Orthotospovirus arachianuli
Assigned virus:
• groundnut ringspot virus (GRSV)
The groundnut ringspot virus infects groundnuts, tomatoes and various other plants in the Americas and Africa. Symptoms on groundnut are stunting, smaller and distorted leaves and ringspots. On tomatoes and pepper they have been mainly described as chlorosis, mosaic, ringspots and stem necrosis. The virus can be transmitted by several species of thrips in a circulative-propagative manner. These include Frankliniella occidentalis and F. schultzei.
The genomes of GRSV consists of three RNA segments named small (S), medium (M), and large (L). The RNA of the S segment encodes a nucleocapsid protein and a silencing suppressor protein. The RNA of the M segment encodes a precursor for two glycoproteins and a movement protein. The RNA of the L segment encodes a multifunction protein, with an RNA-dependent RNA polymerase domain.
