Characterization of the complete chloroplast genome of Elymus dahuricus

Abstract

Elymus dahuricus, a widely distributed perennial herb on the Qinghai-Tibetan Plateau, is highly adapted to alpine regions. In this study, we first reported the complete chloroplast (cp) genome of E. dahuricus using Illumina sequencing data. The size of the chloroplast genome is 135,096 bp, including a pair of inverted repeat regions (IRs, 20,812 bp), a large single copy region (LSC, 80,701 bp), and a small single single copy region (SSC, 12,771 bp). The chloroplast genome of E. dahuricus contained 111 genes, including 78 protein-coding genes, four ribosomal RNA genes, and 29 transfer RNA genes. Phylogenetic tree analysis suggested that E. dahuricus was closely related to E. libanoticus.
