Genus

Genus: Rosadnavirus

Family: Caulimoviridae

Genus: Rosadnavirus

 

Distinguishing features 

Rose yellow vein virus (RYVV) is distinguishable from all other members of the Caulimoviridae by its unique genome organization, in having overlapping ORFs 1, 2 and 3, a very large genome and in its phylogenetic placement based upon analysis of polymerase gene sequences.

Virion

Morphology

Virions of RYVV are icosahedral, 42–45 nm in diameter. 

Genus

Genus: Petuvirus

Family: Caulimoviridae

Genus: Petuvirus

 

Distinguishing features

Petunia vein clearing virus (PVCV), a member of the sole species in the genus, Petuvirus venapetuniae, is distinguishable from all other members of the Caulimoviridae except for vacciniviruses by its simple genome organization (one ORF) and phylogenetic placement based upon analysis of polymerase gene sequences.
