α-CoV (a) and β-CoV (b) maximum clade credibility annotated trees using complete datasets of RdRp sequences and bat host family as discrete character state. Pie charts located at the root and close to the deepest nodes show the state posterior probabilities for each bat family. Branch colors correspond to the inferred ancestral family with the highest probability. Branch lengths are scaled according to relative time units (clock rate = 1.0). Well-supported nodes (posterior probability > 0.95) are indicated with a black dot. The ICTV approved CoV subgenera were highlighted: Rhinacovirus (L1), Decacovirus (L2), Myotacovirus (L3), Pedacovirus (L5), Nyctacovirus (L6), Minunacovirus (L7), and an unidentified lineage (L4) for α-CoVs; and Merbecovirus (Lineage C), Nobecovirus (lineage D), Hibecovirus (lineage E), and Sarbecovirus (Lineage B) for β-CoVs.
