Order: Martellivirales
Family: Virgaviridae
Genus: Tobamovirus

Tobamovirus is a genus of positive-strand RNA viruses[2] in the family Virgaviridae.[3] Many plants,[2] including tobacco, potato, tomato, and squash, serve as natural hosts. Diseases associated with this genus include: necrotic lesions on leaves.[3][4] The name Tobamovirus comes from the host and symptoms of the first virus discovered (Tobacco mosaic virus).[5]

There are four informal subgroups within this genus: these are the tobamoviruses that infect the brassicas, cucurbits, malvaceous, and solanaceous plants. The main differences between these groups are genome sequences, and respective range of host plants.[citation needed] There are 37 species in this genus.[6]
