RNA silencing suppressor activity of Velvet bean severe mosaic begomovirus DNA-A encoded proteins
Archives of Phytopathology and Plant Protection 50 (7-8), 341-348
Abstract: Velvet bean severe mosaic virus (VbSMV) is a bipartite DNA virus infecting Mucuna pruriens (Velvet bean), belongs to the genus Begomovirus in the family Geminiviridae. Velvet bean is a medicinal plant of enormous medicinal value. In the present study, it was delineated that proteins encoded by VbSMV viz. AV2 (pre-coat protein), AC2 (TrAP), AV1 (coat protein) are suppressors of RNA silencing as identified through Agrobacterium co-infiltration assays using Nicotiana benthamiana as a host plant. AV2 showed strong suppressor activity whereas AC1 and AV1 were found to be weak suppressors. To the best of our knowledge, this is the first report on identification of suppressor of RNA silencing encoded by VbSMV infecting a medicinal plant.
