We isolated and characterized microsatellite markers in Polygonum cespitosum Blume, an herbaceous annual plant species introduced into North America from Asia that has recently become invasive.
A total of 12 polymorphic and 3 monomorphic loci were screened in 1-2 individuals from each of 20 populations from the introduced and native range, for a total of 24 samples. The number of alleles per locus in the polymorphic loci ranged from 3 to 9, and expected heterozygosity ranged from 0.156 to 0.838.
These new loci will provide tools for examining genetic relatedness among introduced and native populations of this and other related species.
本研究从亚洲引入北美的一年生草本植物多穗蓼（Polygonum cespitosum Blume），最近已成为入侵物种，我们对其进行了分离和微卫星标记的特征描述。
在引入和本地范围内的 20 个种群中，每个种群随机选取 1-2 个个体进行筛选，共获得 24 个样本。多态性位点的每个位点的等位基因数从 3 到 9 不等，预期杂合度从 0.156 到 0.838 不等。
这些新的标记位点将为研究该物种和其他相关物种的引入种群和本地种群之间的遗传关系提供工具。
