, a critically endangered species endemic to North China with about 30 wild individuals, has long been ignored for conservation since its publication because of little attention on its living situation. In this study, we characterized the complete chloroplast (cp) genome of . The cp genome was 155,481 bp in length, included a large single-copy (LSC) region of 89,139 bp, a small single-copy (SSC) region of 18,676 bp, and two inverted repeat (IR) regions of 23,833 bp each. The genome contains 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic position of was also investigated based on cp genome phylogeny of representatives. This study is valuable for molecular phylogenetic study and conservation of and related taxa.
是一种极度濒危的物种，特产于中国北方，野生个体约有30只。自其被发现以来，由于对其生存状况关注甚少，长期以来一直被忽视用于保护。在本研究中，我们对的完整叶绿体（cp）基因组进行了特征分析。该cp基因组长度为155,481 bp，包括一个89,139 bp的大单拷贝（LSC）区域、一个18,676 bp的小单拷贝（SSC）区域以及两个各为23,833 bp的反向重复（IR）区域。该基因组包含130个基因，包括85个蛋白质编码基因、37个tRNA基因和8个rRNA基因。还基于代表物种的cp基因组系统发育研究了的系统发育位置。本研究对于的分子系统发育研究和保护以及相关类群具有重要价值。
