【 摘 要 】

Bromus Inermis Leyss 1761 is a perennial herb with large yield and famous for its high nutritional value and long utilization season. The study of B. inermis chloroplast (cp) genome provides an important basis for the study of chloroplast genetic engineering and system evolution. Its cp genome was 137,153 bp in length, containing a pair of inverted repeated (IR) regions (21,699 bp), separated by a large single copy region (LSC) of 81,137 bp, and a small single copy (SSC) region of 12,618 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 B. inermis was closely related to Bromus biebersteinii. This study might contribute to provide a theoretical basis for species identification and biological research.
