Virgaviridae is a family of positive single stranded RNA viruses that infect plants.[1] All virons in this family are rod shaped. There are currently six genera in this family.
The name of the family is derived from the Latin word virga (rod).
Characteristics
- Alpha-like replication proteins that form a distinct phylogenetic family.
- Single-stranded RNA positive sense genomes with a 3'-tRNA like structure and no polyA tail.
- Rod-shaped virions 20–25 nm in diameter with a central 'canal'
- Coat proteins of 19–24 kiloDaltons
The virons in this family are non-enveloped, rigid helical rods with a helical symmetry, and about 20–25 nanometres in diameter with a central 'canal'. Depending on the genus the genome may be in one, two or three segments.
Notes
The genus Benyvirus although rod shaped and infecting plants is not included in this family as its proteins appear to be only very distantly related to the genera in this family
