Genome evolution and gene family analysis. a A phylogenetic tree was constructed based on 658 high-quality single-copy orthogroups from 10 plant species. Regions T and D represent the time of WGT and WGD in the species, respectively. The numbers of gene-family expansion and contraction on each branch are indicated by red and blue numbers, respectively. b Statistics of orthogroups on each node. Red represents all orthogroups. Blue represents orthogroups with > 50% support. c Statistics of duplicated genes on each node. Red represents all duplicated genes. Blue represents duplicated genes with > 50% support rate. d–f Wordcloud plot of KEGG enrichment analysis of the union of expanded gene families and duplicated genes at Nodes 1, 3, and 8, respectively. Word size represents gene number in a pathway
