摘要: 识别野生动物群体内潜在影响动物表型变异的相关基因是进化遗传学研究的主要目的,而动物毛色是研究动物被毛表型形成遗传机制的最佳模型之一。应用Illumina公司提供的猪60 k SNP基因芯片对选取的62只不同被毛表型的野猪个体进行基因分型,利用SNP分析结果,通过对照全基因组关联分析(GWAS)识别影响野猪被毛表型差异的相关变异。结果表明,识别了6个与野猪被毛表型相关的基因组变异区域,分别位于SSC1(ALGA0001794,ASGA0006416)、SSC2(ASGA0011559)、SSC6(H3GA0018683)、SSC7(ASGA0035535)和SSC14(ASGA0060641);最显著相关的SNP(ALGA0001794)位于猪1号染色体上(SSC1)的27 899 596-27 899 696 bp区间(P=2.96×10-(-5))。该研究初步鉴定了6个与野猪毛色性状相关的易感位点,为进一步研究野猪不同毛色性状的形成机制提供了基础。

Abstract: To identify the genes that potentially influencing the phenotypic characteristics variation of wild animals was the main objective of evolutionary genetics related research. Coat color was one of the optimum models that were commonly used in investigation of genetic mechanism associated with formation of animal coat traits. In this study, genetic typing test of 62 wild boars with varied coat traits was conducted by using Illumina pig 60 k SNP chips. Based on the SNP typing results, the genes associated with the variation of wild boars coat traits were identified by genome-wide association study(GWAS). We found 6genome variation areas associated with wild boars coat traits, locating in SSC1(ALGA0001794,ASGA0006416), SSC2(ASGA0011559), SSC6(H3GA0018683), SSC7(ASGA0035535)and SSC14(ASGA0060641), respectively. The most significantly correlated SNP was found in SSC1 and located in the region of 27 899 596-27 899 696 bp(P =2.96 ×10^-5). Six susceptibility gene loci associated with coat color traits of wild boars were preliminarily identified, which provides a basis for the genetic mechanism associated with formation of varied coat color traits of wild boars.
