Abstract

Bothriochloa ischaemum (Linn.) 1936 is a high-quality perennial forage in Loess Plateau of China. In this study, we sequenced and characterized the complete chloroplast genome of B. ischaemum, which was a circular DNA of 138,316 bp in length, including a large single copy (LSC) region of 80,226 bp, a small single copy (SSC) region of 12,526 bp, and the circular DNA was separated by a pair of identical inverted repeat regions (IRs) of 22,782 bp each. A total of 134 genes were identified, including 87 protein-coding genes, 39 tRNA genes, and eight rRNA genes. Phylogenetic tree showed that B. ischaemum was closer to B. decipiens and B. alta, genus Bothriochloa was closely related to genus Pseudanthistiria. Our findings will be helpful for better understanding of genetic diversity of Bothriochloa plants.

Keywords: Bothriochloa ischaemum; chloroplast genome; phylogenetic analysis.
