Abstract
The European Commission requested EFSA to conduct a pest categorisation of Spodoptera frugiperda (Lepidoptera: Noctuidae) a pest with hosts in 27 plant families. Favoured hosts include maize, rice and sorghum (Poaceae). Hosts also include crops within the Brassicaceae, Cucurbitaceae, Solanaceae, Rutaceae and other families. S. frugiperda is a taxonomic entity with reliable methods for identification. It is regulated in the EU as a harmful organism whose introduction into the EU is banned. It is native to tropical and subtropical regions of the Americas and migrates to temperate regions in North and South America during the summer. Establishment in temperate areas is prevented by its inability to overwinter. S. frugiperda has been intercepted on plant produce entering the EU. Phytosanitary measures are available to impede entry via traded commodities. In 2016, S. frugiperda was reported damaging maize in Africa. Subsequent reports indicate that it continues to spread severely damaging maize and other crops. If S. frugiperda spreads into north Africa, the likelihood of adults migrating into the temperate EU increases. Within the scope and level of analysis appropriate for pest categorisation, the EFSA Plant Health Panel concludes that S. frugiperda could establish in a small area of the southern EU from where it is likely to enter more northern regions forming transient summer populations, particularly in maize growing regions where impacts on yield could occur. However, uncertainties regarding establishment remain. Considering the criteria within the remit of EFSA to assess as regards status as a potential Union quarantine pest (QP) or as a potential regulated non‐quarantine pest (RNQP), S. frugiperda satisfies the criteria to be regarded a Union QP but does not meet the criteria of (i) occurring in the EU territory, and (ii) plants for planting being the principal means of spread, criteria required for RNQP status.

Abstract
The Panel on Plant Health performed a pest categorisation of the strawberry bud weevil, Anthonomus signatus Say, (Coleoptera: Curculionidae), for the EU. A. signatus is a well‐defined and distinguishable species, recognised as a pest of strawberry (Fragaria) fruit production in eastern North America where it is also a pest of Rubus. There are reports of A. signatus associated with non‐rosaceous plants such as Mentha, Nepeta, Rhododendron and Solidago although whether such plants are true hosts is uncertain. This pest categorisation focuses on Fragaria and Rubus as hosts. Anthonomus signatus is not known to occur in the EU. It is listed in Annex IIAI of Council Directive 2000/29/EC. The international trade in Fragaria and Rubus plants for planting provides a potential pathway to introduce A. signatus from North America. Considering climatic similarities between North America and the EU, the thermal biology of A. signatus and host distribution in the EU, A. signatus has the potential to establish within the EU. There would be one generation per year, as in North America. As a pest of field grown Fragaria and Rubus, A. signatus would not be expected to establish in EU glasshouses. In North America, adults clip developing buds, preventing fruit development and reducing yield. Losses are variable and depend on the cultivars attacked. Severe crop losses have been reported. However, some Fragaria cultivars can compensate the loss of buds, e.g. by increasing the weight of fruits developing on remaining buds. Phytosanitary measures are available to reduce the likelihood of introduction of A. signatus from North America. All criteria assessed by EFSA for consideration as a potential Union quarantine pest are met. As A. signatus is not known to occur in the EU, this criterion assessed by EFSA to consider it as a Union regulated non‐quarantine pest is not met.

Abstract
The Panel on Plant Health performed a pest categorisation of the great spruce bark beetle, Dendroctonus micans (Kugelann), (Coleoptera: Curculionidae, Scolytinae), for the EU. D. micans is a well‐defined and distinguishable species, recognised mainly as a pest of spruce (Picea spp.) and pine (Pinus spp.) in Eurasia. Attacks on other conifers (Abies spp., Larix decidua, Pseudotsuga menziesii) are also reported. Supposedly originating from north‐eastern Eurasia, D. micans has spread westward and is now distributed throughout the EU (22 Member States). It is a quarantine pest listed in Annex IIB of Council Directive 2000/29/EC for Greece, Ireland and the United Kingdom (Northern Ireland, Isle of Man and Jersey) as protected zones. Wood, wood products, bark and wood packaging material of the conifers genera listed as hosts are considered as the main pathways for the pest, which is also able to disperse several kilometres by flight. The sib‐mating habits of the species allow each single female to start a new colony on her own. The pest's wide current geographic range suggests that it is able to establish anywhere in the EU where its hosts are present. The beetles attack living trees and usually complete their life cycle without killing their host, except under epidemic conditions at the limits of their distribution range, where hundreds of thousands of trees can be killed. Sitka spruce (Picea sitchensis) is particularly susceptible. Biological control using the very specific predatory beetle, Rhizophagus grandis, is a widespread and efficient option that has been implemented in all areas suffering from outbreaks. It is complemented by sanitary thinning or clear‐felling. All criteria assessed by EFSA for consideration as potential protected zone quarantine pest were met. The criteria for considering D. micans as a potential regulated non‐quarantine pest are not met since plants for planting are not the main pathway.

