General Description

This family is characterised icosahedral virions about 30 nm in diameter and a single component of single-stranded C-rich RNA. The RNA encodes a large replication protein and a coat protein translated from a 3'-coterminal subgenomic RNA. There are additional ORFs in some genera.

Morphology

Virions isometric and icosahedral (T=3), not enveloped, about 30 nm in diameter.

Genome

Monopartite positive sense single-stranded RNA of about 6-7.5 kb. The RNA encodes a large replication protein and a coat protein translated from a 3'-coterminal subgenomic RNA. The 3'-terminus may have a tRNA-like structure or a polyA tract, depending upon the virus.
