a Molecular phylogenetic tree of 20 representative angiosperm species constructed using 2133 concatenated conserved protein sequences by the ML and BI methods. b Phylogenetic tree of A. sinensis and other Apiaceae species, inferred by estimating divergence time using 3188 single-copy ortholog sequences. P. notoginseng was used as an outgroup. The numbers in green and red colors indicate gene family expansion and contraction compared with the most recent common ancestors, respectively. Estimated divergence times (MYA, million years ago) are indicated at each node. The Venn diagram shows the proportion of gene families under the unchanged (blue), expansion (red) and contraction (green) scenarios. c KEGG pathway enrichment analysis of expanded gene families in the A. sinensis (QH) genome. Only the enriched KEGG pathways with p values < 0.05 are displayed. d Distribution of 4DTv distances of syntenic orthologous genes of Apiaceae species. The black arrows mark the WGD events. e The KS distribution for orthologous gene pairs within Apiaceae species. V. vinifera was used as the model organism for evolutionary analysis. The shape of the curve and the position of the peak are almost identical between A. sinensis (QH) and A. sinensis (GS). The highlighted peak regions represent two WGD events.
