Genus: Pemapivirus

Genus: Pemapivirus

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 (Shi et al., 2018): c. 9,196 nt (5′-UTR: 668 nt; ORF: 8,235 nt; 3′-UTR: 293 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 2,745 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 Chinese softshell turtles (Pelodiscus sinensis) and Chinese broad-headed pond turtles (Mauremys megalocephala).

Derivation of names

Pemapivirus: derived from Pelodiscus sinensis and Mauremys megalocephala (hosts) and picornavirus
