Genus

Genus: Birfecvirus

Family: Lispiviridae

Genus: Birfecvirus

 

Distinguishing features

Members of the genus Birfecvirus are distinguished from members of other genera by their branching on phylogenetic tree constructed with the L-INS-i algorithm and inferred using ModelTest-NG and the LG substitution model, and by having a coding-complete RdRP amino acid sequence that is less than 50% identical to that of members of other genera in the family.
