Table 1.
Posterior probabilities, mean, and median time to the most recent common ancestor (million years), 95% HPD interval, and the effective sample size inferred for clades A–F in Fig. 2 from the trnfMCAU-trnSUGA and trnSGCU-trnGUUC plastid regions (Fig. S2) and the nuclear RPC2 and RPB2-I regions (Figs. S3 and S4), respectively
