Polymorphic microsatellite loci were developed in Torreya jackii, an endangered species in China, to provide markers for further studies on the genetic diversity of this species.
Eight polymorphic loci and one monomorphic locus were developed and characterized in four T. jackii populations (Xianju, Songyang, Pujiang, and Tonglu) from Zhejiang Province, China. The number of alleles per locus ranged from one to eight across 80 T. jackii individuals. At the eight polymorphic loci, the observed heterozygosity ranged from 0.150 to 1.000 and the expected heterozygosity ranged from 0.185 to 0.796.
The microsatellite loci developed and characterized in this study will facilitate future analyses of the genetic diversity of T. jackii. Such information will aid in designing strategies to conserve this currently endangered species.
在中国濒危物种 Torreya jackii 中开发出多态微卫星位点，为进一步研究该物种的遗传多样性提供标记。
在中国浙江省的四个 Torreya jackii 种群（仙居、松阳、浦江和桐庐）中开发和表征了 8 个多态性位点和 1 个单态性位点。80 个 Torreya jackii 个体的每个位点的等位基因数从 1 到 8 不等。在 8 个多态性位点中，观察到的杂合度范围为 0.150 至 1.000，预期杂合度范围为 0.185 至 0.796。
本研究中开发和表征的微卫星位点将有助于未来分析 Torreya jackii 的遗传多样性。这些信息将有助于制定保护当前濒危物种的策略。
