Maximum clade credibility (MCC) tree of HCoV-OC43 genotypes. Estimation of the time of the most recent common ancestors (tMRCA) with 95 % highest posterior density (95 % HPD) of HCoV-OC43 genotypes based on the spike gene (S1 domain) (848 bp). Data were analyzed under relaxed molecular clock with GTR + I substitution model and a constant size coalescent model implemented in BEAST. The Malaysian HCoV-OC43 isolates obtained in this study were color-coded and the HCoV-OC43 genotypes (a) to (e) as well as novel lineages 1 and 2 were indicated. The MCC posterior probability values were indicated on the nodes of each genotype