Abstract
Zusammenfassung. Laien treffen heute im Internet auf eine besonders große Vielfalt an Wissenschaftsinformationen. Wer hiervon profitieren will, muss Informationen auswählen, Verknüpfungen zwischen verschiedenen, oftmals konfligierenden Aussagen herstellen und deren Gültigkeit kritisch überprüfen. Anhand der Ergebnisse aus zwei Projekten aus dem SPP 1409 ‚Wissenschaft und Öffentlichkeit‘ zeigen wir, wie Laien diese Anforderungen bewältigen und auf welche kognitiven und motivationalen Ressourcen sie dabei zurückgreifen können. Obwohl erwachsene Laien bereits über vielfältige Kompetenzen im Umgang mit Wissenschaftsinformationen verfügen, deuten unsere Befunde auch auf einen Bedarf an pädagogischen Interventionen hin, um diese weiter zu verfeinern.

Abstract
BACKGROUND Cassava brown streak disease is emerging as the most important viral disease of cassava in Africa, and is consequently a threat to food security. Two distinct species of the genus Ipomovirus (family Potyviridae) cause the disease: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV). To understand the evolutionary relationships among the viruses, 64 nucleotide sequences from the variable P1 gene from major cassava producing areas of east and central-southern Africa were determined. METHODS We sequenced an amplicon of the P1 region of 31 isolates from Malawi and Tanzania. In addition to these, 33 previously reported sequences of virus isolates from Uganda, Kenya, Tanzania, Malawi and Mozambique were added to the analysis. RESULTS Phylogenetic analyses revealed three major P1 clades of Cassava brown streak viruses (CBSVs): in addition to a clade of most CBSV and a clade containing all UCBSV, a novel, intermediate clade of CBSV isolates which has been tentatively called CBSV-Tanzania (CBSV-TZ). Virus isolates of the distinctive CBSV-TZ had nucleotide identities as low as 63.2 and 63.7% with other members of CBSV and UCBSV respectively. CONCLUSIONS Grouping of P1 gene sequences indicated for distinct sub-populations of CBSV, but not UCBSV. Representatives of all three clades were found in both Tanzania and Malawi.

Abstract
Following a request from the European Commission, the European Food Safety Authority (EFSA) Plant Health (PLH) Panel analysed a dossier submitted by the Japanese authorities in order to clarify the host status of Citrus junos with regard to Xanthomonas citri pv. citri and Xanthomonas citri pv. aurantifolii, causal agents of citrus bacterial canker, and to indicate whether C. junos fruit could represent a pathway for the introduction of citrus bacterial canker into the European Union. In a previous opinion in the year 2014, the EFSA PLH Panel concluded that commercial fresh citrus fruit is generally pathway and that no commercially important Citrus species or variety can be considered as immune to citrus bacterial canker. In the current assessment, the EFSA PLH Panel analysed the two scientific papers provided by the Japanese authorities, as well as 16 additional papers identified through a systematic literature review. The PLH Panel considered that the conclusions of its previous opinion remain valid and that convergent lines of evidence provide sufficient demonstration that C. junos is a host of X. citri pv. citri and X. citri pv. aurantifolii. Therefore, there is no reason to consider the C. junos fruit differently from other citrus species. Consequently, the assessment of the general citrus fruit pathway from the 2014 opinion still applies. Uncertainties on these conclusions are a result of the scarce scientific evidence published on this subject in addition to the methodological and reporting limitations of the published papers.

