Abstract
BACKGROUND Plants in cliff habitats may evolve specific reproductive strategies to cope with harsh environments, and unraveling these reproductive characteristics can improve our understanding of survival strategies and lithophyte evolution. This understanding is especially important for efforts to protect rare and endemic plants. Here, we investigated the reproductive biology of Lonicera oblata, an endangered lithophytic shrub that is scattered in highly fragmented and isolated cliff habitats of the Taihang and Yan mountains in North China. RESULTS Flowers of L. oblata are herkogamous and protandrous, characteristics that can prevent autogamy at the single-flower level, and insects are necessary for pollination. The outcrossing index, pollen/ovule ratio, and the results of hand pollination were measured and all revealed a mixed mating system for L. oblata, that combines cross-fertilization and partial self-fertilization. The floral traits of L. oblata of zygomorphic and brightly yellowish corolla, heavy fragrance, and rich nectar, suggest an entomophilous pollination system. Sweat bees were observed as the most effective pollinators but their visiting frequencies were not high. Pollen limitation may limit the reproductive success of L. oblata. CONCLUSIONS We determined the reproductive characteristics of L. oblata, a critically endangered species endemic to cliffs in North China, providing insight into its endangerment and suggesting conservation strategies. L. oblata has highly pollinator-dependent self-fertilization as part of a mixed mating system. Floral features such as low-flowering synchrony, asynchronous anthers dehiscence, and high duration of stigma receptivity, improve pollination efficiency in the case of low pollinator service. Our work provides reference information to understand the survival strategies and conservation of L. oblata and other lithophytes.

Abstract
BACKGROUND Plants have remarkable diversity in petal colour through the biosynthesis and accumulation of various pigments. To better understand the mechanisms regulating petal pigmentation in Lonicera japonica, we used multiple approaches to investigate the changes in carotenoids, anthocyanins, endogenous hormones and gene expression dynamics during petal colour transitions, i.e., green bud petals (GB_Pe), white flower petals (WF_Pe) and yellow flower petals (YF_Pe). RESULTS Metabolome analysis showed that YF_Pe contained a much higher content of carotenoids than GB_Pe and WF_Pe, with α-carotene, zeaxanthin, violaxanthin and γ-carotene identified as the major carotenoid compounds in YF_Pe. Comparative transcriptome analysis revealed that the key differentially expressed genes (DEGs) involved in carotenoid biosynthesis, such as phytoene synthase, phytoene desaturase and ζ-carotene desaturase, were significantly upregulated in YF_Pe. The results indicated that upregulated carotenoid concentrations and carotenoid biosynthesis-related genes predominantly promote colour transition. Meanwhile, two anthocyanins (pelargonidin and cyanidin) were significantly increased in YF_Pe, and the expression level of an anthocyanidin synthase gene was significantly upregulated, suggesting that anthocyanins may contribute to vivid yellow colour in YF_Pe. Furthermore, analyses of changes in indoleacetic acid, zeatin riboside, gibberellic acid, brassinosteroid (BR), methyl jasmonate and abscisic acid (ABA) levels indicated that colour transitions are regulated by endogenous hormones. The DEGs involved in the auxin, cytokinin, gibberellin, BR, jasmonic acid and ABA signalling pathways were enriched and associated with petal colour transitions. CONCLUSION Our results provide global insight into the pigment accumulation and the regulatory mechanisms underlying petal colour transitions during the flower development process in L. japonica.

Abstract
AGLl9 is an important regulator for flowering in plants and critical in controlling the morphogenesis of flower organs. The fulllength cDNAs of AGL19in conventional Lonicera macranthoides (Lm-AGL19) and the mutant 'Xianglei' cultivar (Lm-XL-AGL19) were obtained using rapid amplification of cDNA ends and the expression vectors for Lm-XL-AGL19were constructed to investigate the roles of AGL19 in the 'Xianglei' cultivar. Lm-AGL19 (GenBank: MK419948) and Lm-XL-AGL19 (GenBank: MK419948) were isolated from the conventional variety and 'Xianglei' cultivar of L. macranthoides, respectively. Lm-AGL19 is 1274 bp in length, whereas Lm-XL-AGL19 is 1264-bp long, and both include a 654 bp open reading frame, encoding 217 amino acids, which has a highly conserved MADS_MEF2_like domain and a moderately conserved K-box domain, belonging to the type II MADS-box family of genes. Quantitative real-time polymerase chain reaction indicated that the expression levels of these genes at different flowering stages were significantly different, and that the genes were also expressed in stems and leaves. Lm-XL-AGL19 is underexpressed at flowering period 5 that the key time node for corolla expansion and nonexpansion, while LM-AGL19 is overexpressed during this flowering period. AGL19 was speculated to be a functional gene causing different phenotypes in the two L. macranthoides varieties. The successfully constructed plant expression vector provides an experimental reference for further research on the function of this gene and the basis for the excellent phenotype of L. macranthoides 'Xianglei'.

