Lagerstroemia L. (Lythraceae) is a widely distributed genus of trees and shrubs native to tropical subtropical environments from Southeast Asia Australia, with numerous species highly valued as ornamentals. Although the plastomes many in this have been sequenced, rates functional gene evolution their effect on phylogenetic analyses not thoroughly examined. We compared three plastome sequence matrices elucidate how differences these datasets affected analyses. Robust relationships for were reconstructed based different partitions multiple methods. Identification single-nucleotide variants within genes also provides basic data patterns may provide insights into those mutations affect protein structure potentially drive divergence via cytonuclear incompatibility. These results well non-synonymous synonymous mutations, indicate that heterotachic modes are present should be accounted molecular evolution. In addition, events dated first time. Several estimates corresponded well-known Earth history events, such reduction global temperatures at Eocene/Oligocene boundary. Our conducted here dissects various useful guide help plant breeders, necessity using plastomic possible combine evidence morphological characteristics investigate complicated interspecies relationship evolutionary dynamics species.