Abstract
Users of social networking sites such as Facebook frequently post self-portraits on their profiles. While research has begun to analyze the motivations for posting such pictures, less is known about how selfies are evaluated by recipients. Although producers of selfies typically aim to create a positive impression, selfies may also be regarded as narcissistic and therefore fail to achieve the intended goal. The aim of this study is to examine the potentially ambivalent reception of selfies compared to photos taken by others based on the Brunswik lens model Brunswik (1956). In a between-subjects online experiment (N = 297), Facebook profile mockups were shown which differed with regard to picture type (selfie vs. photo taken by others), gender of the profile owner (female vs. male), and number of individuals within a picture (single person vs. group). Results revealed that selfies were indeed evaluated more negatively than photos taken by others. Persons in selfies were rated as less trustworthy, less socially attractive, less open to new experiences, more narcissistic and more extroverted than the same persons in photos taken by others. In addition, gender differences were observed in the perception of pictures. Male profile owners were rated as more narcissistic and less trustworthy than female profile owners, but there was no significant interaction effect of type of picture and gender. Moreover, a mediation analysis of presumed motives for posting selfies revealed that negative evaluations of selfie posting individuals were mainly driven by the perceived motivation of impression management. Findings suggest that selfies are likely to be evaluated less positively than producers of selfies might suppose.

Abstract
Thiopurine-related hematotoxicity in pediatric acute lymphoblastic leukemia (ALL) and inflammatory bowel diseases has been linked to genetically defined variability in thiopurine S-methyltransferase (TPMT) activity. While gene testing of TPMT is being clinically implemented, it is unclear if additional genetic variation influences TPMT activity with consequences for thiopurine-related toxicity. To examine this possibility, we performed a genome-wide association study (GWAS) of red blood cell TPMT activity in 844 Estonian individuals and 245 pediatric ALL cases. Additionally, we correlated genome-wide genotypes to human hepatic TPMT activity in 123 samples. Only genetic variants mapping to chromosome 6, including the TPMT gene region, were significantly associated with TPMT activity (P < 5.0 × 10-8 ) in each of the three GWAS and a joint meta-analysis of 1,212 cases (top hit P = 1.2 × 10-72 ). This finding is consistent with TPMT genotype being the primary determinant of TPMT activity, reinforcing the rationale for genetic testing of TPMT alleles in routine clinical practice to individualize mercaptopurine dosage.

Abstract
OBJECTIVES To identify the most cost-effective treatment strategy in patients with early stage (T1 and T2) cancers of the laryngeal glottis. DESIGN A Markov decision model populated using data from updated systematic reviews and meta-analyses, with attributable costs from NHS sources. Data on local control and mortality were obtained from updates of existing systematic reviews conducted for the NICE guideline on cancer of the upper aerodigestive tract. Procedure costs were sourced from NHS reference costs 2013/14 by applying tariffs associated with the appropriate health resource group code SETTING: The UK National Health Service. POPULATION Patients with early stage (T1 and T2) cancers of the laryngeal glottis. INTERVENTIONS Transoral laser microsurgery (TLM) and radiation therapy (RT). MAIN OUTCOME MEASURES Total costs, incremental costs and quality adjusted life years (QALYs) over a 10-year time horizon. RESULTS Radiation therapy as the initial treatment strategy was found to be more expensive (£2654 versus £623) and less effective (QALY reduction of 0.141 and 0.04 in T1a and T1b-T2 laryngeal cancers, respectively) than TLM. The dominance of TLM for T1a cancers was unchanged in most scenarios modelled in sensitivity analysis. For T1b-T2 laryngeal cancers, the result changed in numerous scenarios. In probabilistic sensitivity analysis, TLM was found to have a 71% and 58% probability of being cost-effective in T1a and T1b-T2 laryngeal cancers, respectively. CONCLUSIONS Transoral laser microsurgery is a cost-effective strategy to adopt in the management of T1a laryngeal cancers. Uncertainty remains over the optimal strategy to adopt in T1b-T2 laryngeal cancers.

Abstract
Background and Purpose : The aim of this study was to evaluate the efficacy, safety, and tolerability of cerebrolysin in the early recovery phase after acute ischemic stroke. Methods. This prospective, randomized, double-blinded, placebo-controlled, multicenter, parallel-group study enrolled a total of 100 patients within 18 h after the onset of stroke. The patients were treated with Cerebrolysin (30 mL over seven days followed by 10 mL until day 30) or placebo once daily over a period of four weeks. Efficacy was primarily assessed by the NIH Stroke Scale at day 30, and additional parameters included the modified Rankin Scale, the Clinical Global Impression, the Patient Global Satisfaction (PGS) and the Mini Mental State Examination (MMSE). Nonparametric statistical procedures employing the Wilcoxon-Mann-Whitney test were used for data analysis. Safety and tolerability were assessed by adverse events, vital signs, and laboratory parameters. Results.The estimated effect size on the change from baseline in the NIH Stroke Scale on day 30 indicated a medium to large superiority of cerebrolysin compared to placebo (Mann-Whitney [MW] 0.66; 95% confidence interval [CI] 0.55-0.78, P=0.005). Similar effect sizes were reported for the modified Ranking Scale (MW 0.65; 95% CI 0.54-0.76; P=0.010) and the Clinical Global Impression (MW 0.70; 95% CI 0.55-0.85; P=0.006). Effect sizes in the MMSE and PGS did not reach statistical significance. No significant group differences were seen in any of the safety parameters. Conclusions. Cerebrolysin was effective, safe, and well tolerated in the early recovery phase after acute ischemic stroke and significantly improved neurological and global function outcomes compared to placebo.

