The first complete chloroplast genome of , a poisonous shrub with important medicinal value, is reported in this study. The plastome is a quadripartite circular shape with 173,042 bp in length. It consists of a large single-copy (LSC) region of 86,330 bp and a small single-copy (SSC) region of 2868 bp, separated by two inverted repeat (IR) regions of 41,922 bp each. The chloroplast genome contains 137 genes, including 91 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The GC content values in the whole cp genome, LSC region, SSC region, and IR region are 36.6%, 34.6%, 28.3%, and 38.9%, respectively. The corresponding numbers of mono-, di-, tri-, tetra- and penta-nucleotides SSRs were 73, 13, 9, 13, and 1. Phylogenetic study revealed that and formed a monophyletic branch and having a close relationship with .
本研究报道了一种具有重要药用价值的有毒灌木的首个完整叶绿体基因组。该质体基因组呈四分体环状，长度为173,042 bp。它由一个86,330 bp的大单拷贝（LSC）区域和一个2,868 bp的小单拷贝（SSC）区域组成，这两个区域被两个各为41,922 bp的反向重复（IR）区域隔开。叶绿体基因组包含137个基因，其中包括91个蛋白质编码基因、38个tRNA基因和8个rRNA基因。整个叶绿体基因组、LSC区域、SSC区域和IR区域的GC含量值分别为36.6%、34.6%、28.3%和38.9%。单核苷酸、二核苷酸、三核苷酸、四核苷酸和五核苷酸SSRs的相应数量分别为73、13、9、13和1。系统发育研究表明，[物种名称1]和[物种名称2]形成一个单系分支，并且与[物种名称3]关系密切。
