is a perennial herb used in traditional Chinese medicine and is effective against rheumatoid arthritis. In this study, we sequenced the complete mitochondrial (mt) genome of (GenBank accession number: ON584565.1). The circular mt genome of was 335,372 bp in length, containing 62 genes, including 33 mRNAs, 22 tRNAs, 6 rRNAs, and 1 pseudogene, along with 1626 open reading frames. The GC content was 45.14%. Predictive analysis revealed substantial RNA editing, with being the most abundantly edited gene, showing 36 sites. Gene migration between the mt and chloroplast (cp) genomes of was observed through the detection of homologous gene fragments. Phylogenetic analysis revealed that was clustered with (Asteraceae). Our findings provide extensive information regarding the mt genome of and help lay the foundation for future studies on its genetic variations, phylogeny, and breeding via the analysis of the mt genome.
是一种多年生草本植物，用于中药，对类风湿性关节炎有效。在这项研究中，我们对 （GenBank 登录号：ON584565.1）的完整线粒体（mt）基因组进行了测序。 的圆形 mt 基因组长 335372bp，包含 62 个基因，包括 33 个 mRNAs、22 个 tRNAs、6 个 rRNAs 和 1 个假基因，以及 1626 个开放阅读框。GC 含量为 45.14%。预测分析显示存在大量 RNA 编辑，其中 编辑最多，有 36 个位点。通过同源基因片段的检测，观察到 mt 和叶绿体（cp）基因组之间的基因迁移。系统发育分析表明 与 （菊科）聚类在一起。我们的研究结果为 的 mt 基因组提供了广泛的信息，并有助于通过 mt 基因组分析为其遗传变异、系统发育和繁殖的未来研究奠定基础。
