FIG 5.

HVR structural evolution among select Alpha- and Betacoronaviruses. Maximum likelihood (Minh et al. [272]) phylogenies were reconstructed for the HVR region (left) and near-full-length genomes (right), with bootstrapping (10,000 replicates) used to provide support (BS). BS ≥90% are indicated by black circles. Within each predicted RNA structure, the ONM and S2M motifs have been highlighted in purple and teal, respectively, if present. Branch lengths are scaled in substitutions/site (scale at bottom left).
