Virion

Nucleic acid

Length of genome (Boros et al., 2013): c. 7,272 nt (5'-UTR: 500 nt; ORF: 6,747 nt; 3'-UTR: 25 nt). 5' UTR contains a type IV-B IRES. The 3' UTR is the shortest of picornaviruses, at 25 nt. The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5'UTR^IRES-IVB[1AB-1C-1D-2A1^NPGP/2A2-2B-2C/3A-3B-3C-3D]3'UTR-poly(A)

The deduced polyprotein has a length of 2,248 amino acids. There is no L protein. 1AB remains uncleaved. 2A1 is a short FMDV typeA-like polypeptide (NPG¯P), 2A2 protein has unknown function.

Biology

Viral RNA was detected in faeces of an apparently healthy European roller (Coracias garrulus). 

Species demarcation criteria

Members of a species of the genus Kunsagivirus share a common genome organization.
