Abstract
Unlike many segmented negative-sense RNA viruses, most members of the Bunyavirales bud at Golgi membranes, as opposed to the plasma membrane. Central players in this assembly process are the envelope glycoproteins, Gn and Gc, which upon translation undergo proteolytic processing, glycosylation and trafficking to the Golgi, where they interact with ribonucleoprotein genome segments and bud into Golgi-derived compartments. The processes involved in genome packaging during virion assembly can lead to the generation of reassorted viruses, if a cell is co-infected with two different bunyaviruses, due to mismatching of viral genome segment packaging. This can lead to viruses with high pathogenic potential, as demonstrated by the emergence of Schmallenberg virus. This review focuses on the assembly pathways of tri-segmented bunyaviruses, highlighting some areas in need of further research to understand these important pathogens with zoonotic potential.

Abstract
Aphids are insect vectors that have piercing-sucking mouthparts supporting diversified patterns of virus-vector interactions. Aphids primarily retain circulative viruses in the midgut/hindgut, whereas noncirculative viruses tend to be retained in the stylet. Most viruses, and many proteins from animals, have carbohydrate or carbohydrate-binding sites. Lectins vary in their specificity, of which some are able to bind to viral glycoproteins. To assess the potential competition between lectins and viral particles in virus transmission by aphids, this study examined how feeding plant lectins to aphids affects the transmission efficiency of viruses. Sitobion avenae (F, 1794) (Homoptera: Aphididae) aphids fed with Pisum sativum lectin (PSL) transmitted Barley yellow dwarf virus with significantly lower efficiency (four-fold ratio). Pea enation mosaic virus was significantly reduced in Acyrthosiphon pisum Harris (Homoptera: Aphididae) aphids fed with the lectin Concanavalin A. In comparison, the transmission of Potato virus Y was significantly reduced when Myzus persicae Sultzer (Homoptera: Aphididae) aphids were fed with PSL. Thus, lectin could be used as a blocking agent of plant viruses, facilitating an alternative approach for crop protection.

Abstract
IgE plays a key role in allergies by binding to allergens and then sensitizing mast cells through the Fc receptor, resulting in the secretion of proinflammatory mediators. Therefore, IgE is a major target for managing allergies. Previous studies have reported that oligomannose on IgE can be a potential target to inhibit allergic responses. However, enzymes that can modulate IgE activity are not yet known. Here, we found that the commercial receptor-destroying enzyme (RDE) (II) from Vibrio cholerae culture fluid specifically modulates IgE, but not IgG, and prevents the initiation of anaphylaxis. RDE (II)-treated IgE cannot access its binding site on bone marrow-derived mast cells, resulting in reduced release of histamine and cytokines. We also noted that RDE (II)-treated IgE could not induce passive cutaneous anaphylaxis in mouse ears. Taken together, we concluded that RDE (II) modulates the IgE structure and renders it unable to mediate allergic responses. To reveal the mechanism by which RDE (II) interferes with IgE activity, we performed lectin microarray analysis to unravel the relationship between IgE modulation and glycosylation. We observed that RDE (II) treatment significantly reduced the binding of IgE to Lycopersicon esculentum lectin, which recognizes poly-N-acetylglucosamine and poly-N-acetyllactosamine. These results suggest that RDE (II) specifically modulates branched glycans on IgE, thereby interfering with its ability to induce allergic responses. Our findings may provide a basis for the development of drugs to inhibit IgE activity in allergies.

