The complete chloroplast genome sequence of traditional Tibetan herb, Maxim. was analyzed. The complete chloroplast genome of is 162,213 bp in size and has a 27.27% GC content. In the typical circular quadripartite structure, there was a pair of inverted repeat (IR) regions with 31,023 bp in length, which separated by a large single-copy (LSC) region (87,424 bp) and a small single-copy (SSC) region (12,743 bp). The chloroplast genome of contained 131 unigenes, which was composed of 86 protein-coding genes, 37 tRNA and 8 rRNA genes. Moreover, 238 SSRs were identified and 58.8% of them existed in LSC region. A maximum likelihood (ML) phylogenetic analysis based on chloroplast genomes indicated that was closely related to , , and . Our results would provide a valuable resource for resource utilization and the phylogenetic studies of Rheum in Polygonaceae.
对传统藏药大黄（Maxim.）的完整叶绿体基因组序列进行了分析。大黄的完整叶绿体基因组大小为162,213 bp，GC含量为27.27%。在典型的环状四分体结构中，有一对长度为31,023 bp的反向重复（IR）区域，它们被一个大单拷贝（LSC）区域（87,424 bp）和一个小单拷贝（SSC）区域（12,743 bp）隔开。大黄的叶绿体基因组包含131个单基因，由86个蛋白质编码基因、37个tRNA和8个rRNA基因组成。此外，鉴定出238个简单序列重复（SSR），其中58.8%存在于LSC区域。基于叶绿体基因组的最大似然（ML）系统发育分析表明，大黄与掌叶大黄、唐古特大黄和药用大黄密切相关。我们的结果将为蓼科大黄属的资源利用和系统发育研究提供有价值的资源。