Abstract
Winter underpins key ecological processes, such as dormancy loss and seedling emergence. Enhanced warm spells, together with warming are occurring and will continue in the future. The consequences of these climate phenomena on germination were investigated among co-occurring woody plants, whose seeds are bird-dispersed in autumn and require cold stratification for spring emergence. Seeds from nine common southeastern USA plants were collected in autumn. We verified that seeds of the study species required cold stratification for dormancy loss. We then examined the following aspects in the laboratory or field: effect of warm spells during cold stratification on germination, effect of a warm spell during winter on seed survival and germination phenology, and effect of warming from autumn dispersal through winter dormancy loss on timing of germination. While no consistent effects of warm spells were found in the laboratory on quantity of germination, warm spells advanced spring field germination for several species. Some species germinated during cold stratification and during warm spells, especially extreme spells, in the laboratory. In the field, about half of Lonicera maackii seedlings that emerged with a warm spell died by late winter. With warming from autumn through spring, laboratory germination shifted from spring to predominately autumn for some species. With precocious germination during warm spells or germination phenology shifts, two scenarios are possible. Seedlings may die during winter, reducing the size of the soil seed bank and number of emergents, or they would survive in warmer winters, which would give them a competitive advantage over spring-emerging seedlings.

Abstract
BACKGROUND Lonicera japonica Thunb. (L. japonica) has the functions of clearing away heat and detoxifying, broad-spectrum antibacterial and anti-virus, etc. More than 70% of anti-inflammatory and cold Chinese patent medicines contain L. japonica. Trichomes comprise specialized multicellular structures that have the capacity to synthesize and secrete secondary metabolites and protect plants from biotic and abiotic stresses. The extraction of trichome secretions has great commercial value. However, little is known about the trichome formation mechanism in L. japonica. Therefore, the study of trichome development between different varieties provides a basis for selecting suitable planting resources. RESULTS Here, we present a genome-wide comparative transcriptome analysis between two L. japonica cultivars, toward the identification of biological processes and functional gene activities that occur during flowering stage trichome development. In this study, the density and average lengths of flower trichomes were at their highest during three-green periods (S2). Using the Illumina RNA-Seq method, we obtained 134,304 unigenes, 33,733 of which were differentially expressed. In an analysis of 40 differentially expressed unigenes (DEGs) involved in trichome development, 29 of these were transcription factors. The DEGs analysis of plant hormone signal transduction indicated that plant growth and development may be independent of gibberellin (GA) and cytokinine (CTK) signaling pathways, and plant stress may be independent of jasmonic acid (JA) and ethylene (ET) signaling pathways. We screened several genes involved in the floral biosynthesis of odors, tastes, colors, and plant hormones, and proposed biosynthetic pathways for sesquiterpenoid, triterpenoid, monoterpenoid, flavonoid, and plant hormones. Furthermore, 82 DEGs were assigned to cell cycles and 2616 were predicted as plant resistance genes (PRGs). CONCLUSIONS This study provides a comprehensive characterization of the expression profiles of flower development during the seven developmental stages of L. japonica, thereby offering valuable insights into the molecular networks that underly flower development in L. japonica.

Abstract
BACKGROUND Lonicera japonica Thunb. flower has been used for the treatment of various diseases for a long time and attracted many studies on its potential effects. Transcription factors (TFs) regulate extensive biological processes during plant development. As the restricted reports of L. japonica on TFs, our work was carried out to better understand the TFs' regulatory roles under different developmental stages in L. japonica. RESULTS In this study, 1316 TFs belonging to 52 families were identified from the transcriptomic data, and corresponding expression profiles during the L. japonica flower development were comprehensively analyzed. 917 (69.68%) TFs were differentially expressed. TFs in bHLH, ERF, MYB, bZIP, and NAC families exhibited obviously altered expression during flower growth. Based on the analysis of differentially expressed TFs (DETFs), TFs in MYB, WRKY, NAC and LSD families that involved in phenylpropanoids biosynthesis, senescence processes and antioxidant activity were detected. The expression of MYB114 exhibited a positive correlation with the contents of luteoloside; Positive correlation was observed among the expression of MYC12, chalcone synthase (CHS) and flavonol synthase (FLS), while negative correlation was observed between the expression of MYB44 and the synthases; The expression of LSD1 was highly correlated with the expression of SOD and the total antioxidant capacity, while the expression of LOL1 and LOL2 exhibited a negative correlation with them; Many TFs in NAC and WRKY families may be potentially involved in the senescence process regulated by hormones and reactive oxygen species (ROS). The expression of NAC19, NAC29, and NAC53 exhibited a positive correlation with the contents of ABA and H2O2, while the expression of WRKY53, WRKY54, and WRKY70 exhibited a negative correlation with the contents of JA, SA and ABA. CONCLUSIONS Our study provided a comprehensive characterization of the expression profiles of TFs during the developmental stages of L. japonica. In addition, we detected the key TFs that may play significant roles in controlling active components biosynthesis, antioxidant activity and flower senescence in L. japonica, thereby providing valuable insights into the molecular networks underlying L. japonica flower development.