Abstract
Lettuce (Lactuca sativa L.) production in coastal California, one of the major lettuce-producing areas of the United States, is regularly affected by outbreaks of Impatiens necrotic spot virus (INSV), a member of the genus Orthotospovirus. Transmission of INSV among lettuce crops in this growing region has been attributed predominantly to the western flower thrips (Frankliniella occidentalis). INSV is acquired by first- or second-instar thrips nymphs feeding on infected host plants (not necessarily lettuce). The virus replicates within the insect vector, and is transmitted to new plants by adult thrips as they feed on epidermal and mesophyll cells of susceptible host plants. All currently grown cultivars of lettuce are susceptible to the disease. Screening lettuce for resistance to INSV under field conditions is problematic because natural infections appear sporadically and the virus is not evenly distributed across infected fields. We have developed a greenhouse-based assay that uses viruliferous thrips in combination with mechanical inoculation that allows dependable, year-round screening for resistance. In all, 89 cultivars, breeding lines, and plant introductions of cultivated lettuce, together with 53 accessions from 11 other Lactuca spp., 4 accessions from two dandelion (Taraxacum) species, and 4 tomato (Solanum lycopersicum L.) lines were evaluated for resistance to INSV. All tested material was susceptible to INSV to varying degrees, with the exception of two tomato lines that carry the Sw-5 gene that confers resistance to Tomato spotted wilt virus, a virus closely related to INSV. In cultivated lettuce, a partial resistance to INSV was observed in cultivars Amazona, Ancora, Antigua, Commodore, Eruption, Iceberg, La Brillante, Merlot, Telluride, and Tinto. Limited comparison of the greenhouse-based screening results with the data from opportunistic evaluations of resistance on 775 lettuce accessions from six field trials indicates consistency of results from both greenhouse and field environments. The most resistant lettuce accessions are being incorporated into our breeding program for introgression of resistance into lettuce breeding lines.

Abstract
Vector-borne viruses are a threat to human, animal, and plant health worldwide, requiring the development of novel strategies for their control. Tomato spotted wilt virus (TSWV) is one of the 10 most economically significant plant viruses and, together with other tospoviruses, is a threat to global food security. TSWV is transmitted by thrips, including the western flower thrips, Frankliniella occidentalis. Previously, we demonstrated that the TSWV glycoprotein GN binds to thrips vector midguts. We report here the development of transgenic plants that interfere with TSWV acquisition and transmission by the insect vector. Tomato plants expressing GN-S protein supported virus accumulation and symptom expression comparable with nontransgenic plants. However, virus titers in larval insects exposed to the infected transgenic plants were three-log lower than insects exposed to infected nontransgenic control plants. The negative effect of the GN-S transgenics on insect virus titers persisted to adulthood, as shown by four-log lower virus titers in adults and an average reduction of 87% in transmission efficiencies. These results demonstrate that an initial reduction in virus infection of the insect can result in a significant decrease in virus titer and transmission over the lifespan of the vector, supportive of a dose-dependent relationship in the virus-vector interaction. These findings demonstrate that plant expression of a viral protein can be an effective way to block virus transmission by insect vectors.

A reinvestigation provides no evidence for sugar residues on structural proteins of poleroviruses and argues against a role for glycosylation of virus structural proteins in aphid transmission.

Abstract
Poleroviruses are strictly transmitted by aphids. Glycosylation of Turnip yellows virus (TuYV) was previously reported and this modification was supposed to be required for aphid transmission. Using different approaches based on (i) a lectin-binding assay, (ii) use of specific complex glycan antibodies and (iii) mass spectrometry, we found no evidence that the structural proteins of TuYV and Cucurbit aphid-borne yellow virus (CABYV) carry glycan residues. Moreover, mutation of each of the four potential N-glycosylation sites of the structural protein sequences of CABYV indicated that, unless more than one site on the structural protein is glycosylated, N-glycosylation is not involved in aphid transmission. These results did not corroborate the previous hypothesis for the role of glycosylation in aphid transmission. They, however, revealed the presence of a glycosylated plant protein in purified polerovirus suspensions, whose function in aphid transmission should be further investigated.

Abstract
A biological attack on U.S. crops, rangelands, or forests could reduce yield and quality, erode consumer confidence, affect economic health and the environment, and possibly impact human nutrition and international relations. Preparedness for a crop bioterror event requires a strong national security plan that includes steps for microbial forensics and criminal attribution. However, U.S. crop producers, consultants, and agricultural scientists have traditionally focused primarily on strategies for prevention and management of diseases introduced naturally or unintentionally rather than on responding appropriately to an intentional pathogen introduction. We assess currently available information, technologies, and resources that were developed originally to ensure plant health but also could be utilized for postintroduction plant pathogen forensics. Recommendations for prioritization of efforts and resource expenditures needed to enhance our plant pathogen forensics capabilities are presented.

