Diagnostic of 12 viral pathogens stone fruit crops, including new to the certification scheme ( Carnation ringspot tombusvirus (CRSV), Myrobalan latent nepovirus (MLRSV), Petunia asteroid mosaic (PeAMV) , Tobacco (TRSV )) by immune-enzyme analysis was carried out in Institute for growing 2020 – 2021. Virus-free clones varieties and rootstocks forms crops have been identified create Nuclear stoc...
Physical properties of capsids of plant and animal viruses are important factors in capsid self-assembly, survival of viruses in the extracellular environment, and their cell infectivity. Combined AFM experiments and computational modeling on subsecond timescales of the indentation nanomechanics of Cowpea Chlorotic Mottle Virus capsid show that the capsid's physical properties are dynamic and l...
A novel concept for the assay of viral antigens is described. The methodological approach is based on a membrane-engineering process involving the electroinsertion of virus-specific antibodies in the membranes of fibroblast cells. As a representative example, Vero fibroblasts were engineered with antibodies against Cucumber mosaic virus (CMV) and used for the construction of an ultra-sensitive ...
The X-ray crystal structure of Cowpea chlorotic mottle bromovirus (CCMV) revealed a unique tubular structure formed by the interaction of the N-termini from six coat protein subunits at each three-fold axis of the assembled virion. This structure, termed the beta-hexamer, consists of six short beta-strands. The beta-hexamer was postulated to play a critical role in the assembly and stability of...
Carnation small viroid-like RNA (CarSV RNA) and its homologous DNA are the two forms of a unique plant retroviroid-like system. CarSV RNA is a 275-nucleotide noninfectious viroid-like RNA, present in certain carnation plants, which can adopt hammerhead structures in both polarity strands and self-cleave accordingly. CarSV DNA is organized as a series of head-to-tail multimers forming part of ex...
In vitro assembly of tobacco mosaic virus (TMV) from its constituent RNA and protein occurs in two steps: formation of the initial complex by interaction of the 5'-end of TMV-RNA with 20S protein aggregate, and growth of the helical rod by sequential addition of protein subunits.Such a process was also observed in the assembly of cucumber green mottle mosaic virus, which is also a rodshaped vir...
Plants including pepper, red kidney bean, squash, string bean and tomato, as well as weeds with viral symptoms were collected from five districts in Belize over a three year period with the aim of determining the diversity of the begomoviruses present. Sixty five percent of the samples screened via DNA hybridization produced signals indicative of begomovirus infection. Subsequent PCR amplificat...
Potyviruses are one of the most destructive viral pathogens of Solanaceae plants. In Capsicum annuum landrace CM334, a broad-spectrum gene, Pvr4 is known to be involved in resistance against multiple potyviruses, including Pepper mottle virus (PepMoV), Pepper severe mosaic virus (PepSMV), and Potato virus Y (PVY). However, a potyvirus avirulence factor against Pvr4 has not been identified. To i...
Backtrap mottle is a common printing defect that is difficult to correct. A good understanding of the mechanisms that leads to backtrap mottle is still lacking in the literature. A confocal laser scanning microscopy (CLSM) is used to evaluate samples that had different tendencies towards backtrap mottle. The coating structure is observed by staining the coating with a fluorescence dye. The fina...
