Subfamily: Variarterivirinae

Subfamily: Variarterivirinae

Distinguishing features

Members of this subfamily form a clade upon phylogenetic analysis (Figure 3.Arteriviridae). They encode an nsp2 protein that is considerably larger than its counterparts in viruses of other subfamilies, mostly due to the hypervariable region flanked by PLP2 and TM1.  

Genus demarcation criteria
