Elymus kamoji (Ohwi) S. L. Chen is a perennial herb, had high grazing value and were important forage resources, the study of E. kamoji chloroplast genome (cp genome) provides an important basis for the study of chloroplast genetic engineering and system evolution. Its chloroplast genome was 135,075 bp in length, containing a pair of inverted repeated (IR) regions (20,813 bp), separated by a large single copy region (LSC) of 80,681 bp, and a small single copy (SSC) region of 12,768 bp. Moreover, a total of 129 functional genes were annotated, including 83 mRNA, 38 tRNA genes, and 8 rRNA genes. The phylogenetic relationships of 15 species indicated that E. kamoji was closely related to Elymus sibiricus. This study might contribute to provide a theoretical basis for species identification and biological research.
Keywords: Elymus kamoji (Ohwi) S. L. Chen; chloroplast genome; phylogenetic relationship.
