Phylogenetic relationships of the spike (A), envelope (B), membrane (C), and nucleocapsid (D) protein genes of novel CoVs isolated from wild animals in China. Trees were generated by the neighbor-joining method in the PAUP* program. Values above and below branches are neighbor-joining bootstrap values from 1,000 replicates and Bayesian posterior probabilities, respectively. Analyses were based on 2,802, 339, 831, and 1,692 nucleotides of the spike, envelope, membrane, and nucleocapsid protein genes, respectively. The trees were midpoint rooted. Scale bar, 0.1 nucleotide substitution per site. Red text indicates viruses characterized in this study. For definitions of abbreviations, see the legend to Fig. 1.
