Global phylogeny of avian gammacoronavirus partial RdRp.
(a) Radial projection of all current wild bird sequences, including only a few “IBV-like” sequences to root the tree, and (b) the clade containing most of the Mallard CoV sequences generated in this study. Tips are coloured by geographic origin of sequence, Mallard CoV sequences generated in this study are indicated with a filled circle and Scaup CoV sequences with an asterisk. Scale bar represents number of substitutions per site. Traditional projection of panel A with support values is presented in S2 Fig.
