Abstract

Saussurea dorogostaiskii Palib. (Asteraceae) is a critically endangered medicinal plant in Mongolia and Russia. We studied the genetic variation of S. dorogostaiskii from three mountains of northern Mongolia. The genetic profile was assessed in 70 individuals from eight populations using five inter-simple sequence repeat markers, producing 53 loci with 96.4% polymorphism across all bands. Shannon’s index (I) and Nei’s gene diversity (H) value at the species level of S. dorogostaiskii are 0.25 and 0.17, respectively. An AMOVA showed high genetic variation among the populations (22% of populations and 32% of mountains), consistent with the high genetic differentiation (GST = 0.49) and low gene flow (Nm = 0.51) in S. dorogostaiskii populations. Eight populations were clustered into two groups, corresponding to their geographic locations. The low within-population genetic diversity and high genetic differentiation among S. dorogostaiskii populations factor into their endangered designation. This genetic analysis reveals that all populations are equally threatened, and community-based conservation is appropriate for these species.

蒙古Khuvsgul地区受威胁的多萝西雪莲(Asteraceae)的遗传多样性
多罗戈斯泰斯基雪莲。(菊科)是蒙古和俄罗斯的一种极度濒危的药用植物。我们研究了蒙古国北部三山地区多罗戈斯泰斯基猪笼草的遗传变异。使用五个简单序列间重复标记对来自八个群体的70个个体的遗传图谱进行了评估,产生了53个位点,所有谱带的多态性为96.4%。dorogostaiskii的Shannon指数(I)和Nei基因多样性(H)在物种水平上分别为0.25和0.17。AMOVA显示出种群之间的高遗传变异(22%的种群和32%的山地),与S.dorogostaiskii种群的高遗传分化(GST=0.49)和低基因流(Nm=0.51)一致。八个种群按照其地理位置分为两组。dorogostaiskii种群内部遗传多样性低,遗传分化程度高是其濒危物种的因素。这一基因分析表明,所有种群都受到同样的威胁,基于社区的保护对这些物种来说是合适的。