Abstract
Finding chromium-accumulating plants is of great interest for phytoremediation of soil contaminated by chromium (Cr). Inspired by Traditional Chinese Medicine, we examined the Cr-resistance and Cr-accumulation of Lonicera japonica Thunb. After a two-phase study using both soil and water culture, we found that L. japonica could be a novel Cr-accumulating plant, which contains an average Cr(III) content of 1297.14 mg.kg-1 in its leaves. The Cr enrichment factor and the Cr transport coefficient of Lonicera japonica was 5.19 and 1.79, respectively. Lonicera japonica is the fifth Cr-accumulating plant discovered worldwide, and the first Cr-accumulating woody plant ever discovered. The results support the conclusions drawn from studies of Cr-accumulating Leersia hexandra that oxalic acid production can increase Cr tolerance whereas citric acid or malic acid has no effect, suggesting that oxalic acid might be a common reason for Cr tolerance in all Cr-accumulating plants. Moreover, this study revealed that the production of anthocyanin and carotene can also increase Cr(III) tolerance, suggesting that anthocyanin and carotene might also account for Cr tolerance in Cr-accumulating plants. We believe that the discovery of Lonicera japonica as a Cr-accumulating plant will offer great opportunities in phytoremediation, and the success should be a strong sign that Traditional Chinese Medicine harbors more secrets to be uncovered with modern science.

Abstract
APETALA1 (AP1), a floral meristem identity gene controls the flowering time and floral transition, and plays an important role in inflorescence and floral organ development. The full-length cDNA for AP1 was obtained by rapid amplification ofthe cDNA ends (RACE) so that the roles of AP1 in Lonicera macranthoides (Lm-AP1) could be better understood. AP1 (accession number in GenBank: MF418642) consisted of a 729-bp open reading frame encoding a protein that contained 242 amino acids, had a deduced molecular mass of 27.9919 kDa and a theoretical isoelectric point of 8.75. No signal peptide or transmembranedomains were detected in the sequences located in the nucleus, but it contained conserved sequences for MADS and the K-box. In the secondary structure, the alpha helix accounts for 60.74%, the beta turn 3.72%. The real-time polymerase chain reaction revealed that AP1 was more highly expressed in flowers, especially at the fourth flowering stage, which implied that it may play a role in flower development. Other L. macranthoides organs, such as stems and leaves, also expressed AP1. This research provided the basis for further analysis of the AP1 functional mechanism during L. macranthoides development.

Abstract
BACKGROUND Interest in organic blue honeysuckle berries has increased in recent years. They are rich in various health-promoting compounds which are sensitive to different environmental factors and are modified during the growing season. RESULTS Honeysuckle berries from different locations differed significantly in their contents of primary and secondary metabolites. The location Ogulin, with the highest altitude and consequently high UV radiation, had the highest phenolic content (259.85 mg per 100 g). Additionally, Vukovski Vrh, with the lowest temperature, had the highest ascorbic acid content (36.83 mg per 100 g), while Šmartno pri Litiji and Višnja Gora, with the highest precipitation, had the highest organic acid contents (885.85 and 850.01 mg per 100 g respectively). A combination of stressful environmental conditions of temperature, water source and light intensity led to the highest saponin content in Višnja Gora (695 mg per 100 g), the highest tannin content in Dolnje Impolje (134 mg per 100 g) and the highest sugar content (2585.45 mg per 100 g) in Vučetinac. CONCLUSION The contents of bioactive substances were influenced by various environmental factors such as temperature, UV radiation, altitude, light intensity and fruit ripening stage. Different compounds respond distinctly to different environmental factors. © 2017 Society of Chemical Industry.

One consequence of biological invasions is altered risk of exposure to infectious diseases in human and animal populations. The distribution and prevalence of mosquito-borne diseases depend on the complex interactions between the vector, the pathogen, and the human or wildlife reservoir host. These interactions are highly susceptible to disturbance by invasive species, including terrestrial plants. We conducted a 2-year field experiment using a Before-After/Control-Impact design to examine how removal of invasive Amur honeysuckle (Lonicera maackii) in a forest fragment embedded within a residential neighborhood affects the abundance of mosquitoes, including two of the most important vectors of West Nile virus, Culex pipiens and Cx. restuans. We also assessed any potential changes in avian communities and local microclimate associated with Amur honeysuckle removal. We found that (1) removal of Amur honeysuckle reduces the abundance of both vector and non-vector mosquito species that commonly feed on human hosts, (2) the abundance and composition of avian hosts is altered by honeysuckle removal, and (3) areas invaded with honeysuckle support local microclimates that are favorable to mosquito survival. Collectively, our investigations demonstrate the role of a highly invasive understory shrub in determining the abundance and distribution of mosquitoes and suggest potential mechanisms underlying this pattern. Our results also give rise to additional questions regarding the general impact of invasive plants on vector-borne diseases and the spatial scale at which removal of invasive plants may be utilized to effect disease control.

Abstract
Although encroaching woody plants have reduced the global extent of grasslands, continuing increases in soil nitrogen availability could slow this trend by favoring resident herbaceous species. At the same time, projected increases in rainfall variability could promote woody encroachment by aligning spatiotemporal patterns of soil moisture availability with the needs of woody species. We evaluated the responses of two deciduous woody species to these simulated environmental changes by planting seedlings of Quercus palustris and Lonicera maackii into tallgrass prairie communities grown under a factorial combination of increased rainfall variability and nitrogen addition. Lonicera maackii growth was reduced 20% by nitrogen addition, and increased rainfall variability led to 33% larger seedlings, despite greater competition for light and soil resources. In contrast, Q. palustris growth showed little response to either treatment. Increased rainfall variability allowed both species to retain their leaves for an additional 6.5 d in autumn, potentially in response to wetter end-of-season shallow soils. Our findings suggest increases in rainfall variability will counteract the inhibitory effect of nitrogen deposition on growth of L. maackii, extend autumn phenology, and promote the encroachment of some woody species into grasslands.

