Tomato brown rugose fruit virus (ToBRFV) causes severe crop losses worldwide, infecting primarily tomato (Solanum lycopersicum) and pepper (Capsicum annuum). It was detected for the first time in 2014 Israel (Luria et al., 2017), then 2015 Jordan (Salem 2016), has since spread rapidly to other countries. In Americas, it reported Mexico (Cambrón-Crisantos 2018) USA (Ling 2019). December 2022, gr...

The 2b protein encoded by cucumber mosaic cucumovirus (Cmv2b) acts as an important virulence determinant by suppressing post-transcriptional gene silencing (PTGS), a natural plant defence mechanism against viruses. We report here that the tomato aspermy cucumovirus 2b protein (Tav2b), when expressed from the unrelated tobacco mosaic tobamovirus (TMV) RNA genome, activates strong host resistance...

The Tm-2(2) resistance gene is used in most commercial tomato cultivars for protection against infection with tobacco mosaic virus and its close relative tomato mosaic virus (ToMV). To study the mechanism of this resistance gene, cDNA clones encompassing the complete genome of a ToMV strain (ToMV-2(2)) that was able to break the Tm-2(2) resistance were generated. Chimeric full-length viral cDNA...

We present here the first complete genome sequence of the tobamovirus Cucumber green mottle mosaic virus (CGMMV) from Australia, obtained from an infected cucumber plant. Compared with other CGMMV genomes, its closest nucleotide identities were 99.6% to KP772568, 99.3% to KF155229, and 99.1% to DQ767631 from Canada, Israel, and India, respectively.

In August 2021, symptoms of a viral-like infection were observed on the leaves and fruits tomato plants, cvs. Emperador RZF1 (Rijk Zwaan, The Netherlands) Maxifort, Eshkol 4129 (Seminis Vegetable Seeds, USA) in 3.2 ha greenhouse complex Isfahan province, Iran. Plants had been raised Iran from imported seed. consisted severe mosaic deformation (especially upper young leaves) chlorotic brown necr...

Pepper mild mottle virus (PMMoV) is a plant belonging to the Virgaviridae family; it significantly reduces pepper yield production worldwide. The PMMoV spread by contaminated seeds and there no chemical treatment available. Therefore, resistant varieties containing L4 gene are recommended for management of PMMoV. A considerable amount evidence suggests that confers resistance in pepper. aim pro...

Due to considerable losses in the agricultural sector, phytopathogenic viruses are of significant economic importance. Several have been detected water bodies. These can be transmitted their hosts through contact. However, relatively few studies concentrate on presence and impact plant-infecting environments. In present study, we used a metagenomic approach determine viral phytopathogen diversi...
