Space and tempo in the evolutionary history of Oryza. a Combined chronogram and biogeographical analyses of Oryza. The MCC tree was generated from the dating analysis of Oryza and other Oryzeae in scenario #1. Grey bars represent 95 % highest posterior density intervals for each node. Node charts show the relative probabilities of alternative ancestral distributions obtained by Statistical Dispersal-Vicariance Analysis (S-DIVA) optimisations over the 1000 Bayesian trees (white > red > blue); areas (frequencies < 0.1) are shown in black. Numbers in red near branches indicate the node number, as noted in Table 1. Genome types are shown at the right. b Lineage-through-time (LTT) plots for Oryza, excluding outgroups. The grey lines represent the results of 1000 trees randomly selected from the BEAST analysis. The black line shows the MCC tree. c Maximum-likelihood diversification rate estimates for Oryza. The solid line represents the best model and the dashed line represents the other models
