摘要:

为了了解GPR147基因多态性及其与产蛋性状的关系,本试验以寿光鸡为试验材料,用直接测序的方法检测了寿光鸡该基因5′调控区的SNPs,并与产蛋性状进行了关联分析。结果发现,GPR147基因的5′ 调控区在鸡群中共有11个SNPs位点,其中-593和-579位点的不同基因型在后期(45~56周)产蛋量和56周总产蛋数有显著差异(P<0.05);-593位点TT基因型对应较高产蛋数,-579位点AA基因型对应较高产蛋数。上述两个位点的单倍型分析结果表明,单倍型TA与CG相比,中期(26~44周)产蛋量多了1.5枚(P=0.041 8),后期产蛋量多2.5枚(P=0.032 6),300天产蛋量多1.6枚(P=0.1),56周总产蛋量多4.4枚(P=0.014 4)。综上,GPR147 5′ 调控区存在丰富的SNPs位点,-593和-579位点SNPs及其单倍型对寿光鸡的产蛋性状有显著影响,是具有潜在应用价值的分子标记。

Abstract:

 To investigate the single nucleotide polymorphisms (SNPs) of GPR147 gene and the correlations between SNPs and laying traits,the SNPs in the 5′ regulatory region of GPR147 of Shouguang chicken were detected by direct sequencing method and their associations with laying traits of Shouguang chickens were analyzed.The results showed that there were 11 SNPs loci in the 5′ regulatory region of GPR147 gene detected in the population.The -593 and -579 loci had significant effects on egg production from 45- to 56-week-old and total egg number until 56-week-old (P<0.05).Genotype TT at the -593 locus and AA at -579 locus were associated with higher egg production.Haplotype analysis of the 2 loci showed that hens with haplotype TA laid 1.5,2.5,1.6 and 4.4 eggs more than that with haplotype CG during 26-44 weeks of age (P=0.041 8),45-56 weeks of age (P=0.032 6),the period until 300 days of age (P=0.1) and the total period until 56 weeks of age (P=0.014 4),respectively.In summary,the 5′ regulatory region of the GPR147 has highly polymorphic,SNPs and haplotypes at -593 and -579 loci have significant impacts on the egg number of Shouguang chickens,and they can be used as potential and valuable candidate molecular markers.
