Fig. 2: Phylogenetic diversity of the coronaviruses identified here.

a Phylogeny of the Coronaviridae based on amino acid sequences of the RdRp gene. Viruses identified in this study are color-coded according to the animal from which they were sampled. The scale bar depicts the number of amino acid substitutions per site. The tree was rooted with δ-CoVs. b Comparison of the genomic organization and similarity plot of Pika-CoV and related viruses. Predicted ORFs are indicated. Parameters for the similarity plots are: window, 500 bp; step, 100 bp.
