摘要/Abstract

摘要： 试验旨在研究猪多潜能性维持因子5(developmental piuripotency associated 5,Dppa5)基因的遗传多态性及其与母猪繁殖性状的遗传效应。以长白猪和大白猪为试验群体,采用PCR-RFLP、克隆测序等方法分析检测猪Dppa5基因的多态性并对其与母猪产仔性能进行关联分析。结果表明,猪Dppa5基因外显子上存在2个错义突变位点:g.363 T> C和g.844 G> T;猪Dppa5基因g.363 T> C 位点对初产大白猪的总产仔数有极显著影响(P< 0.01),对经产大白猪、长白猪的产活仔数有显著影响(P< 0.05);g.844 G> T位点对经产长白猪和大白猪的总产仔数有显著影响(P< 0.05)。综合结果分析,Dppa5多态位点对猪的繁殖性能存在影响,可作为潜在的遗传标记,为猪的分子育种提供参考。

Abstract: The purpose of this study was to detect the genetic variation of the porcine developmental piuripotency associated 5 (Dppa5) gene and its association with reproductive performance in sow.PCR-RFLP and sequencing methods were used to detect SNPs and analyze its association with reproductive performance in Large White and Landrace sows.The results showed that two missense mutations g.363 T> C and g.844 G> T were detectd in exon of porcine Dppa5.SNP g.363 T> C affected total number born highly significantly in primiparous Large White sow (P< 0.01) and affected litter size and number born alive significantly in Large White and Landrace sows (P< 0.05).SNP g.844 G> T showed a significant impact on total number born in multiparous Landrace and Large White sows (P< 0.05).The results suggested that the SNPs of Dppa5 gene impacted reproductive performance of sows and could be genetic markers.
