NCOA1基因多态性与邵伯鸡父系公鸡精液品质相关性分析

采用PCR-SSCP技术检测优邵伯鸡父系公鸡NCOA1基因的SNPs,并分析其与精液品质的关联性.结果表明,第3外显子区域10155007位点发生了T→A突变,检测到AA、AB、BB 3种基因型;第10外显子区域108273257位点发生了T→C突变,检测到SS、ST、TT 3种基因型; 第12外显子区域108273423位点发生了C→T突变,检测到CC、CD、DD 3种基因型.AA型个体的精液量显著高于BB型个体(P<0.05),精子密度显著高于AB型个体(P<0.05),但AA型个体与BB型个体间精子密度无显著差异(P>0.05).CC、CD、DD型个体间精液量差异均不显著(P>0.05),但CC型个体的精子密度显著高于DD型个体(P<0.05).SS、ST、TT基因型个体间的精液量及精子密度均无显著差异(P<0.05).上述所有基因型个体间的精子畸形率及精子活力差异均不显著(P>0.05).AACC基因组合型个体的精液品质最好,其在精液量、精子密度方面均显著地优于BBDD基因组合型个体(P<0.05).研究结果显示,NCOA1基因可能是影响公鸡精液品质性状的主效基因或与控制该性状的主效基因连锁,能够作为候选基因用于精液品质的分子标记辅助选择.

Association between SNPs of NCOA1 and semen quality in male line rooster of Shaobo commercial breed

Single nucleotide polymorphisms(SNPs) of nuclear receptor co-activator1gene(NCOA1) of sire line of Shaobo commercial breed were detected by using PCR-SSCP and sequencing reaction and its associations with semen quality was done.Three SNPs were detected;T/A substitution at position 10155007 in exon 3 and resulted in 3 genotypes of AA,AB and BB;C/G substitution at position 108273257 in exon 10 and resulted in 3 genotypes of CC,CD and DD;C/T substitution at position 108273423 exon 12 and 3 genotyes of SS,ST an...
