摘要: 选取我国20个地方鸡种共591个个体作为实验材料,采用变性高效液相色谱(DHPLC)技术,在鸡HSP70基因的全序列内进行未知SNPs的筛选,对有变异的色谱峰型分别选取2个个体测序,再将同一对引物的所有测序样本的测序结果进行序列的同源性比较,从而识别和确认鸡HSP70基因的未知SNPs。结果分别在4对引物扩增的PCR产物中检出并确认了10个SNPs:A258G、C276G、C507T、C1040A、G1044A、C1431A、T1476C、G1500A、A1529G、C1722T。

Abstract: In this research, 591 individuals from 20 different Chinese native chicken breeds were studied. By using DHPLC technology Unknown SNPs were detected in the chicken HSP70 gene sequence and for every mutant chromatographic types, 2 individuals were selected to sequence. Homologous analysis was carried out based on the sequence information of samples that amplified from same primer to identity new unknown SNPs. In the PCR products amplified by primer A5, A6, A7 and A4, 10 SNPs sites (A258G, C276G, C507T, C1040A, G1044A, C1431A, T1476C, G1500A, A1529G and C1722T) are detected.

Key words: denaturing high performance liquid chromatography (DHPLC), chicken, HSP70 gene, single nucleotide polymorphisms (SNPs)
