摘要:

根据GenBank中登录的猪红细胞生成素受体(erythropoictin receptor,EPOR)基因mRNA序列(登录号:AF274305)和其基因组序列(登录号:EU407778)设计8对引物,以10头北京黑猪和10头大白猪DNA混合池为模板,采用测序的方法研究猪EPOR全基因序列的遗传变异。研究结果发现,EPOR基因长约5.2 kb,含有1个5′UTR、8个外显子、7个内含子及1个3′UTR。经混合DNA池测序,共在内含子区发现9个SNP位点:g.705G>T位于内含子1;g.1450C>T 位于内含子2;g.2373C>T 位于内含子4;g.2882C>T、g.3035A>G、g.3132A>T、g.3295C>T、g.3942C>T、g.4106G>A位于内含子6,为进一步研究EPOR基因与产仔性状的关联奠定了基础。

Abstract: In this study, 8 pair primers were designed based on erythropoietin receptor (EPOR) RNA (AF274305) and DNA (EU407778) sequences in porcine which were submitted on GenBank. Genetic variation was analyzed by sequencing using a DNA pool from 10 Beijing Black pigs and 10 Large white pigs. The results showed that the porcine EPOR gene contains one 5′untranslated region (UTR), eight exons, seven introns, and one 3′UTR, covering at least 5.2 kb of genomic DNA. 9 new single nucleotide polymorphisms (SNPs) were identified: g.705G>T in intron 1, g.1450C>T in intron 2, g.2373C>T in intron 4, and g.2882C>T, g.3035A>G, g.3132A>T, g.3295C>T, g.3942C>>T and g.4106G>A in intron 6.
