Turcz (Louhao in Chinese) is a widely used health food and a well-known traditional Chinese medicine. However, only a small part of the chloroplast genome data of has been reported and there was no report for . In this study, we presented the complete chloroplast genome of and analysed its phylogenetic relationship with other 28 related species belonging to the family. The result showed that the whole genome was 151 215 bp in length with a typical conserved quadripartite structure. The total GC content of whole genome, LSC, SSC, and IRa/IRb regions was 37.46, 35.55, 30.81, and 43.09%, respectively. A total of 133 genes were identified, including 88 protein-coding, 37 transfer RNA, and eight ribosome RNA genes. Among these genes, nineteen genes contained a single intron and two genes contained two introns. The phylogenetic relationship showed that was similar to . The complete chloroplast genome presented here will enrich the genetic resources of medicinal plant and promote our understanding of the phylogeny of within the Asteraceae family.
款冬（中文名为款冬）是一种广泛使用的保健食品和著名的传统中药。然而，其叶绿体基因组数据仅报道了一小部分，且尚无关于[具体名称缺失]的报道。在本研究中，我们展示了[具体名称缺失]的完整叶绿体基因组，并分析了其与菊科其他28个相关物种的系统发育关系。结果表明，整个基因组长度为151215 bp，具有典型的保守四分体结构。全基因组、LSC、SSC和IRa/IRb区域的总GC含量分别为37.46%、35.55%、30.81%和43.09%。共鉴定出133个基因，包括88个蛋白质编码基因、37个转运RNA基因和8个核糖体RNA基因。在这些基因中，19个基因含有一个内含子，2个基因含有两个内含子。系统发育关系表明[具体名称缺失]与[具体名称缺失]相似。此处展示的完整叶绿体基因组将丰富药用植物的遗传资源，并促进我们对菊科中[具体名称缺失]系统发育的理解。
