Tomato ringspot virus (ToRSV)
The virus is wide-spread and infects a large variety of vegetables, fruit trees and other crops like grapevine. It can be economically important in some regions, e.g. on fruit trees. Symptoms depend on the host plant and include stunting, chlorotic ringspots, mosaic, leaf curling, stem pitting and necrosis.
The virus can be transmitted easily mechanically (e.g. through grafting), by nematodes of the genus Xiphinema, pollen and through seeds. The use of resistant cultivars and virus-free plant materials are the recommended control methods.
The virus has a single-stranded RNA genome and isometric particles, about 28 nm in diameter. It belongs to subgroup C of the nepoviruses. This subgroup is characterized by a large RNA2 (around 6,500-7,000 nt) and an untranslated 3' end of about 1,500 nt.
