The complete chloroplast genome of Indigofera stachyodes (Fabaceae), a traditional Chinese medicinal plant.

ABSTRACT: Indigofera stachyodes Lindl. is a traditional medicinal plant in southwestern China. In this study, we report the complete chloroplast genome sequence of I. stachyodes, using next-generation sequencing technology. The complete chloroplast genome of I. stachyodes was 158,039 bp in length with an overall GC content 35.80%, containing a large single-copy (LSC) region of 88,772 bp, a small single-copy (SSC) region of 18,733 bp, and a pair of inverted repeats (IRs) regions of 25,267 bp. In total, there are 128 genes (83 protein-coding genes (PCGs), eight ribosomal RNA (rRNA) genes, and 37 tRNA genes) in the whole chloroplast genome, including 113 unique genes (78 unique PCGs, 31 unique tRNAs, and four unique rRNAs). The phylogenetic analysis indicated that I. stachyodes formed a monophyletic clade with I. tinctoria and I. linifolia, showing that they have close relationship. The complete chloroplast genome of I. stachyodes provides valuable genomic information for the phylogeny, molecular identification and sustainable utilization of this species.
