The complete chloroplast genome of Aristolochia hainanensis Merr. (Aristolochiaceae)

Aristolochia hainanensis Merr. 1922, a well-known Chinese medicinal plant, is distributed in Hainan Province and Guangxi Province, China. In the current study, we sequenced the complete chloroplast genome of A. hainanensis. The complete plastome genome was 159,764 bp in length, with a GC content of 38.8%, showing a typical quadripartite organization. The genome contained a large single-copy (LSC) of 89,134 bp, a small single-copy (SSC) of 19,306 bp, and a pair of inverted repeats (IRs) of 25,662 bp. A total of 113 genes were annotated, including 79 protein-coding genes, 30 tRNAs, and four rRNAs. The trnK-UUU gene contained the longest intron (2644 bp). The topology of the maximum-likelihood tree supported a close relationship between A. hainanensis and A. kwangsiensis.