Abstract
The degradation dynamics and dietary risk assessments of thiamethoxam and thiacloprid during Lonicera japonica planting, drying, and tea brewing processes were systematically investigated using high-performance liquid chromatography. The half-lives of thiamethoxam and thiacloprid were 1.0-4.1 d in the honeysuckle flowers and leaves, with degradation rate constants k ranging from -0.169 to -0.696. The safety interval time was 7 d. The sun- and oven-drying (70 °C) percent digestions were 59.4-81.0% for the residues, which were higher than the shade- and oven-drying percentages at lower temperatures (30, 40, 50, and 60 °C, which ranged from 37.7% to 57.0%). The percent transfers of thiamethoxam and thiacloprid were 0-48.4% and 0-25.2%, respectively, for the different tea brewing conditions. On the basis of the results of this study, abiding by the safety interval time is important, and using reasonable drying methods and tea brewing conditions can reduce the transfer of thiamethoxam and thiacloprid to humans.

Abstract
Polyploidization is an effective method to achieve a higher yield of secondary metabolism active ingredients in medicinal plants. Polyphenols are the main active substances that contribute to the antioxidant activity of Lonicera japonica. For studying on the effect of chromosome doubling and harvest time on the dynamic accumulation of the main active substances and antioxidant capabilities of L. japonica, the polyphenol composition contents (7 phenolic acids and 3 flavonoids) and the antioxidant capacity in buds and flowers of diploid and tetraploid L. japonica at six different growth stages were determined by HPLC-DAD and three common antioxidant assays (FRAP, OH RSC and DPPH ARP), and the correlation between the dynamic accumulation of the polyphenol components and antioxidant capacity was also analyzed in current research. The results indicated that the content of the most determined phenolic acids and flavonoids and the antioxidant capacity in most of the growth stages from tetraploid plants were significantly higher than those in the diploid plants. Furthermore, the changes in the antioxidant activity presented a significant positive correlation with the variations in the chlorogenic acid, rutin, hyperoside, luteoloside in the two ploidy levels of L. japonica plants. The higher yields of chlorogenic acid (158.97, 164.00, 199.85 mg), luteoloside (5.44, 4.03, 6.31 mg), hyperoside (1.15, 1.06, 1.30 mg) and total flavonoids (9.87, 8.67, 11.10 mg) from 100 buds or flowers in tetraploid plants occurred during the S3-S5 stages, and these stages also exhibited higher antioxidant activities. Therefore, the stages of S3-S5 are recommended as the best time for harvesting high-yield, high-quality tetraploid Flos Lonicerae Japonicae.

Abstract
A greenhouse pot experiment was conducted to study the impact of arbuscular mycorrhizal fungi--Glomus versiforme (Gv) and Rhizophagus intraradices (Ri) on the growth, Cd uptake, antioxidant indices [glutathione reductase (GR), ascorbate peroxidase (APX), superoxide dismutase (SOD), catalase (CAT), ascorbate (ASA), glutathione (GSH) and malonaldehyde (MDA)] and phytochelatins (PCs) production of Lonicera japonica in Cd-amended soils. Gv and Ri significantly increased P acquisition, biomass of shoots and roots at all Cd treatments. Gv significantly decreased Cd concentrations in shoots and roots, and Ri also obviously reduced Cd concentrations in shoots but increased Cd concentrations in roots. Meanwhile, activities of CAT, APX and GR, and contents of ASA and PCs were remarkably higher in Gv/Ri-inoculated plants than those of uninoculated plants, but lower MDA and GSH contents in Gv/Ri-inoculated plants were found. In conclusion, Gv and Ri symbiosis alleviated Cd toxicity of L. japonica through the decline of shoot Cd concentrations and the improvement of P nutrition, PCs content and activities of GR, CAT, APX in inoculated plants, and then improved plant growth. The decrease of shoot Cd concentrations in L. japonica inoculated with Gv/Ri would provide a clue for safe production of this plant from Cd-contaminated soils.

Abstract
Lonicera macranthoides Hand.-Mazz (L. macranthoides) is a medicinal herb that is widely distributed in southern China. The biosynthetic and metabolic pathways for a core secondary metabolite in L. macranthoides, chlorogenic acid (CGA), have been elucidated in many species. However, the mechanisms of CGA biosynthesis and the related gene regulatory network in L. macranthoides are still not well understood. In this study, CGA content was quantified by high performance liquid chromatography (HPLC), and CGA levels differed significantly among three tissues; specifically, the CGA content in young leaves (YL) was greater than that in young stems (YS), which was greater than that in mature flowers (MF). Transcriptome analysis of L. macranthoides yielded a total of 53,533,014 clean reads (average length 90 bp) and 76,453 unigenes (average length 703 bp). A total of 3,767 unigenes were involved in biosynthesis pathways of secondary metabolites. Of these unigenes, 80 were possibly related to CGA biosynthesis. Furthermore, differentially expressed genes (DEGs) were screened in different tissues including YL, MF and YS. In these tissues, 24 DEGs were found to be associated with CGA biosynthesis, including six phenylalanine ammonia lyase (PAL) genes, six 4-coumarate coenzyme A ligase (4CL) genes, four cinnamate 4-Hydroxylase (C4H) genes, seven hydroxycinnamoyl transferase/hydroxycinnamoyl-CoA quinate transferase HCT/HQT genes and one coumarate 3-hydroxylase (C3H) gene.These results further the understanding of CGA biosynthesis and the related regulatory network in L. macranthoides.

