摘要: [目的]挖掘影响绵羊生长性状的候选基因,为绵羊品种的选育改良奠定基础。[方法]采用琼脂糖凝胶电泳和测序技术检测PPARGC1A基因的InDel(插入/缺失)位点在湖羊、杜泊羊以及小尾寒羊群体中的多态性,并对PPARGC1A基因的多态性与绵羊生长性状之间的关联性进行分析。[结果]PPARGC1A基因在3个绵羊品种中均检测到3种基因型,即II型、ID型和DD型。湖羊、杜泊羊以及小尾寒羊的II基因型频率分别为0.328、0.209、0.563,ID基因型频率分别为0.432、0.488、0.406,DD基因型频率分别为0.240、0.302、0.031。关联分析表明,PPARGC1A基因与湖羊的体高、背高和臀端高有显著(P<0.05)关联性;PPARGC1A基因与小尾寒羊的体长有显著(P<0.05)关联性;PPARGC1A基因与杜泊羊的各生长性状无显著(P>0.05)关联性。[结论]PPARGC1A基因对湖羊和小尾寒羊的部分生长性状有影响,可以作为湖羊和小尾寒羊遗传杂交改良的重要功能候选基因。

Abstract: [Objective] To explore candidate genes influencing sheep growth traits and provide a basis for genetic improvement in sheep breeding. [Methods] Agarose gel electrophoresis and sequencing were used to detect the polymorphism of PPARGC1A gene InDels (insertions/deletions) in Hu sheep, Dorper sheep and Small-tailed Han sheep, and the association between the polymorphism of PPARGC1A gene and sheep growth traits was analyzed. [Results] Three genotypes (II, ID and DD) of the PPARGC1A gene were detected in all three sheep breeds. The II genotype frequencies of Hu sheep, Dorper sheep, and Small-tailed Han sheep were 0.328, 0.209 and 0.563, respectively. The ID genotype frequencies were 0.432, 0.488 and 0.406, respectively, while the DD genotype frequencies were 0.240, 0.302 and 0.031, respectively. Association analysis showed a significant association(P<0.05) between the PPARGC1A gene and body height, back height and buttock height in Hu sheep, as well as body length in Small-tailed Han sheep (P<0.05). No significant associations were observed in Dorper sheep (P>0.05). [Conclusion] The PPARGC1A gene had an impact on some growth traits in Hu sheep and Small-tailed Han sheep, and could be used as an important functional candidate gene for crossbreeding improvement in Hu sheep and Small-tailed Han sheep.
