The genus is distinguished on the basis of genetic characters.
No details are available on the morphology of virions.
Genome (S. Yang, Y. Wang, W. Zhang, unpublished): c. 7,073 nt (5′-UTR: 609 nt; ORF: 6,462 nt).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
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.
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
