The phylogenetic analysis shows that SARS-CoV-2 and RmYN02 are the most closely related in most of the genome, although a long branch length still separates the two viruses from each other.

Phylogenetic analysis of RmYN02 and SARS-CoV-2 full-length genome

SARS-CoV-2 and RmYN02 are relatively distant from each other in the spike gene tree, with SARS-CoV-2 being more clustered with RaTG13.

Phylogenetic analysis of RmYN02 and SARS-CoV-2 S gene

In the receptor-binding domain (RBD) phylogeny, SARS-CoV-2 is more closely related to pangolin-CoV/GD than RmYN02.

Phylogenetic analysis of RmYN02 and SARS-CoV-2 receptor-binding domain

A RNA-dependent RNA polymerase (RdRp) phylogeny indicates that RmYN02, RaTG13, and SARS-CoV-2 form a cluster separate from pangolin viruses.
