Microsatellite markers were developed and characterized to investigate genetic diversity and gene flow and to help in conservation efforts for the endangered timber species Plathymenia reticulata. •
Eleven microsatellite loci were characterized using 60 adult trees of two populations of P. reticulata from the Atlantic Forest of southern Bahia, Brazil. Of these, nine loci were polymorphic, with an average of 4.39 alleles per locus. The average expected heterozygosity per population ranged from 0.47 to 0.55. The combined exclusion probability was 0.99996. •
Our results reveal that the microsatellite markers developed in this study are an effective tool for paternity and genetic structure analysis that may be useful for conservation strategies.
开发和表征微卫星标记，以调查遗传多样性和基因流动，并有助于濒危木材物种Plathymenia reticulata 的保护工作。
使用来自巴西巴伊亚南部大西洋森林的两个 Plathymenia reticulata 种群的 60 棵成年树木对 11 个微卫星位点进行了表征。其中，9 个位点多态性，每个位点平均有 4.39 个等位基因。每个种群的平均预期杂合度范围从 0.47 到 0.55。联合排除概率为 0.99996。
我们的研究结果表明，本研究中开发的微卫星标记是一种用于亲子关系和遗传结构分析的有效工具，这对于保护策略可能是有用的。
