Comparative genomic analysis of M. paniculata. A Phylogenetic tree constructed using coding sequences of single-copy gene families among 9 Aurantioideae species. Divergence times were estimated by MCMCTree. Support rates were calculated by RAxML-NG with GTR + G model and 200 bootstraps. All nodes have a bootstraps support percentage of 100. The green and red numbers on the tree or next to the species label indicate the expansion and contraction gene family counts. B Density distributions of collinear block Ks (synonymous substitutions per synonymous site) median of M. paniculata