Abstract
The use of optical technologies may be beneficial when measuring breathing biomechanics. The purpose of this study was twofold: i) to enhance the optoelectronic plethysmography (OEP) algorithm performance for the volume estimation by the use of a novel volume calibration procedure and ii) to compare the OEP volumes gained by a commercial optoelectronic system against actual respiratory volumes measured by a breath-by-breath gas analyzer (BbB). The OEP volume algorithm calibration was performed by the use of a novel volume calibration procedure based on both a calibrator device that delivered known volumes changes and one ad-hoc designed software for the static and dynamic calibration analysis. OEP algorithm threshold, accuracy, repeatability and the volume algorithm calibration were investigated. Tidal volume (VT) measurements performed simultaneously by the calibrated OEP algorithm and BbB analyzer were compared. VT measured simultaneously by OEP and BbB was collected during submaximal exercise tests in five trained healthy participants in two conditions (with hunched shoulders and in normal shoulder position). The two methods were compared by linear regression and Bland-Altman analysis in both positions. The average difference between methods and the discrepancy were calculated. The OEP-BbB correlation was high in both positions, R2=0.92 and R2=0.97 for hunch and normal one, respectively. Bland-Altman analysis demonstrated that OEP algorithm systematic difference was lower than 100mL. The limits of agreement assessed in both positions are comparable. The difference between measurements suggesting that OEP may be a useful tool to analyze chest wall volume changes and breathing mechanics during intense exercise.

Abstract
BACKGROUND Small RNAs (sRNAs) are endogenous sRNAs that play regulatory roles in plant growth, development, and biotic and abiotic stress responses. In plants, one subset of sRNAs, microRNAs (miRNAs) exhibit tissue-differential expression and regulate gene expression mainly through direct cleavage of mRNA or indirectly via production of secondary phased siRNAs (phasiRNAs) that silence cognate target transcripts in trans. RESULTS Here, we have identified cassava (Manihot esculenta Crantz) miRNAs using high resolution sequencing of sRNA libraries from leaf, stem, callus, male and female flower tissues. To analyze the data, we built a cassava genome database and, via sequence analysis and secondary structure prediction, 38 miRNAs not previously reported in cassava were identified. These new cassava miRNAs included two miRNAs not previously been reported in any plant species. The miRNAs exhibited tissue-differential accumulation as confirmed by quantitative RT-PCR and Northern blot analysis, largely reflecting levels observed in sequencing data. Some of the miRNAs identified were predicted to trigger production of secondary phased siRNAs (phasiRNAs) from 80 PHAS loci. CONCLUSIONS Cassava is a woody perennial shrub, grown principally for its starch-rich storage roots, which are rich in calories. In this study, new miRNAs were identified and their expression was validated using qRT-PCR of RNA from five different tissues. The data obtained expand the list of annotated miRNAs and provide additional new resources for cassava improvement research.

Abstract
Geminiviruses multiply primarily in the plant phloem, but never in meristems. Their Rep protein can activate DNA synthesis in differentiated cells. However, when their single-stranded DNA is injected into the phloem by insects, no Rep is present for inducing initial complementary strand replication. Considering a contribution of translesion synthesis (TLS) polymerases in plants, four of them (Polη, Polζ, Polκ, Rev1) are highly and constitutively expressed in differentiated tissues like the phloem. Two geminiviruses (Euphorbia yellow mosaic virus, Cleome leaf crumple virus), inoculated either biolistically or by whiteflies, replicated in Arabidopsis thaliana mutant lines of these genes to the same extent as in wild type plants. Comparative deep sequencing of geminiviral DNAs, however, showed a high exchange rate (10(-4)-10(-3)) similar to the phylogenetic variation described before and a significant difference in nucleotide substation rates if Polη and Polζ were absent, with a differential response to the viral DNA components.

