integrated weed management systems targeting volunteer potato, cutleaf nightshade, and hairy nightshade can be more effective when herbicide applications are combined with herbivory by naturally occurring Colorado potato beetles.

Abstract
The antioxidant activity of the crude n-hexane, dichloromethane, and methanol extracts from 25 species belonging to the Asteraceae, Euphorbiaceae, Rubiaceae, and Solanaceae families collected at natural reserves from the Eje Cafetero Ecorregión Colombia, were evaluated by using the spectrophotometric 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging method. The strongest antioxidant activities were showed by the methanol and dichloromethane extracts from the Euphorbiaceae, Alchornea coelophylla (IC50 41.14 mg/l) and Acalypha platyphilla (IC50 111.99 mg/l), respectively. These two species had stronger DPPH radical scavenging activities than hydroquinone (IC50 151.19 mg/l), the positive control. The potential use of Colombian flora for their antioxidant activities is discussed.

Abstract
Iresine herbstii Hook. (Amaranthaceae) and Brugmansia arborea (L.) Lagerheim (Solanaceae) are used in the northern Peruvian Andes for magic-therapeutical purposes. The traditional healers use Iresine herbstii with the ritual aim to expel bad spirits from the body. Furthermore, Iresine herbstii was used in association with other plants, such as Trichocereus pachanoi Britt. et Rose, for divination, to diagnose diseases, and to take possession of another identity. Also, species of Brugmansia have been reported to be used during ritual practices for magical and curative purposes. Given the above evidence, the aim of the present study is to evaluate if the central effects of Iresine herbstii and Brugmansia arborea could be associated with interaction with SNC receptors. Two Iresine herbstii extracts (methanolic and aqueous) and one Brugmansia arborea aqueous extract were tested for in vitro affinity on 5-HT(1A), 5-HT(2A), 5-HT(2C), D1, D2, alpha(1), and alpha(2) receptors by radioligand binding assays. The biological materials for binding assay (cerebral cortex) were taken from male Sprague-Dawley rats. The extracts affinity for receptors is definite as inhibition percentage of radioligand/receptor binding and measured as the radioactivity of remaining complex radioligand/receptor. The data obtained for Iresine extracts have shown a low affinity for the 5-HT(1A) receptor and no affinity for 5-HT(2A) receptor. Otherwise the methanolic extract showed affinity for 5-HT(2C) receptor (IC(50): 34.78 microg/ml) and for D1 receptor (IC(50): 19.63 microg/ml), instead the Iresine aqueous extract displayed a lower affinity for D1 (48.3% at the maximum concentration tested) and a higher value of affinity for D2 receptors (IC(50): 32.08 microg/ml). The Brugmansia aqueous extract displayed affinity for D1 receptors (IC(50): 17.68 microg/ml), D2 receptors (IC(50): 15.95 microg/ml) and weak affinity for the serotoninergic receptors. None of the three extracts showed relevant affinity to the alpha(1), and alpha(2) receptors. The results of our experiments indicate that Iresine herbstii methanolic extract was able to interact with the central 5-HT(2C) and D1 receptors and Iresine herbstii aqueous extract showed affinity for D2 receptors, thus confirming their ritual use. Instead Brugmansia arborea was able to interact only with the central dopamine receptors tested. Parallel studies are currently in progress for evaluating the extracts affinity and active components towards these and other receptor types (GABAergic).

