Fig. 2: Genome expansion and phylogenetic analyses for the Chinese tallow tree (CTT).

a Orthogroups in the 12 plants, namely, CTT, Arabidopsis thaliana, Eucalyptus grandis, Hevea brasiliensis, Jatropha curcas, Linum usitatissimum, Manihot esculenta, Oryza sativa, Populus trichocarpa, Ricinus communis, Salix purpurea, and Vitis vinifera. b Functional enrichment of specific genes in the CTT genome. FDR represents the false discovery rate. c Phylogenetic tree for 12 plants listed in a. Single-copy genes were used to construct this tree with the PROTGAMMAAUTO model in RAxML. “+” and “−” indicates gene expansion and contraction, respectively. The green and blue numbers indicate numbers of othogroups that expand or contract, respectively. The red numbers indicate divergent time. For example, 89.0 [70.4–98.9] indicates the average divergent time is 89.0 million years ago (MYA), and its 95% confidence interval is 70.4 to 98.9 MYA. Plants with yellow backgrounds belong to Euphorbiaceae family. d Functional enrichment of significantly expanded genes in the CTT genome.