Abstract
The quantity of genomic DNA-A and DNA-B of African cassava mosaic virus (ACMV) and East African cassava mosaic virus Uganda (Uganda variant, EACMV-UG) was analysed using quantitative PCR to assess virus concentrations in plants from susceptible and tolerant cultivars. The concentrations of genome components in absolute and relative quantification experiments in single and mixed viral infections were determined. Virus concentration was much higher in symptomatic leaf tissues compared to non-symptomatic leaves and corresponded with the severity of disease symptoms. In general, higher titres were recorded for EACMV-UG Ca055 compared to ACMV DRC6. The quantitative assessment also showed that the distribution of both viruses in the moderately resistant cassava cv. TMS 30572 was not different from the highly susceptible cv. TME 117. Natural mixed infections with both viruses gave severe disease symptoms. Relative quantification of virus genomes in mixed infections showed higher concentrations of EACMV-UG DNA-A compared to ACMV DNA-A, but a marked reduction of EACMV-UG DNA-B. The higher concentrations of EACMV-UG DNA-B compared to EACMV DNA-A accumulation in single infections were consistent. Since DNA-B is implicated in virus cell-to-cell spread and systemic movement, the abundance of the EACMV-UG DNA-B may be an important factor driving cassava mosaic disease epidemic.

Abstract
The introduction of invasive species causes damages from the economic and ecological point of view. Interception of plant pests and eradication of the established populations are two management options to prevent or limit the risk posed by an invasive species. Management options generate costs related to the interception at the point of entry, and the detection and eradication of established field populations. Risk managers have to decide how to allocate resources between interception, field detection, containment, and eradication minimizing the expected total costs. In this work is considered an optimization problem aiming at determining the optimal allocation of resources to minimize the expected total costs of the introduction of Bemisia tabaci-transmitted viruses in Europe. The optimization problem takes into account a probabilistic model for the estimation of the percentage of viruliferous insect populations arriving through the trade of commodities, and a population dynamics model describing the process of the vector populations' establishment and spread. The time of field detection of viruliferous insect populations is considered as a random variable. The solution of the optimization problem allows to determine the optimal allocation of the search effort between interception and detection/eradication. The behavior of the search effort as a function of efficacy or search in interception and in detection is then analyzed. The importance of the vector population growth rate and the probability of virus establishment are also considered in the analysis of the optimization problem.

Abstract
Endogenous viral sequences are essentially 'fossil records' that can sometimes reveal the genomic features of long extinct virus species. Although numerous known instances exist of single-stranded DNA (ssDNA) genomes becoming stably integrated within the genomes of bacteria and animals, there remain very few examples of such integration events in plants. The best studied of these events are those which yielded the geminivirus-related DNA elements found within the nuclear genomes of various Nicotiana species. Although other ssDNA virus-like sequences are included within the draft genomes of various plant species, it is not entirely certain that these are not contaminants. The Nicotiana geminivirus-related DNA elements therefore remain the only definitively proven instances of endogenous plant ssDNA virus sequences. Here, we characterize two new classes of endogenous plant virus sequence that are also apparently derived from ancient geminiviruses in the genus Begomovirus. These two endogenous geminivirus-like elements (EGV1 and EGV2) are present in the Dioscorea spp. of the Enantiophyllum clade. We used fluorescence in situ hybridization to confirm that the EGV1 sequences are integrated in the D. alata genome and showed that one or two ancestral EGV sequences likely became integrated more than 1.4 million years ago during or before the diversification of the Asian and African Enantiophyllum Dioscorea spp. Unexpectedly, we found evidence of natural selection actively favouring the maintenance of EGV-expressed replication-associated protein (Rep) amino acid sequences, which clearly indicates that functional EGV Rep proteins were probably expressed for prolonged periods following endogenization. Further, the detection in D. alata of EGV gene transcripts, small 21-24 nt RNAs that are apparently derived from these transcripts, and expressed Rep proteins, provides evidence that some EGV genes are possibly still functionally expressed in at least some of the Enantiophyllum clade species.

