General Description

This family is characterised by enveloped spherical virions 60-70 nm in diameter and a single component of single-stranded RNA, which has a polyA tail. The RNA encodes two polyproteins that are subsequently processed into a number of structural and non-structural proteins.

Morphology

Virions enveloped and spherical 60-70 nm in diameter, with glycoprotein spikes.

Genome

Monopartite positive sense single-stranded RNA of about 9-12kb with a 5' cap and a 3'-polyA tail. The RNA encodes two polyproteins that are subsequently processed into a number of structural and non-structural proteins. The 3'- (structural) ORF is translated from a subgenomic RNA.
