Maximum likelihood phylogenetic tree of RdRp amino acid sequences from picobirnavirus and representatives from other dsRNA virus families. Scale bar corresponds to 0.9 substitutions per amino acid. Putative genogroups I and II are shown in the Picobirnaviridae (gold shaded) portion of the tree. Related families Partitiviridae (green) and Birnaviridae (blue) are also shaded. Branch support values are presented as coloured nodes (black > 0.8, red < 0.8).
