摘要: 为了提高三角帆蚌微卫星分析效率, 从已开发的微卫星标记中构建了三组四重PCR, 并将稳定的多重PCR体系用于56个三角帆蚌紫色选育系的遗传多样性研究。结果表明该群体的平均等位基因数18.75, 平均有效等位基因数为9.010, 平均多态信息含量为0.857, 平均观测杂合度和期望杂合度分别为0.809和0.876, 香农多样性指数为2.422。运用Cervus v3.0 软件对3个三角帆蚌全同胞家系共114个个体进行亲子鉴定, 结果显示, 使用该3组微卫星多重PCR体系进行亲子鉴定准确率为100%。该三角帆蚌微卫星多重PCR应用于三角帆蚌群体遗传多样性分析、亲子鉴定和家系管理等, 可提高工作效率, 降低实验成本。

Abstract: In order to increase the analysis efficiency of microsatellite in Hyriopsis cumingii, 3 groups of 4 multiplex PCRs panels were established from the developed microsatellite labels. The stable multiplex PCR panels were used to analyze the genetic diversities of 56 purple breeding lines of H. cumingii. The results showed that the average number of alleles(A)was 18.75, the effective number of alleles(An)was 9.010, the average of polymorphism information content(PIC)was 0.857, the average observed heterozygosity(Ho)and expected heterozygosity(He)were 0.809 and 0.876, respectively, and Shannon information index(I)was 2.422. The Cervus v3.0 software was used to have parentage assignment for 114 individuals in 3 full-sib families, and the results revealed that accuracy of parentage assignment by this 3 groups of multiplex PCR panels was 100%. Therefore, this multiplex panels can be applied in genetic diversity studies of H. cumingii population, parentage assignment and family management with increased detection efficiency and reduced test cost.