Abstract
Tetranychus evansi Baker & Pritchard is an important pest of Solanaceae in several countries. Introduced accidentally to Africa, it presently occurs in many countries of that continent. In some of them, it is considered a key pest. The suspected area of origin of this mite is South America. The objective of the present study was to identify phytoseiid mites on solanaceous plants in association with T. evansi in south and southeast Brazil for introduction in the African continent for use in a classic biological control program. Almost 1,400 predatory mites of the family Phytoseiidae were collected, on 22 solanaceous species. The Amblyseiinae were the most diverse group in this study. Twenty-three of the species found belong to this subfamily, while only three belong to the Typhlodrominae and two to the Phytoseiinae. The most abundant and most frequent phytoseiid species were Phytoseius guianensis De Leon and Galendromus annectens (De Leon) of the Phytoseiinae and Typhlodrominae, respectively. The most frequent and abundant species of Amblyseiinae was Neoseiulus tunus (De Leon). Phytoseius guianensis and N. tunus were never found in association with T. evansi and G. annectens was found only once in association with it. Two factors suggested Phytoseiulus longipes Evans as the most promising predator found in this study. It could walk very well on tomato leaves infested by T. evansi, without being hampered by the profuse webbing produced by the prey and by the trichomes. In addition, several specimens of both sexes including eggs and nymphs of the predator were found associated with T. evansi on three different plant species and in two different periods of the year, when T. evansi was the only arthropod present on the leaves.

Abstract
The methanol extract of fresh leaves of Solanum melongena L. (Solanaceae) was evaluated for its capacity to alter the tone of isolated, pre-contracted guinea pig tracheal chains, as well as for its possible mechanism(s) of action. Using serial dilutions between 0.0025 and 2.5 mg/mL, the extract was found to cause a dose-dependent increase in the force of muscle contraction. The EC(50) value was 0.46 +/- 0.01 mg/mL. The concomitant use of acetylcholine 10(-5) M did not significantly affect the force of contraction induced by the extract. Histamine 10(-5) M added at about 40% to, and salbutamol 10(-6) M antagonized by about 30% its constrictive effect. Chlorpheniramine 10(-6) M, propanolol 10(-5) M, and nifedipine 10(-6) M did not significantly influence the extract-induced force of contraction, but atropine 3 x 10(-7) M reduced it by approximately 60%. These data suggest that the Solanum melongena extract exerted a bronchospasmogenic rather than a bronchospasmolytic effect, probably through muscarinic receptor stimulation.

Abstract
Phytochemical analysis of the leaves of Acnistus arborescens (Solanaceae) resulted in the isolation of two new epimeric withaphysalins (17S,20R,22R)-5beta,6beta: 18,20-diepoxy-4beta,18-dihydroxy-1-oxowitha-24-enolide (2, 18R and 18S), together with the known withaphysalin F (1, 18R and 18S). Their structures were established by spectroscopic methods, including 2D NMR data and comparison with literature data. Compounds 1 and 2 dis-played potent cytotoxic activities against several cancer cell lines with IC50 values in the range of 0.20 to 1.46 microg/mL for 1 and 0.89 to 8.08 microg/mL for 2. The strong cytotoxicity presented by 1 suggests that in this series of compounds, the 2,3-unsaturated ketone moiety is an important pharmacophoric unit. The cytotoxic activity seemed to be related to DNA synthesis inhibition, as revealed by the reduction of 5-bromo-2'-deoxyuridine incorporation after 24 hours of incubation on leukemic cells.

Abstract
Diverse self-incompatibility (SI) mechanisms permit flowering plants to inhibit fertilization by pollen that express specificities in common with the pistil. Characteristic of at least two model systems is greatly reduced recombination across large genomic tracts surrounding the S-locus, which regulates SI. In three angiosperm families, including the Solanaceae, the gene that controls the expression of gametophytic SI in the pistil encodes a ribonuclease (S-RNase). The gene that controls pollen SI expression is currently unknown, although several candidates have recently been proposed. Although each candidate shows a high level of polymorphism and complete allelic disequilibrium with the S-RNase gene, such properties may merely reflect tight linkage to the S-locus, irrespective of any functional role in SI. We analyzed the magnitude and nature of nucleotide variation, with the objective of distinguishing likely candidates for regulators of SI from other genes embedded in the S-locus region. We studied the S-RNase gene of the Solanaceae and 48A, a candidate for the pollen gene in this system, and we also conducted a parallel analysis of the regulators of sporophytic SI in Brassica, a system in which both the pistil and pollen genes are known. Although the pattern of variation shown by the pollen gene of the Brassica system is consistent with its role as a determinant of pollen specificity, that of 48A departs from expectation. Our analysis further suggests that recombination between 48A and S-RNase may have occurred during the interval spanned by the gene genealogy, another indication that 48A may not regulate SI expression in pollen.

