利用自主开发的微卫星标记对中华绒螯蟹(Eriocheir sinensis)进行微卫星多重PCR体系构建,最终成功建立4组多重体系, 每组体系包含4个微卫星位点, 并成功应用于3个家系的亲子鉴定中.结果显示: (1)本研究筛选的16个微卫星标记, 平均观测杂合度为0.8206, 平均期望杂合度为0.8164, 平均多态信息含量为0.7927, 具有丰富的多态性; (2)运用Cervus 3.0软件对已知系谱信息的3个中华绒螯蟹家系共95个子代个体进行亲子鉴定分析, 结果显示, 选用任意两组微卫星多重PCR体系时, 累积实际正确鉴定率均超过94.74%; 使用任意三组微卫星多重PCR体系时, 累积实际正确鉴定率均大于98.95%; 使用四组微卫星多重PCR体系时, 累积实际正确鉴定率达到100%.并且当选用组合1、2和组合3, 或者选用组合1、3和组合4时, 对3个家系的累积正确鉴定率达到了100%, 因此选用这些组合不但可以获得准确的系谱信息, 还能减少工作量, 降低成本.本研究构建的微卫星多重 PCR 体系能为中华绒螯蟹的种群选育和家系管理提供便捷、高效的途径.
Development and application of multiplex PCR panels of microsatel-lites in Chinese mitten crab(Eriocheir sinensis)
In order to increase the analysis efficiency of microsatellites in Chinese mitten crab(Eriocheir sinensis), we report four highly informative, multiplex PCR panels developed from 16 microsatellite markers. The multiplex PCR panels were used to evaluate the genetic diversities and parentage assignment for 95 individuals in 3 families. The results showed that the 16 microsatellite markers screened in this study were rich in polymorphism, for ex-ample the average of observed heterozygosity (Ho) was 0.8206, the average of expected heterozygosity (He) was 0.8164, and the average of polymorphism information content (PIC) was 0.7927. Cervus 3.0 software was used to determine parentage assignment for 95 individuals in 3 families, and the results revealed that the accuracy of par-entage assignment using any 2 groups of multiplex PCR panels was more than 94.74%. When using any 3 groups of multiplex PCR panels, the accuracy of parentage assignment was greater than 98.95%. The accuracy of parentage assignment was greater than 100% using all four multiplex assays. Using the combination of set 1, set 2, and set 3, or the combination of set 1, set 3, and set 4, the accuracy of parentage assignment also reached 100%, so the selection of these combinations of multiplex PCR panels can not only get accurate genealogy information, but also reduce workload and costs. Therefore, these multiplex PCR panels can provide a convenient and efficient way for breeding and family management of E.sinensi.
