Genus: Tobravirus
Family: Virgaviridae
Genus: Tobravirus
Distinguishing features
Tobraviruses have a bipartite genome, a “30K”-like cell-to-cell movement protein and are transmitted by trichodorid nematodes.
Genus: Tobamovirus
Family: Virgaviridae
Genus: Tobamovirus
Genus: Pomovirus
Family: Virgaviridae
Genus: Pomovirus
Distinguishing features
Pomoviruses have three genomic RNAs, a “triple gene block” set of cell-to-cell movement proteins and are transmitted by root-infecting vectors in the family Plasmodiophorales, once described as fungi but now classified as Cercozoa.

Family: Virgaviridae
Genus: Pecluvirus
Distinguishing features
Pecluviruses have a bipartite genome, a “triple gene block” set of cell-to-cell movement proteins and are transmitted by root-infecting vectors in the family Plasmodiphorales, once described as fungi but now classified as Cercozoa.
