Abstract

Understanding the genetic diversity in natural plant populations is important in order to develop conservation strategies and utilize valuable germplasm resources. Chrysanthemum arcticum L., Arctic daisy, (=Arctanthemum arcticum; =Dendranthema arcticum) and its two subspecies (C. arcticum L. subsp. arcticum, C. arcticum L. subsp. polaré Hultén) are the only chrysanthemum species native to North America. We collected 529 individuals in nine C. arcticum and 21 C. a. subsp. arcticum populations from the state of Alaska mainland and Attu Island (the westernmost Aleutian Island). Evidence of declining population sizes and decreasing ranges of distribution were detected for both species and subspecies. Population genetic diversity was analyzed using 7,449 SNP markers developed using low density DArTseq technology. Three distinct genetic clusters within C. arcticum populations were detected by STRUCTURE 2.3.4, principal coordinate analysis (PCoA), discriminant analysis of principal components (DAPC), unweighted pair group method with arithmetic mean (UPGMA) and SplitsTree. SNP data showed a clear taxonomic distinction among C. arcticum and C. a. subsp. arcticum. However, within C. a. subsp. arcticum populations, two subgroups occurred in the genetic cluster analyses that were a mixture of individuals from different populations, which may be the result of gene flow.

了解自然植物群体的遗传多样性对制定保护策略和利用宝贵的种质资源具有重要意义。菊花(Chrysanthemum arcticum L.),北极雏菊;北极菊)及其两个亚种(北极菊L. subsp.;arcticum, C. arcticum L. subsp。极乐菊(hultsamn)是唯一一种原产于北美的菊花。共收集到9个冰杉种和21个冰杉亚种529个个体。阿拉斯加大陆和阿图岛(阿留申群岛最西端)的北极冰种群。物种和亚种的种群规模和分布范围均呈下降趋势。利用低密度DArTseq技术开发的7449个SNP标记分析群体遗传多样性。利用STRUCTURE 2.3.4、主坐标分析(PCoA)、主成分判别分析(DAPC)、非加权算术平均对群法(UPGMA)和splitstreet等方法,对木桉居群中3个不同的遗传聚类进行了分析。单核苷酸多态性数据显示,冰孢和亚孢有明显的分类学差异。arcticum。然而,在c.a.b sp。在遗传聚类分析中,北极木居群中出现了两个亚群,它们是来自不同居群的个体的混合,这可能是基因流动的结果。

期刊介绍: Arctic Science is an interdisciplinary journal that publishes original peer-reviewed research from all areas of natural science and applied science & engineering related to northern Polar Regions. The focus on basic and applied science includes the traditional knowledge and observations of the indigenous peoples of the region as well as cutting-edge developments in biological, chemical, physical and engineering science in all northern environments. Reports on interdisciplinary research are encouraged. Special issues and sections dealing with important issues in northern polar science are also considered.
