摘要:

旨在探究BACE2基因中的单核苷酸多态性(SNPs)与娘亚牦牛生长性状之间的相关性,为改善牦牛的生长性能提供潜在的分子标记位点。基于重测序数据,在娘亚牦牛BACE2基因中检测到2个SNP位点(g.47,411T>C和g.81,108T>C),对上述的2个SNPs进行遗传多态性分析,并且分析这2个SNP位点与牦牛生长性状之间的相关性。遗传多态性分析发现,g.47,411T>C和g.81,108T>C位点为低度多态位点。关联结果表明,g.47,411T>C的TT基因型牦牛个体的体质量和胸围性状显著高于CC型牦牛个体,且TT基因型牦牛个体的体长显著高于TC和CC型牦牛个体。g.81,108T>C位点的TT基因型牦牛个体的体质量和胸围显著高于CC型牦牛个体,TT基因型的牦牛个体的体长性状显著高于TC型牦牛个体,且TC型牦牛个体的体长显著高于CC型牦牛个体。综上所述,BACE2基因g.47,411T>C和g.81,108T>C位点对娘亚牦牛的生长性状具有显著影响。

Abstract:

This study aimed to investigate the association between single-nucleotide polymorphisms(SNPs)in BACE2 gene and growth traits of Niangya yak,and to provide potential molecular markers for improving the growth performance of yak.Based on the re-sequencing data,two SNP sites(g.47,411T>C and g.81,108T>C)were detected in the BACE2 gene of Niangya yak.The genetic polymorphism of the two SNPs and the correlation between the two SNPs and growth traits of yaks were analyzed.Genetic polymorphism analysis showed that g.47,411T>C and g.81,108T>C loci were low polymorphic loci.The correlation results showed that the body weight and chest circumference traits of TT yaks with g.47,411T>C were significantly higher than those of CC yaks,and the body length of TT yaks was significantly higher than that of TC and CC yaks.The body weight and chest circumference of TT yaks with g.81,108T>C locus were significantly higher than those of CC yaks.The body length of TT yaks was significantly higher than that of TC yaks,and the body length of TC yaks was significantly higher than that of CC yaks.In conclusion,the g.47,411T>C and g.81,108T>C loci of the BACE2 gene had significant effects on growth traits of Niangya yak.