Abstract
BACKGROUND Surface expression of stromal cell-derived factor-1 (SDF-1, CXCL12) on platelets is enhanced during ischemic events and plays an important role in peripheral homing of stem cells and myocardial repair mechanisms. SDF-1 effects are mediated through CXCR4 and CXCR7. Both CXCR4 and CXCR7 are surface expressed on human platelets and to a higher degree in patients with coronary artery disease (CAD) compared with healthy controls. In this study, we investigated the prognostic role of platelet CXCR4- and CXCR7 surface expression in patients with symptomatic CAD. METHODS AND RESULTS In a cohort study, platelet surface expression of CXCR4 and CXCR7 was measured by using flow cytometry in 284 patients with symptomatic CAD at the time of percutaneous coronary intervention (PCI). The primary combined end point was defined as all-cause death and/or myocardial infarction (MI) during 12-month follow-up. Secondary end points were defined as the single events of all-cause death and MI. We found significant differences of CXCR4 values in patients who developed a combined end point compared with event-free patients (mean MFIAUTHOR: Please define MFI at first use. 3.17 vs. 3.44, 95% confidence interval [CI] 0.09-0.45) and in patients who subsequently died (mean MFI 3.10 vs. 3.42, 95% CI 0.09-0.56). In multivariate Cox regression analysis, lower platelet CXCR4 levels were independently and significantly associated with all-cause mortality (hazard ratio 0.24, 95% CI 0.07-0.87) and the primary combined end point of all-cause death and/or MI (hazard ratio 0.30, 95% CI 0.13-0.72). CONCLUSION These findings highlight a potential prognostic value of platelet expression CXCR4 on clinical outcomes in patients with CAD.

Abstract
Tamoxifen is the standard-of-care treatment for estrogen receptor-positive premenopausal breast cancer. We examined tamoxifen metabolism via blood metabolite concentrations and germline variations of CYP3A5, CYP2C9, CYP2C19 and CYP2D6 in 587 premenopausal patients (Asians, Middle Eastern Arabs, Caucasian-UK; median age 39 years) and clinical outcome in 306 patients. N-desmethyltamoxifen (DM-Tam)/(Z)-endoxifen and CYP2D6 phenotype significantly correlated across ethnicities (R(2): 53%, P<10(-77)). CYP2C19 and CYP2C9 correlated with norendoxifen and (Z)-4-hydroxytamoxifen concentrations, respectively (P<0.001). DM-Tam was influenced by body mass index (P<0.001). Improved distant relapse-free survival (DRFS) was associated with decreasing DM-Tam/(Z)-endoxifen (P=0.036) and increasing CYP2D6 activity score (hazard ratio (HR)=0.62; 95% confidence interval (CI), 0.43-0.91; P=0.013). Low (<14 nM) compared with high (>35 nM) endoxifen concentrations were associated with shorter DRFS (univariate P=0.03; multivariate HR=1.94; 95% CI, 1.04-4.14; P=0.064). Our data indicate that endoxifen formation in premenopausal women depends on CYP2D6 irrespective of ethnicity. Low endoxifen concentration/formation and decreased CYP2D6 activity predict shorter DRFS.

Abstract
Etiological studies of a recently emerged bushy top disease of tobacco in Ethiopia indicated that a ~4.5-kb dsRNA from infected plants represents an umbravirus, whereas a smaller band (~0.5 kb) is that of a new satellite RNA. Potato leafroll virus was also consistently associated with the disease. The three agents, whose experimental host ranges are restricted to members of the family Solanaceae, always occurred together in field samples and are transmitted together by the aphid Myzus persicae nicotianae. The umbravirus, which represents a new species, is most closely related to groundnut rosette virus, and the name Ethiopian tobacco bushy top virus is proposed.

Abstract
Bemisia tabaci (Gennadius) is one of the economically most damaging insects to crops in tropical and subtropical regions. Severe damage is caused by feeding and more seriously by transmitting viruses. Those of the genus begomovirus (Geminiviridae) cause the most significant crop diseases and are transmitted by B. tabaci in a persistent circulative mode, a process which is largely unknown. To analyze the translocation and to identify critical determinants for transmission, two populations of B. tabaci MEAM1 were compared for transmitting Watermelon chlorotic stunt virus (WmCSV) and Tomato yellow leaf curl virus (TYLCV). Insect populations were chosen because of their high and respectively low virus transmission efficiency to compare uptake and translocation of virus through insects. Both populations harbored Rickettsia, Hamiltonella and Wolbachia in comparable ratios indicating that endosymbionts might not contribute to the different transmission rates. Quantification by qPCR revealed that WmCSV uptake and virus concentrations in midguts and primary salivary glands were generally higher than TYLCV due to higher virus contents of the source plants. Both viruses accumulated higher in insects from the efficiently compared to the poorly transmitting population. In the latter, virus translocation into the hemolymph was delayed and virus passage was impeded with limited numbers of viruses translocated. FISH analysis confirmed these results with similar virus distribution found in excised organs of both populations. No virus accumulation was found in the midgut lumen of the poor transmitter because of a restrained virus translocation. Results suggest that the poorly transmitting population comprised insects that lacked transmission competence. Those were selected to develop a population that lacks virus transmission. Investigations with insects lacking transmission showed that virus concentrations in midguts were reduced and only negligible virus amounts were found at the primary salivary glands indicating for a missing or modified receptor responsible for virus attachment or translocation.

