var. is an endangered species with high ornamental value in Xinjiang province (China). In this study, we reported a complete chloroplast genome of var. , which was assembled using the next-generation sequencing data. The complete chloroplast genome is 152,816 in length, including a large single copy region of 82,265 bp and a small single copy region of 17,541 bp and two inverted repeat regions of 26,505 bp. A total of 110 functional genes were encoded, consisting of 76 protein-coding genes, 30 transfer RNA genes, and four ribosomal RNA genes. The overall AT content of the chloroplast genome is 63.00%. In addition, 68 SSRs and 31 large repeat sequences were found. In the maximum likelihood tree, a strong phylogenetic signal showed that var. is a species of .
变种是中国新疆一种具有高观赏价值的濒危物种。在本研究中，我们报道了变种的一个完整叶绿体基因组，其是利用二代测序数据组装而成。完整的叶绿体基因组长度为152,816，包括一个82,265 bp的大单拷贝区域、一个17,541 bp的小单拷贝区域和两个26,505 bp的反向重复区域。总共编码了110个功能基因，由76个蛋白质编码基因、30个转运RNA基因和4个核糖体RNA基因组成。叶绿体基因组的总体AT含量为63.00%。此外，还发现了68个简单序列重复（SSRs）和31个大的重复序列。在最大似然树中，一个强烈的系统发育信号表明变种是某一物种的一个种。
