Unrooted ssRNA (+) viruses Capsid and RdRp phylogeny. Unrooted phylogenetic tree of ssRNA (+) (a) RdRps and (b) capsids, aligned by MAFFT and phylogeny performed using PhyML. Shading indicates the viral supergroup to which clusters belong, as indicated by the key. Red arrows demonstrate the disparate genetic relationships for non-structural and structural proteins between supergroups, for viruses belonging Hepeviridae and Astroviridae. The capsid type of each cluster or group is depicted by an icon as indicated in the legend. Scale bars indicate number of nucleotide substitutions per site
