is a slow-growing, long-lived deciduous species that belongs to section of genus . In this study, we assembled the complete chloroplast genome of . , and analyzed its phylogenetic relationship. The circular genome was 160,765 bp in length, comprising a large single-copy region (89,975 bp), a small single-copy region (18,788 bp), and a pair of inverted repeat regions (26,001 bp each). The chloroplast genome was predicted to contain 131 genes, including 83 protein-coding genes, 40 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. Overall, the GC content of the chloroplast genome was 36.16%. Phylogenetic analysis suggested that . was closely related to , a representative of section within the genus .
是一种生长缓慢、寿命长的落叶物种，属于属的 组。在本研究中，我们组装了 的完整叶绿体基因组，并分析了其系统发育关系。环状基因组长度为160,765 bp，包括一个大单拷贝区域（89,975 bp）、一个小单拷贝区域（18,788 bp）和一对反向重复区域（各26,001 bp）。叶绿体基因组预计包含131个基因，包括83个蛋白质编码基因、40个转运RNA（tRNA）基因和8个核糖体RNA（rRNA）基因。总体而言，叶绿体基因组的GC含量为36.16%。系统发育分析表明， 与属内 组的代表 密切相关。
