赛冷蒿是一种用途广泛的保健食品,也是一种著名的中药材。然而,目前只有一小部分蒿属植物的叶绿体基因组数据被报道,而没有关于艾蒿属植物的报道。在这项研究中,我们提供了一个完整的叶绿体基因组,并分析了它与菊科其他28个近缘物种的亲缘关系。结果表明,该基因组全长151215 ,具有典型的保守四分体结构。全基因组、LSC、SSC和IRA/IRB区总GC含量分别为37.46%、35.55%、30.81%和43.09%。共鉴定出133个基因,其中88个为蛋白质编码基因,37个为转移RNA基因,8个为核糖体RNA基因。其中19个基因含有1个内含子,2个基因含有2个内含子。系统发育关系分析表明,塞伦格氏原虫与格梅里尼原虫相似。本文提供的完整叶绿体基因组将丰富药用植物的遗传资源,促进我们对菊科蒿属系统发育的了解。
Artemisia selengensis 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 Artemisia has been reported and there was no report for A. selengensis. In this study, we presented the complete chloroplast genome of A. selengensis and analysed its phylogenetic relationship with other 28 related species belonging to the Asteraceae 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 A. selengensis was similar to A. gmelinii. The complete chloroplast genome presented here will enrich the genetic resources of medicinal plant and promote our understanding of the phylogeny of Artemisia within the Asteraceae family.
