Sedum alfredii is a Zn/Cd hyperaccumulator distributed in East Asia. A total of eight polymorphic microsatellite markers were developed. These loci were screened in 25 individuals from one heavy metal-tolerant population and one nontolerant population, respectively. The average allele number of these markers was 5.25 per locus, ranging from two to nine. Population-specific alleles were found at each locus. The observed and expected heterozygosities ranged from 0.000 to 0.640 and from 0.451 to 0.819. Significant deviation from Hardy-Weinberg equilibrium was detected at both the species and the population level. No significant linkage disequilibrium was detected at population level.
阿尔泰景天是一种分布在东亚的 Zn/Cd 超积累植物。本研究共开发了 8 个微卫星标记，分别对来自一个耐重金属种群和一个非耐重金属种群的 25 个个体进行了筛选。这些标记的平均等位基因数为每个位点 5.25，范围为 2 到 9。每个位点都发现了种群特异性等位基因。观察到的和预期的杂合度范围分别为 0.000 到 0.640 和 0.451 到 0.819。在物种和种群水平都检测到了与 Hardy-Weinberg 平衡的显著偏离。在种群水平没有检测到显著的连锁不平衡。
