Molecular phylogeny revealed complex evolutionary process in Elymus species

Recent molecular phylogenetic studies on Elymus have added to our understanding of the origination of Elymus species. However, evolutionary dynamics and speciation of most species in Elymus are unclear. Molecular phylogeny has demonstrated that reticulate evolution has occurred extensively in the genus, as an example, the largest subunit of RNA polymerase II (rpb2) and phosphoenolpyruvate ca…
