| 摘 要： | 以乌江流域中华倒刺鲃(Spinibarbus sinensis)为材料,构建了中华倒刺鲃微卫星富集文库。以乌江彭水电站所采集的32个个体的基因组DNA为模板,进行PCR扩增,结果筛选出8个多态性微卫星位点,其等位基因数4~10,多态信息含量0.6072~0.8515;观测杂合度0.5625~1.0000,期望杂合度0.6791~0.8795,Hardy中华倒刺鲃微卫星标记筛选及特征分析Weinberg平衡偏离指数-0.2009~0.3805;卡方检验结果表明,3个位点不同程度地偏离了Hardy中华倒刺鲃微卫星标记筛选及特征分析Weinberg平衡(P<0.05);各位点两两之间不存在显著的连锁不平衡现象。

| Abstract: | The microsatellite markers of Spinibarbus sinensis were isolated in this study.A library of partial small size fractionated genomic DNA was constructed with the S.sinensis in Wujiang river.Eight microsatellite loci were isolated and characterized.These loci showed high levels of genetic polymorphism testing on 32 individuals sampled from Wujiang river.The number of alleles per locus ranged from 4 to 10.PIC changed from 0.6072 to 0.8515.The observed(Ho)and expected(He)heterozygosities were 0.5625 to 1.0000 a... |