Abstract
The paper is aimed to establish a method of residue analysis for thiamethoxam and to study its degradation dynamic and final residue and its standard of safe application of thiamethoxam on Lonicera japonica. Samples extracted with methanol by ultrasonication were purified with dichloromethane by liquid-liquid extraction and SPE column and analysed by HPLC-UV. The results showed that average rate was 84.91%-94.44% and RSD 1.74%-4.96% with addition of thiamethoxam in respectively diverse concentration, which meets inspection requirement of pesticide residue. Two kinds of dosages of thiamethoxam were treated- varying from recommended dosage (90 g x hm(-2)) to high dosage (135 g x hm(-2)), Results of two years test showed that thiamethoxam was degraded more than 90% seven days after application and the half - life period of thiamethoxam was 1.54-1.66 d. The digestion rate of thiamethoxam was fast in the L. japonica. The recommended MRL of thiamethoxam in the L. japonica is 0.1 mg x kg(-1), the dosage of 25% thiamethoxam WDG from 90-135 g x hm(-2) is sprayed less than three times a year on L. japonica and 14 days is proposed for the safety interval of the last pesticide application's and harvest's date.

Abstract
OBJECTIVE To explore the germination conditions of Lonicera hypoglauca sand culture seeds and the effects of sand culture seedlings sterilization. METHODS 0.1% HgCl2 with different sterilization time, different illumination time and temperature culture condition were adopted to study the germination conditions of sand culture seeds. Different sterilization treatments and different hardening-seedling days were used to test the sterilization effect of sand culture seedlings. RESULTS The sterilization effect of the combination of 75% ethanol 30 s + 0.1% HgCl2 5 min on Lonicera hypoglauca seeds was the optimum,with the average pollution rate of 15.56%, and the average germination rate reached 51.11%. The combination of varied temperature-room temperature under light for 12 h/d was the best, with the average germination rate peaked at 75.49%, and the average germination potential reached 68.36%. The treatment of detergent liquor scrub-tap water wash on the part above the hypocotyl, which was sand cultured under the opening condition and had no root, showed the best sterilization effect, with the average pollution rate was zero, and the average survival rate peaked at 100.00%. The sterilization effect of sand culture seedlings, which was disinfected after cleaning by detergent liquor scrub-tap water wash after hardening-seeding for 30 days, was the best, with the average pollution rate of 50.00%, and the average survival rate of 100.00%. CONCLUSION The best sterilization effect is the combination of 75% ethanol 30 s + 0.1% HgCl2 5 min; Lighting for 12 h/d of varied temperature-room temperature is regarded as the optimum culture condition. The treatment of detergent liquor scrub-tap water wash treatment on the part above the hypocotyl,which is sand cultured under the opening condition and had no root, shows the best sterilization effect. For the sand culture seedlings, before inoculated in subculture medium, should be hardening-seedling for some days and sterilized after detergent liquor scrub-tap water wash.

Abstract
We collected 22 cultivated population of Lonicera japonica from 17 areas. The characteristics of non-glandular hairs were observed and measured by the scanning electron microscopy. The principal components analysis and correlation analysis were conduct based on length and density of L. japonica. The results showed a significant negative correlation between length and density of non-glandular hairs, and the characteristics of non-glandular was not corrrelated significantly with latitude. The correlation results indicated that the density was a key to separate "Damaohua" and "Jizhuahua". The contribution of climate and soil was important to the cultivated population. This reminded that the characteristics of non-glandular hairs were affected by environmental and genetic interaction.

Abstract
Sixty-three morphological traits from 743 specimens of the 41 taxa within the cultivated Lonicera japonica were observed and measured, such as the height of plants, the length of leaf, the width of leaf, the length of anther, the alabastrum's number of one branch, the color of alabastrum and so on. A numerical taxonomy is presented by using the cluster analysis, principal components analysis (PCA) and factor analysis. Sixteen of 63 characters were screened by means of PCA and used for cluster analysis of 41 taxa with the method of Ward linkage and average euclidean distance. The cluster analysis showed that the 41 taxa could be divided into 5 groups when the Euclidean distance coefficient was 11.84. The factor analysis indicated that the shape of leaf, color of alabastrum, the pilosity and color of twiggery were of significance for the cultivated L. japonica classification. The results of this study will be a base for the core collection and breeding of L. japonica.

Abstract
BACKGROUND AND AIMS Tolerance and defence against herbivory are among the many mechanisms attributed to the success of invasive plants in their novel ranges. Because tolerance and defence against herbivory differ with the ontogeny of a plant, the effects of herbivore damage on plant fitness vary with ontogenetic stage and are compounded throughout a plant's lifetime. Environmental stresses such as light and nutrient limitations can further influence the response of the plant. Much is known about the response of plants in the seedling and reproductive adult stages, but less attention has been given to the pre-reproductive juvenile stage. METHODS Juvenile plants of the North American invasive Lonicera maackii were exposed to simulated herbivory under high and low light and nitrogen availability and growth, allocation patterns and foliar defensive chemistry were measured. In a second experiment, complete nutrient availability and damage type (generalist caterpillar or simulated) were manipulated. KEY RESULTS Juvenile plants receiving 50 % defoliation had lower total biomass and a higher root^:^shoot ratio than controls for all treatment combinations except low nitrogen/low light. Low light and defoliation increased root^:^shoot ratio. Light, fertilization and defoliation had little impact on foliar defensive chemistry. In the second experiment, there was a reduction in total biomass when caterpillar damage was applied. The root^:^shoot ratio increased under low soil fertility and was not affected by defoliation. Stem-diameter growth rates and specific leaf area did not vary by damage type or fertilization. Foliar protein increased through time, and more strongly in defoliated plants than in controls, while peroxidase activity and total flavonoids decreased with time. Overall, resource limitations were more influential than damage in the growth of juvenile L. maackii plants. CONCLUSIONS The findings illustrate that even when resources are limited, the tolerance and defence against herbivory of a woody invasive plant in the juvenile stage may contribute to the establishment and persistence of some species in a variety of habitats.

