Genus: Hemipivirus

Genus: Hemipivirus

Distinguishing features

The genus is distinguished on the basis of genetic characters.

Virion

Morphology

No details are available on the morphology of virions.

Nucleic acid

Genome (Shi et al., 2018): c. 7,969 nt (5′-UTR: 466 nt; ORF: 7,398 nt; 3'-UTR: 105 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:

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

The deduced polyprotein is of 2,466 amino acids. There is an L protein with unknown function. The 1AB protein remains uncleaved. The 2A protein has an H-box/NC sequence motif.

Biology

No virus has been isolated. Viral RNA was detected in organ pools (gut, liver, lungs) of oriental leaf-toed geckos (Hemidactylus bowringii).

Derivation of names

Hemipivirus: derived from Hemidactylus bowringii (host) and picornavirus
