摘要: 旨在研究脂联素基因(Adiponectin)在鸭群体中的遗传变异情况。以北京鸭、高邮鸭、莆田黑鸭、连城白鸭、绍兴鸭、攸县麻鸭和建昌鸭为材料,运用连接酶检测反应(PCR-LDR)的方法对Adiponectin基因外显子2上T523C SNP位点进行基因分型,并分析该位点在群体中的基因频率、基因型频率和Hardy-Weinberg平衡情况。结果显示,Adiponectin基因T523C位点在7个鸭种中均检测到TT、TC和CC 3种基因型。在莆田黑鸭、绍兴鸭、攸县麻鸭、建昌鸭、北京鸭和高邮鸭中,杂合型占优势,仅在连城白鸭中,TT型占优势。莆田黑鸭、连城白鸭、攸县麻鸭和北京鸭等位基因T的频率大于等位基因C的频率,绍兴鸭、建昌鸭和高邮鸭等位基因C的频率大于等位基因T的频率。7个鸭种在Adiponectin基因T523C位点均处于Hardy-Weinberg平衡状态(P>0.05)。

Abstract: It was to study the Adiponectin gene polymorphism in duck population. The single nucleotide polymorphism(SNP) of Adiponectin gene T523C SNP on exon2 of Adiponectin was investigated in seven national duck breeds, including Beijing duck, Gaoyou duck, Putian black duck, Liancheng white duck, Shaoxing duck, Youxian Sheldrake and Jianchang duck by PCR-LDR method. And the gene frequency and genotype frequency distribution was analyzed by Hardy-Weinberg equilibrium. Results showed TT, CC and TC genotypes of Adiponectin gene T523C were all detected in seven populations. TC was dominant in six populations except Liancheng white duck, TT was dominant only in Liancheng white duck. T gene frequency was higher than C gene frequency in Beijing duck, Putian black duck, Liancheng white Duck and Youxian Sheldrake. At the other hand, C gene frequency was higherter than T gene frequency in Gaoyou duck, Shaoxing duck and Jianchang duck. The gene at T523C of Adiponectin gene is in genetic balance in 7 duck populations (P>0.05), which will provide an experimental basis on duck molecular genetics.
