The nucleotide sequence (5966 nucleotides) of cDNA clones of strawberry mild yellow edge-associated potexvirus was determined. The genome contains six open reading frames (ORFs) encoding putative proteins with Mrs of 149,423, 25,344, 11,576, 8079, 25,714 and 11,216. In the first three putative proteins and the coat protein considerable similarity was found to comparable polypeptides of the pote...

Viral attacks on natural populations of herbaceous forage legumes might have adverse effect on seed and herbage production, hence this study was carried out to investigate the type and incidence of viruses occurring on these plants in Nigeria. Protein A-sandwich (PAS) and antigen-coated plate (ACP) enzyme-linked immunosorbent assays (ELISA) were used to detect ten legume viruses from 100 leaf s...

Mixed viral infections in plants involving a potyvirus and other unrelated virus often result synergistic effects, with significant increases accumulation of the non-potyvirus partner, as case melon infected by Watermelon mosaic (WMV) crinivirus Cucurbit yellow stunting disorder (CYSDV). To further explore interaction between these two viruses, activity RNA silencing suppressors (RSSs) was addr...

It is well described that viral infections stimulate the emission of plant volatiles able to recruit vectors thereby promoting virus spread. In contrast, much less known on effects emitted may have metabolism healthy neighboring plants, which are potential targets for new through vector transmission. Watermelon mosaic (WMV) (genus Potyvirus, family Potyviridae) an aphid-transmitted endemic in c...

introduction: several potyviruses infecting gramineous plants have been reported from iran. mosaic is the most widespread viral disease affecting sugarcane and maize production. sugarcane mosaic virus (scmv) is one of the causal agents of mosaic disease, which was first described in ohio in 1963. scmv belonging to the genus potyvirus, family potyviridae, is a single-stranded positive sense rna ...

in recent years, symptoms of virus diseases on stone fruits have been observed in wide range in golestan province. in order to study the important viruses on stone fruits, cherry, plum, nectarine, peach and apricot trees with symptoms such as mosaic, chlorosis, ring spot, shot hole, pale margins in leaves and dwarf in trees, sampling was done during 2005. putative infected plants were tested by...

ABSTRACT A novel whitefly-transmitted member of the family Potyviridae was isolated from a squash plant (Cucurbita pepo) with vein yellowing symptoms in Florida. The virus, for which the name Squash vein yellowing virus (SqVYV) is proposed, has flexuous rod-shaped particles of approximately 840 nm in length. The experimental host range was limited to species in the family Cucurbitaceae, with th...

In order to assess the occurrence, distribution and importance of viral diseases of mungbean and mashbean crops in Punjab, Pakistan, an extensive survey was conducted during summer season of 2004. The symptomatic plant samples were collected from farmer’s fields and experimental plots at research stations and tested by Enzyme-linked Immunosorbent Assay (ELISA) to detect and identify viruses inf...