Abstract
A hydroponic experiment was carried out to investigate possible hormetic response induced by cadmium (Cd) in a potential hyperaccumulator-Lonicera japonica Thunb. The results showed that Cd at low concentrations induced a significant increase in plant growth, leaf water content and content of photosynthetic pigments in L. japonica, but decreased them at high concentrations, displayed inverted U-shaped dose response curves, confirming a typical biphasic hormetic response. The U-shaped dose response curves were displayed in malondialdehyde (MDA) and electrolyte leakage in leaves at low doses of Cd, indicating reduce oxidative stress and toxic effect. The increase of superoxide dismutase (SOD) and catalase (CAT) activities was observed along with the increased Cd concentration, indicative of increase in anti-oxidative capacity that ensures redox homeostasis is maintained. After 28 days exposure to 10 mg L(-1) Cd, stem and leaf Cd concentrations reached 502.96 ± 28.90 and 103.22 ± 5.62 mg kg(-1) DW, respectively and the plant had high bioaccumulation coefficient (BC) and translocation factor (TF'). Moreover, the maximum TF value was found at 2.5 mg L(-1) Cd treatment, implying that low Cd treatment improved the ability to transfer Cd from medium via roots to aerial structures. Taking together, L. japonica could be considered as a new plant to investigate the underlying mechanisms of hormesis and Cd tolerance. Our results suggest that hormetic effects should be taken into consideration in phytoremediation of Cd-contaminated soil.

Abstract
A hydroponic experiment was conducted to study the growth characteristics of Lonicera japonica under the stress of different concentrations (0, 0.5, 2.5, 5, 10, and 25 mg L-1 ) cadmium (Cd), aimed to explore the hormesis effect of low concentrations Cd on L. japonica. At < or =5 mg L-1 of Cd, the maximum root length, plant dry biomass, and the contents of chlorophyll a, chlorophyll b, and carotenoid of L. japonica increased significantly, with the increment being 13. 6%, 11.7%, 14. 0% ,10. 8%, and 54. 5%, respectively, as compared with the control. <5 mg L-1 of Cd also had a definite positive effect on the leaf water content. At> or = 10 mg L-1 of Cd, the growth of L. japonica was inhibited significantly. When exposed to 25 mg L-1 of Cd, the shoot Cd concentration of L. japonica reached 622. 93 mg kg-1 , suggesting that L. japonica had a strong capacity of Cd-hyperaccumulation. The dose range of the hormesis effect of Cd on L. japonica was 0.5-5 mg L-1 of Cd.

Abstract
Hyperaccumulators are important in the phytoremediation of cadmium (Cd)-contaminated soil. In this study, Cd accumulation and the interactions between Cd and four other trace elements (Fe, Mn, Cu, and Zn) in Lonicera japonica Thunb. were investigated. As a result of exposure to soil containing 50 mg kg(-1) Cd, stem and shoot Cd concentrations reached 344.49 ± 0.71 and 286.12 ± 9.38 μg g(-1) DW respectively, without showing symptoms of visible damage to the plants. This suggests that L. japonica has a strong tolerance to Cd. It is proposed that trace metal elements are involved in the Cd-detoxification mechanisms shown by hyperaccumulators. There is a synergistic interaction in accumulation and translocation between Cd and Fe and a significantly negative correlation between Cd and Cu or Zn concentrations in L. japonica plant tissues. The imbalanced trace element concentrations influences detoxification processes to Cd, therefore, L. japonica could be considered as a new Cd-hyperaccumulator model to investigate the metal tolerance strategies of plants.

Abstract
Phytoremediation using hyperaccumulators is a promising technique of removing soil pollutants. In the study, growth responses, cadmium (Cd) accumulation capability and physiological mechanisms of Lonicera japonica Thunb. under Cd stress were investigated. Exposed to 5 and 10 mg L(-1) Cd, the plants did not show any visual symptoms, furthermore, the height, dry biomass of leaves, roots and total and the chlorophyll (CHL) content were obtained different grade increase. When the concentration of Cd was up to 50 mg L(-1), the height, dry biomass of leaves and roots had not significant differences compared with the control. The indexes of tolerance (IT) were all above 0.8. The maintenance of high superoxide dismutase (SOD) and catalase (CAT) activities was observed along with the increased Cd concentration, suggesting strong internal detoxification mechanisms inside plant cells. After 21 days exposure to 25 mg L(-1) Cd, stem and shoot Cd concentrations reached 344.49+/-0.71 and 286.12+/-9.38 microg g(-1) DW, respectively and the plant had higher bioaccumulation coefficient (BC) and translocation factor (TF). According to these results, it was shown L. japonica had strong tolerance and accumulation capability to Cd, therefore it is a potential Cd-hyperaccumulator.

