Phylogenetic tree, divergence time of seven species (a), and the four-fold degenerate third-codon transversion rate of gene pairs in three Medicago species (b). The phylogenetic tree was constructed based on 843 single-copy orthologous genes across M. ruthenica and the other six species by RAxML software, and the divergence times (Mya) are indicated by the blue numbers beside the branch nodes in panel a. The common whole-genome duplication events are indicated by the peaks (4DTv=0.32) in panel b
