Chloroplast (cp) genome sequences become a useful popular tool for population and phylogeny in recent reports. Here, the complete chloroplast genome of the has been reconstructed from the whole-genome Illumina sequencing data. The circular genome is 159,325 bp in size, and comprises a pair of inverted repeat (IR) regions of 67,788 bp each, a large single-copy (LSC) region of 84,593 bp, and a small single-copy (SSC) region of 6,944 bp. The total Guanine and Cytosine (GC) content is 38.0%, while the corresponding values of the LSC, SSC, and IR region are 36.3%, 34.5%, and 40.2%, respectively. The chloroplast genome contains 131 genes, including 94 protein-coding genes, eight ribosomal RNA genes, and 29 transfer RNA genes. The Maximum-Likelihood Phylogenetic analysis showed a strong sister relationship with in Polygonaceae. Our findings provide a foundation for further investigation of cp genome evolution in and other higher plants.
叶绿体（cp）基因组序列在最近的报道中成为用于种群和系统发育研究的一种有用且流行的工具。在此，已从全基因组Illumina测序数据中重建了该物种的完整叶绿体基因组。该环状基因组大小为159,325 bp，由两个各为67,788 bp的反向重复（IR）区域、一个84,593 bp的大单拷贝（LSC）区域和一个6,944 bp的小单拷贝（SSC）区域组成。鸟嘌呤和胞嘧啶（GC）的总含量为38.0%，而LSC、SSC和IR区域的相应值分别为36.3%、34.5%和40.2%。叶绿体基因组包含131个基因，包括94个蛋白质编码基因、8个核糖体RNA基因和29个转运RNA基因。最大似然系统发育分析表明它与蓼科中的某物种有很强的姐妹关系。我们的研究结果为进一步研究该物种及其他高等植物的叶绿体基因组进化提供了基础。
