Genus: Gruhelivirus

Genus: Gruhelivirus

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Genome (S. Yang, Y. Wang, W. Zhang, unpublished): c. 7,073 nt (5′-UTR: 609 nt; ORF: 6,462 nt). The location of the cre has not been identified.

Genome organization and replication

Genome layout:

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

The deduced polyprotein is of 2,154 amino acids. There is no L protein. 1A is very short (16 amino acids). The function of 2A is unknown.

Biology

No virus has been isolated. Viral RNA was detected in faeces of red-crowned cranes (Grus japonensis).

Derivation of names

Gruhelivirus: derived from Grus japonensis (host) and hepato-like virus