Abstract
BACKGROUND Bemisia tabaci is a serious pest of agricultural and horticultural crops in greenhouses and fields around the world. This paper deals with the distribution of the pest under field conditions. In Europe, the insect is currently found in coastal regions of Mediterranean countries where it is subject to quarantine regulations. To assess the risk presented by B. tabaci to Europe, the area of potential establishment of this insect, in light of the climate change scenario, was assessed by a temperature-dependent physiologically based demographic model (PBDM). RESULTS The simulated potential distribution under current climate conditions has been successfully validated with the available field records of B. tabaci in Europe. Considering climate change scenarios of +1 and +2 °C, range expansion by B. tabaci is predicted, particularly in Spain, France, Italy, Greece and along the Adriatic coast of the Balkans. Nonetheless, even under the scenario of +2 °C, northern European countries are not likely to be at risk of B. tabaci establishment because of climatic limitations. CONCLUSION Model validation with field observations and evaluation of uncertainties associated with model parameter variability support the reliability of model results. The PBDM developed here can be applied to other organisms and offers significant advantages for assessing the potential distribution of invasive species.

Abstract
The genetic variation and population structure of Soybean mosaic virus (SMV) in Iran was analysed through the characterization of a set of isolates collected in the soybean-growing provinces of Iran. The partial nucleotide sequence of these isolates showed a single, undifferentiated population with low genetic diversity, highly differentiated from other SMV world populations. These traits are compatible with a population bottleneck associated with the recent introduction of SMV in Iran. Phylogenetic analyses suggest that SMV was introduced into Iran from East Asia, with at least three introduction events. The limited genetic diversification of SMV in Iran may be explained by strong negative selection in most viral genes eliminating the majority of mutations, together with recombination purging deleterious mutations. The pathogenicity of Iranian SMV isolates was typified on a set of soybean differential lines either susceptible or carrying different resistance genes or alleles to SMV. Two pathotypes were distinguished according to the ability to overcome Rsv4 resistance in line V94-5152. Amino acid sequence comparisons of virulent and avirulent isolates on V94-5152 (Rsv4), plus site-directed mutagenesis in a biologically active cDNA clone, identified mutation S1053N in the P3 protein as the determinant for virulence on V94-5152. Codon 1053 was shown to be under positive selection, and S1053N-determined Rsv4-virulence occurred in isolates with different genealogies. The V94-5152 (Rsv4)-virulence determinant in Iranian isolates maps into a different amino acid position in the P3 protein than those previously reported, indicating different evolutionary pathways towards resistance breaking that might be conditioned by sequence context.

