摘要: 采用PCR-SSCP和DNA测序技术对2个江苏地方山羊品种的心脏型脂肪酸结合蛋白(heart fatty acid binding protein,H-FABP)基因进行单核苷酸多态性(SNP)检测和群体遗传学分析。结果表明,在所扩增的片段中,仅在H-FABP基因外显子2的第132位检测到G/C碱基突变,形成GG和GC基因型,2个山羊群体均是纯合GG基因型占主导优势,且该位点处于Hardy-Weinberg平衡状态;黄淮山羊群体的杂合度、有效等位基因数和多态信息含量指标均高于长江三角洲白山羊群体,表明其群体内的遗传变异程度相对较大、遗传多样性也更为丰富。

Abstract: PCR-SSCP and DNA sequencing approaches were applied to assess the single nucleotide polymorphisms (SNPs) and analyze the population genetics of heart fatty acid binding protein (H-FABP) gene of two goat breeds in Jiangsu province. The results showed that only the 132 G/C mutation was detected at the H-FABP gene exon 2 of the amplified fragments, with the formation of GG and GC genotypes. Homozygous GG was the dominant genotype of two goat groups, and the locus was at Hardy-Weinberg equilibrium. Heterozygosity, effective number of alleles and polymorphism information content of Huanghuai goat population was higher than the Yangtze River Delta white goat populations, indicating a relatively large degree of genetic variation and more abundant genetic diversity within population.

Key words: goat; H-FABP gene; SNPs; PCR-SSCP