Abstract
PURPOSE Previous work demonstrates that oleanolic acid (OA), a triterpene widely distributed in plants, shows gastroprotective effect in the ethanol, aspirin and pilorous ligature-induced gastric ulcer in rats as well as in the ethanol/hydrochloric acid-induced ulcer in mice. The aim of this work was to assess the healing effect of OA in the acetic acid-induced chronic gastric ulcer model in rats. METHODS Chronic gastric lesions were induced in male Sprague-Dawley rats with acetic acid. OA was administered orally during 14 days at 25, 50 and 100 mg/kg per day. Ranitidine (50 mg/kg) and the vehicle were used as controls. The ulcer area (mm2) and the curative ratio (%) were determined. Histological preparations were carried out for comparative purposes. RESULTS The effect of OA was significantly different as compared to the control reducing the lesion area (in mm2) from 39+/-7 in controls to 17.8+/-1.9 and 9.4+/-1.1 at the doses of 50 and 100 mg/kg, respectively. The curative ratio was 54.5 and 76% for the compound at 50 and 100 mg/kg, while ranitidine at 50 mg/kg reduced the lesion area to 6.9+/-0.8 with a curative ratio of 84%. Mucosal thickness increased from 342 microm in controls to 540 microm in oleanolic acid- (100 mg/kg) and 945 microm in ranitidine-treated animals. Histological examination of the stomach showed regeneration of the lesions. CONCLUSIONS OA improves healing of chronic gastric lesions in rats. The low toxicity and widespread occurrence of OA in plants suggest a potential for the development of the triterpene or their derivatives as a new antiulcer drug.

Abstract
Secondary metabolites, at least the major ones present in a plant, apparently function as defence (against herbivores, microbes, viruses or competing plants) and signal compounds (to attract pollinating or seed dispersing animals). They are thus important for the plant's survival and reproductive fitness. Secondary metabolites therefore represent adaptive characters that have been subjected to natural selection during evolution. Molecular phylogenies of the Fabaceae, Solanaceae and Lamiaceae were reconstructed and employed as a framework to map and to interpret the distribution of some major defence compounds that are typical for the respective plant families; quinolizidine alkaloids and non-protein amino acids for legumes; tropane and steroidal alkaloids for Solanaceae, and iridoids and essential oils for labiates. The distribution of the respective compounds appears to be almost mutually exclusive in the families studied, implying a strong phylogenetic and ecological component. However, on a closer look, remarkable exceptions can be observed, in that certain metabolites are absent (or present) in a given taxon, although all the neighbouring and ancestral taxa express (or do not express, respectively) the particular trait. It is argued that these patterns might reflect differential expression of the corresponding genes that have evolved earlier in plant evolution. The inconsistent secondary metabolite profiles mean that the systematic value of chemical characters becomes a matter of interpretation in the same way as traditional morphological markers. Thus, the distribution of secondary metabolites has some value for taxonomy but their occurrence apparently reflects adaptations and particular life strategies embedded in a given phylogenetic framework.

Abstract
Traditional medicine is a primary source for the study of medicinal plants. In some countries, knowledge about the therapeutic use of medicinal plants is very deep and very often 'magical' plants also are used to diagnose and treat illnesses. The study of these plants can help in the research of metabolites active on the central and peripheral nervous system. Brugmansia arborea (L.) Lagerheim (Solanaceae) is used in the northern Peruvian Andes for magic-therapeutic purposes and the present study examined the effect of three pure tropane alkaloids from Brugmansia arborea (L.) Lagerhein (Solanaceae) on morphine withdrawal in vitro. All the tropane alkaloids isolated from Brugmansia arborea (L.) (10(-7), 5 x 10(-7), 10(-6) m) significantly and in a concentration dependent manner reduced morphine withdrawal. The results of the present study suggest that these alkaloids may be a potential anti-additive agent.