Abstract
Yellowing diseases of field- and greenhouse-grown cucurbits are becoming increasingly important in many cucurbit cultivation areas in Iran. Virus surveys were conducted from 2011 to 2012 in greenhouse-grown cucumber (Cucumis sativus L.) and field-cultivated cucumber, squash (Cucurbita sp.) and melon (Cucumis melo L.) in Tehran, Semnan, Bushehr, Hormozgan, Isfahan, Yazd, and Fars provinces, the major cucurbit-growing areas in Iran. Leaf samples with various symptoms, e.g., chlorosis, interveinal chlorotic spots on lower leaves, bright yellow color or sever yellowing on older leaves, were collected and screened for the presence of the whitefly transmitted criniviruses (family Closteroviridae) Cucurbit chlorotic yellows virus (CCYV) and Cucurbit yellow stunting disorder virus (CYSDV) through double-antibody sandwich (DAS)-ELISA, using CCYV and CYSDV specific antisera (DSMZ, Germany). The ELISA results showed that of 347 cucumber leaf samples originating from cucumber greenhouses, 170 and 65 were positive for CCYV and CYSDV, respectively, and 45 samples were infected with both viruses. In addition, of 147 leaf samples collected from melon, cucumber, and squash grown in open fields, 57 and 53 were infected with CCYV and CYSDV, respectively, and 14 were infected with both viruses. These results indicate that these two viruses are widely distributed on these cucurbit crops in Iran. CCYV was not detected in Bushehr and CYSDV was not detected in Isfahan and Hormozgan provinces. To confirm the presence of CCYV and CYSDV, total RNA was extracted (Sigma Chemical, St. Louis, MO) from 18 samples that reacted positive in DAS-ELISA originating from different surveyed provinces. RT-PCR was carried out using specific primers Crini-s2 (5'-CATTCCTACCTGTTTAGCCA-3') (2) and Crini-as1 (5'-ATCCTTCGCAGTGAAAAACC-3') to amplify a 460-bp fragment of the HSP70 gene and CCYV using specific primers CCYV-HSP-F1 (5'-TGCGTATGTCAATGGTGTTATG-3') and CCYV-HSP-R1 (5'-ATCCTTCGCAGTGAAAAACC-3') to amplify a 462-bp fragment of the HSP70 gene (latter 3 primers from [3]). Expected DNA fragments for CYSDV and CCYV were amplified from 11 (CCYV 7/11, CYSDV 4/11) of 18 samples but not from any of the healthy controls. Further analysis by sequencing three selected PCR products amplified with primers CCYV-HSP-F1/R1 showed complete consensus among the sequences, and in comparison with sequences available at GenBank, the highest identities were obtained to Asian CCYV isolates (94% nt/98% aa identity). The CCYV sequences were deposited in GenBank under accessions KC559449 to KC559451. The identity of the amplified CYSDV DNA could also be confirmed by sequencing of three PCR products. CCYV has first been proven to occur in different countries in East Asia and has recently been reported from Sudan (2) and Lebanon (1), indicating the putative spread of the virus wherever cucurbits are grown and its vector, the whitefly Bemisia tabaci, is present. Large populations of whiteflies were present in all surveyed areas. However, to our knowledge, this is the first report for the occurrence of CCYV in Iran. In conclusion, the presence of CCYV and CYSDV in the major cucurbit growing provinces and the large whitefly population pose a serious threat to cucurbit production in Iran. References: (1) P. E.

Abstract
Garlic (Allium sativum L.) is one of the most important vegetable field crops in Sudan, cultivated on an area of more than 6,000 ha with a total yield of 27,000 t in 2010 (faostat.fao.org). As part of a project which started in 2010 to improve the garlic production in Sudan, samples from local varieties showing severe mosaic and/or mottling were collected in winter 2011 from the main production areas in River Nile State, Northern State, and Darfur State. The plant material used for garlic production came from Sudan and was not imported. Because no reliable data were available on which viruses occur in garlic in Sudan, specific tests were initially omitted. In order to get an overview of the viruses present, dsRNA was prepared of a mixed leaf sample (12 leaves of different samples). This resulted in a high molecular weight dsRNA of approximately 9 kbp that served as template for a random RT-PCR followed by cloning and sequencing (3). Three identical clones originating from one PCR product covering the C-terminal part of the coat protein to the N-terminal part of the nucleic acid binding protein showed the highest sequence similarity to Garlic common latent virus (GarCLV). The nucleotide sequence identities of the 554-bp insert range from 85% to an isolate from India (Accession No. FJ154841) up to 97% to a GarCLV isolate from The Netherlands (AB004804), identifying the virus as a Sudanese isolate of GarCLV, one of the most common garlic infecting viruses. GarCLV belongs to the genus Carlavirus (1) and has previously been reported from Asia, Europe, and South America ( http://sdb.im.ac.cn/vide/descr352.htm ). In order to confirm these results, a double antibody sandwich (DAS)-ELISA was performed with six individual garlic samples in which five samples showed a clear reaction with a GarCLV specific antiserum (AS-0230, DSMZ, Germany). The occurrence of GarCLV could be further confirmed for the ELISA positive samples by a specific RT-PCR using the primers published by Majumder and Baranwal (2). Fragments of the expected size were obtained for all five samples. In addition, one of the positive samples was examined by electron microscopy (Dr. K. Richert-Pöggeler, JKI Braunschweig); filamentous flexous particles typical for carlaviruses could be observed. The random RT-PCR sequence obtained in this study has been submitted to GenBank (KC013030). To our knowledge, this is the first report of GarCLV in garlic in Sudan and Africa. The impact of GarCLV on garlic production in Sudan needs to be evaluated, but the awareness of the occurrence of the virus and the availability of a reliable diagnostic tool will help to select virus-free propagation material. This will form the basis for a sustainable garlic production. References: (1) A. M. Q. King et al. Virus Taxonomy 924, 2012. (2) S. Majumder and V. K. Baranwal. Plant Dis. 93:106, 2009. (3) W.