Abstract
OBJECTIVE To investigate the quality and quantity changes of Flos Lonicerace during flowering stages in Hanzhong GAP base in order for properly harvesting and quality control. METHOD The yield index of Flos lonicerace in four flowering stages was determined, and the contents of chlorogenic acid and the total flavonoid in the samples were determined by HPLC and the colorimetry, respectively. The volatile oils were extracted by the SFE-CO2 and the constituents were analyzed by GC-MS. RESULT The yield in the first two flowering times was attributed to about more than 80% of total yield, and the number of flower buds for each plant in the first time was almost the same as the sum of the other three times. The drying rate of the three-site green flowers kept the highest during the first flowering time, and the drying rate of the two-site white flowers kept the highest during the second flowering time. The contents of chlorogenic acid and the total flavonoid in the first flowering time were higher than those in the second, and among them, the two-site white flowers kept the highest, about 3.5% and 13.2%, respectively. For the sample flowers in in the second flowering time, the three-site green flowers kept the highest level of chlorogenic acid and the total flavonoid, about 2.7% and 11.6%, respectively. From the volatile oil samples in the five periods of Flos lonicerace in the first flowering time, 19 components were identified by GC-MS. They were composed by three types of compounds, n-diolefines, fatty acids and steroids. Nonacosane and hentriacontane had the relatively higher amount with more than 40% and 20%, respectively. The relative contents of vitamine E were higher too, about 8.15% - 10.43%. And, gamma-5-sitostene-3-ol, stigmasta-5,2-diene-3-ol and campesterol were also detected. Among these steroids, the relative contents of the first two were 4.90% - 6.9%, 1.06%- 4.10%, respectively. CONCLUSION The flowering samples in the first two times were attributed to the most to the total yield. The samples of the two-site white flower and the whole-white flower had the higher comprehensive quality. The components of vitamine E and the steroids in the volatile oil need to be paid more attention.

Abstract
OBJECTIVE To analyze the genetic diversity and differentiation degree of five Lonicera confusa populations. METHODS Random Amplified Polymorphic DNA (RAPD) markers were perfomed to amplify the discernible loci. RESULTS A total of 100 loci were obtained for all populations using ten primers, 87.00% of which were polymorphic (PPL = 87.00%). Analyzed by POPGENE, the average percentage of polymorphic loci was 58.86%. Nei's genetic diversity (H = 0.2647) and Shannon's information index (I = 0.4022) indicated that Lonicera confusa had a higher level of genetic diversity. The high value of differentiation( G(st) = 0.3839) showed that geographic isolation strongly influenced genetic differentiation among populations and there was a significant correlation between genetic distance and geographic distance (r = 0.8504, P = 96.80%). The clustering analysis was performed using softwares POPGENE and NTSYS-pc. Five populations were divided into 2 clusters, named cluster 1 (LFS, XX and NN) and cluster 2 (XW and HK). CONCLUSION Management strategies were proposed for species conservation and resource utilization of Lonicera confusa, including the protection from human disturbance to facilitate natural regeneration, construction of germplasm resources and cultivation of plants collected from different populations, in order to select elite lines for good agricultural practice (GAP) of medicinal materials.

Abstract
By using hydroponics, the growth and physiological characteristics of Lonicera japonica at different concentrations (0, 5, 10, 25, and 50 mg x L(-1)) of cadmium (Cd) were studied. The results showed that compared with the control, Cd stress had lesser effects on the growth of L. japonica. Within the range of test Cd concentrations, L. japonica biomass had less difference (P > 0.05) with the control, and at low concentration of Cd (5 mg x L(-1)), the total biomass and the biomasses of leaf and root were increased by 1.25%, 2.88 and 2.33%, respectively, illustrating that L. japonica had stronger resistance against Cd. Under low concentration Cd stress, the water content and soluble protein content in plant organs had some decrease, while the malondialdehyde (MDA) content in root and leaf increased by 51.90% and 23.07%, respectively, leaf chlorophyll and carotenoid contents increased by 15.87% and 24.89%, respectively, and superoxide dismutase (SOD) activity increased significantly. With increasing Cd concentration, the chlorophyll and carotenoid contents and SOD activity decreased to some extent.

Abstract
OBJECTIVE Effects of water stress on the growth of Lonicera japonica and quality of honeysuckle were studied. METHODS Different extent water stress treatment imposed to potted plants before the first florescence of honeysuckle, and the growth and related physiological indexes of Lonicera japonica were determined. RESULTS Shoot grow slowly as well as the increases of specific weight of leaf and the decrease of the yield of honeysuckle under water stress. The contents of chlorophyl in the leaves treated water stress all increased, and the content of soluble suger had a rising stream. The content of soluble protein in leaves of plant imposed by minor stress treatment was obviously higher than that of CK and severe stress treatment. As the stress was hard, the content of proline in leaves increased significantly. With water stress severing, the content of chlorogenic acid in the flower bud decreased very significantly than CK. CONCLUSION Water condition was a important factor affected the growth and development of shoots, leaves and flower buds as well as the quality of honeysuckle. In the cultivation of Loniccra japonica, irrigation timing and certain irrigation condition was necessary.

