Fig. 3: Phylogenetic relationships among bat-origin RdRp sequences within the Sarbecovirus subgenus (β-CoVs).
From: Origin and cross-species transmission of bat coronaviruses in China
Maximum clade credibility tree (A) including 197 RdRp sequences from the Sarbecovirus subgenus isolated in bats, two sequences of SARS-CoV-2, and one sequence of SARS-CoV isolated in humans and eight sequences isolated in Malayan pangolins (Manis javanica). Well-supported nodes (posterior probability > 0.95) are indicated with a black dot. Tip colors correspond to the host genus; SARS-CoV-2 sequences and SARS-CoV sequence are highlighted in gray and black, respectively. Median-joining network (B) including 197 RdRp sequences from the Sarbecovirus lineage isolated in bats, two sequences of SARS-CoV-2, and one sequence of SARS-CoV isolated in humans and eight sequences isolated in Malayan pangolins (Manis javanica). Colored circles correspond to distinct CoV sequences, and circle size is proportional to the number of identical sequences in the dataset. Small black circles represent median vectors (ancestral or unsampled intermediate sequences). Branch length is proportional to the number of mutational steps between haplotypes.
