Here, we present the first complete chloroplast genome of (154,018 bp), which exhibits a typical quadripartite structure, including an LSC (83,966 bp), SSC (18,910 bp), and two IRs (25,571 bp each). A total of 133 genes were annotated, with 114 unique genes and 19 duplicated in the IRs. .Phylogenetic analyses based on complete chloroplast genomes of 13 species strongly supported as sister to (BS = 100%, PP = 1.0), challenging earlier studies that suggested a sister relationship with based on partial plastid sequences. Overall, this study provides a critical genomic resource for advancing research on the taxonomy, evolution, and medicinal breeding of .
在此，我们展示了（154,018 bp）的首个完整叶绿体基因组，其呈现出典型的四分体结构，包括一个大单拷贝区（LSC，83,966 bp）、一个小单拷贝区（SSC，18,910 bp）以及两个反向重复区（IRs，各25,571 bp）。总共注释了133个基因，其中有114个独特基因以及19个在反向重复区中重复。基于13个物种的完整叶绿体基因组进行的系统发育分析有力地支持了[具体物种]与[另一具体物种]为姐妹关系（自展支持率 = 100%，后验概率 = 1.0），这对早期基于部分质体序列表明[具体物种]与[另一具体物种]为姐妹关系的研究提出了挑战。总体而言，本研究为推进[具体物种]的分类学、进化及药用育种研究提供了关键的基因组资源。