Abstract
In a greenhouse pot experiment,a gradient of soil Cd concentration was established by adding 0,50,100 and 200 mg CdCl2 x kg(-1) air-dried soil, and the seedlings of one-year-old Rosa davurica, Philadelphus schrenkii, Acer mandshurica and Lonicera maackii were transplanted. The measurement of the seedlings' chlorophyll fluorescence parameters and biomass accumulation after 70 days of transplanting showed that with increasing soil Cd content, all the test tree species had a decrease of Fv/Fm, phi(PSII), qP and biomass, but an increase of qN. A. mandshurica had the greatest responses, followed by P. schrenkii and L. maackii, and R. davurica. The tolerance of these tree species to soil Cd contamination followed the order of R. davurica > P. schrenkii and L. maackii > A. mandshurica.

Abstract
OBJECTIVE To study the effects of irrigation volume on the growth and quality of Lonicera japonica. METHOD Different volume of irrigation water was applied to the potted L. japonica before the first florescence of honeysuckle in order to keep the relative moisture content of the soil as 100%, 80%, 50%, 30%, and observe the growth and development of shoot and leaves, yield and quality of honeysuckle. RESULT As the of irrigation volume was reduced, the internodal elongation of shoot and the increase of the knot were restrained, and the yield of honeysuckle dropped. But the content of chlorogen acid in the buds treated by 80% irrigation volume was not affected, while that of the other treatment all decreased. The moisture contents of the leaves treated by 30% irrigation volume was significantly lower than that of the CK, while the specific leaf weight (SLW) increased significantly comparing to the CK. The content of chlorophyl in the leaves of 50% and 30% increased, while the ratio of chlorophyl A and B fell significantly. The content of dissoluble suger in the leaves of 80% and 50% irrigation volume was much higher than that in the CK. The results also showed that, the content of dissoluble protein in the leaves of 30% irrigation volume increased comparing with that in 50%, and the content of proline in leaveas of 30% irrigation volume increased significantly. CONCLUSION Using less irrigation volume (keeping 80% of relative moisture content of the soil) does not affect the quality of honeysuckle, but decreased dry weight of honeysuckle. It is necessary to take irrigation management during cultivation of honeysuckle.

Abstract
The soil quality of karst rocky desertification region were taken as case studies with four different recover and restoration measures for 13 years long-term fixed site harnessing in Guizhou Province, and plant diversity and soil fertility over different measures were investigated. The results showed that the plant diversity was the lowest, soil feritilities and ecosystem environment were the poorest in the control land with no restoration measure. The plant diversity rised evidently and the soil quality restorated to some degree in the measure of changing into a Zanthorylum bungeamum woods (Measure A) and the measure of changing into multispecies woods (Measure B). The diversity of auxiliary community were resumed to the best degree and soil quality were resumed to the best degree in measure of closed forest (Measure C). The plant diversity was higher and soil quality was best in measure of secondary forest (Measure D). Therefore, the proper biological measures and the essential engineering measures are effective to recover the serious degradation ecosystem in Karst mountain of Guizhou Province.

Abstract
Effects of invasive plant species on native plant species are frequently assumed or inferred from comparisons, but rarely quantified experimentally. Such quantification is important to assessing risks and impacts of invasives. We quantified the effects of Lonicera maackii, an exotic shrub invasive in many eastern North American forests, on survival, growth, and reproduction of three perennial herbs: Allium burdickii, Thalictrum thalictroides , and Viola pubescens. We predicted that the spring ephemeral, A. burdickii , would be most impacted, due to early leaf expansion of L. maackii. Field experiments were carried out in two deciduous forest stands, one (Gregg's Woodlot, GW) disturbed and the other (Western Woods, WW) relatively undisturbed. In each stand, individual herbs were transplanted into a blocked design of 60 plots where L. maackii was present, absent, or removed, and monitored for 5 growing seasons. Lonicera maackii did not affect survival of transplants, but reduced growth and final size of individuals of all three species. For two of the species, A. burdickii and V. pubescens, L. maackii reduced the proportion of live plants flowering in both stands, and reduced the seed or fruit number per flowering individual in GW. For T. thalictroides the proportion flowering was not affected, but seed number per flowering plant was reduced by L. maackii in both stands. For all three species, cumulative seed production over the course of the study was reduced by L. maackii. Overall, effects on the spring ephemeral, A. burdickii, were similar to effects on the other herbs. Because mortality of these established individuals was not affected, short-term studies might conclude forest herbs are unaffected by invasive shrubs. However, the growth and reproduction impacts documented here suggest that populations are impacted in the long-term.

Abstract
OBJECTIVE To study the relationship between the Geo-authentic and Geologic Background System (GBS) and physicochemical properties of cultivated soil in the Flos Lonicerae. METHOD The analysis on the physicochemical properties of cultivated soil, the geologic background system in 5 producing areas of Flos Lonicerae was compared. RESULT The distribution of genuine Flos Lonicerae was restricted by GBS, which was mainly restricted in the temperate continental monsoon semi-arid climate zone between north latitude 34-36 degrees and east longitude 113-118 degrees. CONCLUSION The most suitable soil for the genuine Flos Lonicerae is the neutral or weak alkali sandy loamy soil with higher ion exchanging capacity, and the soils from those producing areas are determined by soil-forming parent materials.
