Figure 9

Divergence times of Vitaceae and Tetrastigma species estimated based on the shared CDS sequences of the chloroplast genome, with Leea guineensis from the Leeaceae as the outgroup. The mean divergence times are shown next to the nodes, and the red bars correspond to the Clade Age height 95% HPD. (A–D) represent clade nodes used for priors, where the values indicate the results of estimated divergence times in this analysis, not priors. Specifically, (A) represents the deep calibration point for Leea and Vitaceae; (B) the existing fossil record of Tetrastigma; (C) for the genus Ampelopsis; (D) for the subgenus Vitis. (a–c) indicate the estimated divergence times within Tetrastigma, corresponding to the results in 2.6. The bottom of the figure shows the Geologic Time Scale, with the Lower Epoch of the Cretaceous Period (145–100.5 Mya) and the Holocene Epoch of the Quaternary Period (0.0117 Mya–present) omitted.
