Genus: Poecivirus


Genus: Poecivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.

Virion

Morphology

No details are available on the morphology of the virions.

Nucleic acid

Genome (Zylberberg et al., 2016): 7,653 nt (5′UTR: 788 nt; ORF: 6,780 nt; 3′UTR: 85 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:

VPg+5′-UTR-[1AB-1C-1D/2A-2B-2C/3A-3B-3C-3D]-3′-UTR-poly(A)

The deduced polyprotein is of 2,260 aa. The genome encodes no L protein. 1AB remains uncleaved. The function of the 2A protein is unknown.

Antigenicity

See discussion under family description.

Biology

Viral RNA has been detected in tissue samples (mandible) of diseased black-capped chickadees (Poecile atricapillus) in Anchorage and the Matanuska-Sustna Valley, Alaska, USA. The virus is suspected to cause the avian keratin disorder (AKD).
