Complete chloroplast genome sequence of Stephania kwangsiensis (Menispermaceae), a rare and critically endangered species endemic to China

Stephania kwangsiensis (Menispermaceae) is a rare and critically endangered species endemic to China. Here, we first report and characterize its complete chloroplast genome sequence based on Illumina paired-end sequencing data. The complete plastid genome was 156,624bp, which contained inverted repeats (IR) of 24,348bp separated by a large single-copy (LSC) and a small single copy (SSC) of 87,759bp and 20,169bp, respectively. The cpDNA contains 132 genes, comprising 85 protein-coding genes, 37 tRNA genes, eight rRNA genes, and two processed pseudogenes. The overall GC content of the plastome is 38.4%. The phylogenetic analysis of 18 selected chloroplast genomes demonstrated that S. kwangsiensis is related to the congeneric S. japonica.
