The subspecies subsp exhibits pharmacological properties akin to the traditional Chinese medicinal plant ( subsp (Hance) Verdc.). In this report, we unveil the plastid genome of subsp. The genome spans 156,322 base pairs (bp), comprising a large single-copy (LSC) region of 86,633 bp, a small single-copy (SSC) region of 18,219 bp, and two distinct inverted repeat regions (IRs) of 25,735 bp each. Annotation process cataloged a total of 111 genes within this genome, including 77 protein-coding genes, 30 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. The overall guanine-cytosine (GC) content of the plastome is 35.5%. Phylogenetic analysis utilizing maximum-likelihood (ML) based on 16 complete plastid genomes reveals a close clustering of three taxa, namely subsp, subsp, and . Notably, subsp clusters with as a sister group, distinct from subsp. These findings highlight significant differences between the plastid genomes of the two subspecies, laying the foundation for future research on the identification of medicinal herbs and germplasm resources related to these subspecies.
亚种subsp表现出与传统中药材（subsp (Hance) Verdc.）相似的药理特性。在本报告中，我们公布了subsp的质体基因组。该基因组跨度为156,322个碱基对（bp），包括一个86,633 bp的大单拷贝（LSC）区域、一个18,219 bp的小单拷贝（SSC）区域以及两个各为25,735 bp的不同反向重复区域（IRs）。注释过程在该基因组中共编目了111个基因，包括77个蛋白质编码基因、30个转运RNA（tRNA）基因和4个核糖体RNA（rRNA）基因。质体基因组的总体鸟嘌呤-胞嘧啶（GC）含量为35.5%。基于16个完整质体基因组的最大似然法（ML）系统发育分析显示，三个类群，即subsp、subsp和，紧密聚类。值得注意的是subsp与作为姐妹群聚类，与subsp不同。这些发现突出了两个亚种质体基因组之间的显著差异，为今后与这些亚种相关的药用植物鉴定和种质资源研究奠定了基础。
