Abstract

Analysis of chloroplast DNA sequences revealed a high polymorphism of the length and nucleotide composition of trnF–trnV and the intron trnL for Helmia section species of the genus Astragalus (Fabaceae). Molecular genetic studies of Astragalus species of the Helmia section were previously practically not carried out; sequencing of trnF–trnV and the intron trnL of chloroplast DNA for 7 species of the section, as well as the probable intersection hybrid Astragalus arcanus held for the first time. On the basis of genetic studies, clarified the relationship between species included in the section Helmia. The possible stages of sect. Helmia evolution are discussed. The taxonomic isolation of Astragalus permiensis has been confirmed; it is assumed not to be of Uralic, but of Siberian or Central Asian origin. Astragalus ionae belongs to the section Helmia is confirmed. Astragalus depauperatus s. l. is thought to be a complex of twin species. In this article, one of them is considered in the status of the species A. chakassiensis. Copy Translate

对一些黄芪科植物叶绿体 DNA 变异性的研究Helmia and A. arcanus of sect.Erioceras（豆科）

对叶绿体 DNA 序列的分析表明，黄芪属（豆科）禾本科黄芪种的 trnF-trnV 和内含子 trnL 的长度和核苷酸组成具有高度多态性。以前几乎没有对黄芪科的黄芪物种进行过分子遗传学研究；首次对该科 7 个物种以及可能的交叉杂交种黄芪 arcanus 的叶绿体 DNA trnF-trnV 和内含子 trnL 进行了测序。在遗传研究的基础上，澄清了 Helmia 节中物种之间的关系。讨论了 Helmia 科进化的可能阶段。讨论了 Helmia 进化的可能阶段。确认了 permiensis 黄芪在分类学上的孤立性；认为它不是乌拉尔黄芪，而是西伯利亚黄芪或中亚黄芪。黄芪离子属（Astragalus ionae）属于禾本科（Helmia）的观点得到了证实。黄芪（Astragalus depauperatus s. l.）被认为是孪生种的复合体。在本文中，其中一个物种被认为是 A. chakassiensis。复制翻译
