Characterization of the complete chloroplast genome of the medicinal shrub Caragana brevifolia Kom. (Fabales: Fabaceae)

Caragana brevifolia Kom. is a species of shrub with high medicinal value, and is mainly distributed in China, India and Pakistan. In this study, the chloroplast genome of C. brevifolia was determined to be 132,359 bp long with an asymmetric nucleotide composition (32.7%A, 16.7%C, 18.0%G and 32.6%T). It encodes a panel of 110 genes (incl. 76 protein-coding, 30 tRNA and four rRNA genes) with one of them being duplicated and 17 of them containing intron(s). Phylogenetic analysis suggested that C. brevifolia was most closely related to the congeners Caragana rosea Turcz. ex Maxim. and Caragana stenophylla Pojark.
