Abstract

Corethrodendron multijugum (Maxim.) (Fabaceae: Corethrodendron), also known as Hedysarum multijugum, is an important medicinal plant and is widely used in traditional Chinese medicine. To better understand the diversity and phylogeny of C. multijugum and other Fabaceae species, we sequenced and annotated the complete chloroplast genome of C. multijugum using the Illumina HiSeq 2500 platform. This complete genome was 122,994 bp long, and encodes a total of 110 genes, including 76 protein-coding genes (PCGs), 30 transfer RNA genes (tRNAs), and four ribosomal RNA unit genes (rRNAs). The C. multijugum plastid with a G + C content of 34.5% presents a negative AT -skew (-0.002) and a positive GC -skew (0.032). Phylogenetic analysis revealed that C. multijugum is more closely related to Hedysarum petrovii. This study provides genetic resource information for the further study of Corethrodendron.

Keywords: Corethrodendron multijugum; complete chloroplast genome; phylogenetic analysis.
