Tobacco vein mottling virus (TVMV) is a member of the Potyviridae, one of the largest families of plant viruses. The TVMV genome is translated into a single large polyprotein that is subsequently processed by three virally encoded proteases. Seven of the nine cleavage events are carried out by the NIa protease. Its homolog from the tobacco etch virus (TEV) is a widely used reagent for the remov...

The effect of tobacco etch virus (TEV) (Genus: Potyvirus, Family: Potyviridae) on growth and yield of Capsicum chinense Jacquin cv. ‘Scotch Bonnet’ and ‘West Indian Red’ peppers was investigated. Peppers were manually inoculated at 7, 28 and 56-57 days after transplanting (DAT), which corresponded with early vegetative stage, onset of flowering and completion of first stage of flowering, respec...

Field surveys to collect isolates of Bean pod mottle virus (BPMV), a member of the genus Comovirus, were done in 1997, 1998 and 2001 in research centers and growers’ commercial fields in Virginia. The isolates were collected by taking leaves from symptomatic plants and confirming the presence of virus using leaf blot immunoassay, followed by propagation of selected positive samples in the green...

Among 67 or so viruses that are able to infect soybean, 27 are considered a threat to the soybean industry (Tolin and Lacy, 2004; Saghai Maroof et al., 2008). Soybean mosaic virus (SMV) is the most prevalent virus and is recognized as the most serious, long-standing problem in many soybean producing areas in the world (Wang, 2009). SMV is a member of the genus Potyvirus in the family Potyvirida...

Iris is an important ornamental and medicinal plant, grown commercially for floriculture domestically aesthetic value. Ornithogalum mosaic virus (OrMV, Potyviridae) has a broad host range infecting plants of the genera Diuris, Gladiolus, (Gao et al., 2018). During April 2020, symptoms mosaics chlorotic spots on leaves were observed in versicolor growing Mashhad city, northeast Iran (Fig. 1). Yo...
