belonging to family Rosaceae, is an indigenous species distributed in Tibet, China. assembly with low coverage whole genome sequencing data facilitated to generate the complete chloroplast (cp) genome of in this study. The genome was a circular DNA molecule with 158,153 bp in length. It exhibited a typical quadripartite structure comprising a large single-copy region (LSC, 86,319 bp), a small single-copy region (SSC, 19,022 bp) and a pair of inverted repeat regions (IRs, 26,406 bp each). A total of 112 genes were predicted, which included 78 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. Phylogenetic analysis indicated that was the most ancestral and basal lineage within the subgenus (Prunoideae subfamily), which is conform to the traditional classification.
属于蔷薇科，是一种分布于中国西藏的本土物种。在本研究中，利用低覆盖度全基因组测序数据组装，成功获得了该物种完整的叶绿体（cp）基因组。该基因组是一个长度为158,153 bp的环状DNA分子。它呈现出典型的四分体结构，包括一个大单拷贝区域（LSC，86,319 bp）、一个小单拷贝区域（SSC，19,022 bp）和一对反向重复区域（IRs，各26,406 bp）。共预测出112个基因，其中包括78个蛋白质编码基因、30个tRNA基因和4个rRNA基因。系统发育分析表明，该物种是李亚属（李亚科亚族）中最原始和基部的谱系，这与传统分类相符。
