五指山猪FUT1基因SNP检测及生物信息学分析

SNP Detection and Bioinformatics Analysis of FUT1 Gene of Wuzhishan Pig

为获得五指山猪FUT1基因序列并分析其基因结构,检测FUT1基因中的单核苷酸多态性(SNP)位点在五指山猪群体中的分布情况,本试验利用PCR扩增猪FUT1基因组序列,通过基因测序寻找该基因中的SNP位点,使用PCR-RFLP方法对120头五指山猪进行了FUT1基因型检测,并运用生物信息学方法对FUT1基因序列进行分析。在猪FUT1基因组中共发现两个单碱基突变,分别位于编码区(A+307G)和3′非翻译区(A+1 856C);在FUT1基因A+307G突变位点上,五指山猪均为GG基因型;此外,FUT1基因启动子区域和第2外显子处存在CpG岛。本研究成功获得五指山猪FUT1基因序列信息,为下一步五指山猪FUT1基因的功能研究奠定基础。

This study was aimed to detect FUT1 gene,analyze its structure,and reveal the distribution of SNP in Wuzhishan pig.FUT1 gene was amplified by PCR.Then the gene mutation was identified by sequencing.PCR-RFLP method was used to detect the FUT1 gene of 120 Wuzhishan pigs.Some characters of FUT1 gene were analyzed by bioinformatics tools.Two mutations were detected in the FUT1 genomic fragment,one in the coding region（A＋307G）and the other in the3′regulatory region（A＋1 856C）.At the A＋307Glocus of coding region in FUT1 gene,100% of Wuzhishan pigs were GG genotype.In addition,bioinformatics analysis revealed that FUT1 gene promoter and the second exon region contained CpG islands.In this study,we obtained the sequences of FUT1 gene which laid a foundation for further studying its functions in Wuzhishan pig.
