Figure 1

Maximum clade credibility tree from the Bayesian analysis of plastid DNA sequences (trnH-psbA, trnT-L, trnL-F, ndhF and matk) from 163 samples representing 152 Pooideae, 6 PACMAD, 3 Bambusoideae and 1Oryzoideae grass species and Joinvillea ascendens as outgroup, constructed with BEAST using a Yule prior. Divergence times were inferred using a relaxed molecular clock. Dashed lines represent branches with PPS < 0.8. Mes., Mesozoic; Cr., Cretaceous; Oligo., Oligocene; Pl., Pliocene; Pt., Pleistocene; Qt., Quaternary. Diamond and star symbols indicate the fossil-based calibration priors imposed to the crown nodes of Pooideae and Stipeae, respectively.
