The chloroplast genome of Elytrigia repens (L.) Nevski (Poaceae: Triticeae), a widespread perennial grass from Qinghai-Tibetan Plateau, China

Abstract

Elytrigia repens (L.) Nevski, belonging to Triticeae of Poaceae, is a wild-growing perennial grass, widely distributed in Qinghai-Tibetan Plateau of China. In this study, the complete chloroplast genome of E. repens was sequenced and analyzed. The complete chloroplast genome size is 134,749 bp with 38.3% GC content. It includes 136 genes, including 89 protein-coding genes, 39 tRNAs genes, and 8 rRNAs genes. Based on chloroplast genome sequences, further phylogenetic analyses between E. repens and other Triticeae species revealed that E. repens, Connorochloa tenuis and three Elymus species formed a distinct clade, showing closer relationships.