Abstract
The complete nucleotide sequence of a tospovirus isolated from Lycopersicum esculentum in Thailand was determined. The L RNA comprises of 8912 nt and codes for the RNA-dependent RNA-polymerase (RdRp) (2877 aa). Two ORFs are located on the M RNA (4823 nt) encoding the non-structural (NSm) protein (308 aa) and the viral glycoprotein precursors (Gn/Gc) (1121 aa) separated by an intergenic region of 433 nt. ORFs coding for the non-structural (NSs) and nucleocapsid (N) protein, 439 aa and 275 aa, respectively, were identified on the S RNA (3477 nt) separated by an intergenic region of 1202 nt. The N protein of the Thailand isolate was most closely related to that of capsicum chlorosis virus (CaCV), sharing an amino acid sequence identity of 92.7%. Additionally, multiple sequence analyses revealed significant similarities to tospoviruses of the species Watermelon silver mottle virus and to several putative tospovirus entries in GenBank. Based on these alignments it is proposed to refer to all these different viruses as isolates of CaCV.

Abstract
Beet western yellows virus relies on the aphid M. persicae for its transmission in a persistent and circulative mode. To be transmitted, the virus must cross the midgut and the accessory salivary gland epithelial barriers by a transcytosis mechanism where vector receptors interact with virions. The aphid and the peptidic viral determinants implicated in this interaction mechanism have been studied. In this paper, we report that the coat and the readthrough proteins that constitute the capsid of this virus are glycosylated. Modification of the glucidic core of these structural viral proteins by oxidation with sodium metaperiodate or deglycosylation with N-glycosidase F or alpha-D-galactosidase abrogates the aphid transmission of the virus. Aphid transmission could also be inhibited by lectins directed against alpha-D-galactose when aphids were allowed to acquire virus on artificial membranes. These results suggest that the glucidic cores of the capsid proteins of beet western yellows virus contain alpha-D-galactose residues that are implicated in virus-aphid interaction and promote aphid transmission of the virus.

Abstract
The complex and specific interplay between thrips, tospoviruses, and their shared plant hosts leads to outbreaks of crop disease epidemics of economic and social importance. The precise details of the processes underpinning the vector-virus-host interaction and their coordinated evolution increase our understanding of the general principles underlying pathogen transmission by insects, which in turn can be exploited to develop sustainable strategies for controlling the spread of the virus through plant populations. In this review, we focus primarily on recent progress toward understanding the biological processes and molecular interactions involved in the acquisition and transmission of Tospoviruses by their thrips vectors.

Abstract
Tomato spotted wilt virus (TSWV), a member of the Tospovirus genus within the Bunyaviridae, is an economically important plant pathogen with a worldwide distribution. TSWV is transmitted to plants via thrips (Thysanoptera: Thripidae), which transmit the virus in a persistent propagative manner. The envelope glycoproteins, G(N) and G(C), are critical for the infection of thrips, but they are not required for the initial infection of plants. Thus, it is assumed that the envelope glycoproteins play important roles in the entry of TSWV into the insect midgut, the first site of infection. To directly test the hypothesis that G(N) plays a role in TSWV acquisition by thrips, we expressed and purified a soluble, recombinant form of the G(N) protein (G(N)-S). The expression of G(N)-S allowed us to examine the function of G(N) in the absence of other viral proteins. We detected specific binding to thrips midguts when purified G(N)-S was fed to thrips in an in vivo binding assay. The TSWV nucleocapsid protein and human cytomegalovirus glycoprotein B did not bind to thrips midguts, indicating that the G(N)-S-thrips midgut interaction is specific. TSWV acquisition inhibition assays revealed that thrips that were concomitantly fed purified TSWV and G(N)-S had reduced amounts of virus in their midguts compared to thrips that were fed TSWV only. Our findings that G(N)-S binds to larval thrips guts and decreases TSWV acquisition provide evidence that G(N) may serve as a viral ligand that mediates the attachment of TSWV to receptors displayed on the epithelial cells of the thrips midgut.
