The complete chloroplast genome sequence of Bromus catharticus Vahl. (Poaceae)

Abstract

Bromus catharticus Vahl. belongs to the Pooideae subfamily of Poaceae. In this study, we sequenced and assembled the complete chloroplast genome of B. catharticus. The complete chloroplast genome was 134,718 bp in size, including a large single-copy region of 80,540 bp, a small single-copy region of 11,806 bp and a pair of reverse repeats of 21,186 bp in size. The annotation of B. catharticus indicates that it contained 89 protein-coding genes, 47 tRNA genes and eight rRNA genes. Our phylogenetic analysis of all protein-coding genes of the 36 grass complete chroloplast genomes using Cyperus rotundus as outgroup showed that B. catharticus is closely related to the Koeleria and Avena species to form the Pooideae lineage of the grass family.
