Book: Fusariviridae
Family: Fusariviridae
Genus: Gammafusarivirus
Distinguishing features
Currently, this genus comprises only one species, but a group of viruses with closely related sequences have been discovered (see “Related, unclassified viruses”) and will likely be classified in this genus: the main distinguishing feature is that the ORF coding for the protein carrying the RdRP motif is larger than those of other fusarivirids, and the virus genomes are, in most cases, monocistronic.
Species demarcation criteria
Viruses belonging to the same species are >80% identical in the full-length sequence of the protein that includes an RdRP domain.
