摘要: 研究以5头北京黑猪和5头东北民猪DNA混合池为模板,采用测序的方法研究猪红细胞生成素受体(erythropoietin receptor,EPOR)基因外显子区序列遗传变异。研究结果发现,EPOR基因外显子区共存在3个SNP位点,其中g.1147C>G位于外显子2,可导致第50位氨基酸改变(Leu>Val);g.1645G>A位于外显子3,可导致第92位氨基酸改变(Arg>His);g.4953C>T位于外显子8,为同义突变。经检测,在一个30头的北京黑猪群体中,除g.1147C>G位点外,另外2个位点均处于哈代-温伯格平衡状态。

Abstract: Polymorphisms were screened in exons of porcine erythropoietin receptor(EPOR) gene by resequencing exons using PCR amplification of a DNA pool from 5 Beijing
Black pigs and 5 Min pigs. 3 SNPs, g.1147C>G in exon 2, g.1645G>A in exon 3 and g.4953C>T in exon 8, were detected. In which, g.1147C>G in exon 2 causes an amino acid substitution (Leu>Val) at position 50 (NP_999457), and g.1645G>A in exon 3 causes an amino acid substitution (Arg>His) at position 92. The third SNP, g.4953C>T in exon 8, was a synonymous varibation. Except for g.4953C>T, Hardy-Weinberg equilibriums were found at g.1147C>G and g.1645G>A in 30 Beijing Black pigs.
