Genus: Cardiovirus
Family: Picornaviridae
Genus: Cardiovirus
Genus: Avihepatovirus
Family: Picornaviridae
Genus: Avihepatovirus
Distinguishing features
The genus is distinguished on the basis of genetic characters.
Virion
Morphology
No surface morphology is visible by EM.
Physicochemical and physical properties
Avihepatoviruses are both heat and acid stable.
Genus: Aquamavirus
Family: Picornaviridae
Genus: Aquamavirus
Distinguishing features

No details are available on physicochemical and physical properties.
Genus: Ampivirus
Family: Picornaviridae
Genus: Ampivirus
Distinguishing features
The genus is distinguished on the basis of genetic characters. The known ampiviruses have rather large protease and polymerase proteins compared to those of other picornaviruses.

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.
Genus: Pecluvirus
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.
Genus: Hordeivirus
Family: Virgaviridae
Genus: Hordeivirus
Distinguishing features
Hordeiviruses have three genomic RNAs and encode a “triple gene block” set of cell-to-cell movement proteins. They differ from viruses of all other genera because the RdRP is encoded on a separate RNA (rather than by readthrough of a stop codon from an upstream replication protein encoding ORF).
