摘要: 试验旨在寻找影响京海黄鸡γ-干扰素(IFN-γ)水平的分子标记。本研究以京海黄鸡核心群母鸡为基础,测定了血清中INF-γ的浓度,利用简化基因组测序技术进行全基因组关联分析(GWAS),检测与INF-γ浓度相关的SNPs位点。结果共检测到1个在基因组水平上与其潜在显著相关的SNP位点,并达到染色体显著水平。该SNP位于2号染色体上MYOM1基因内部。使用GO数据库对该基因的细胞组分、分子功能和参与的生物进程进行分析,由结果推断MYOM1基因可能为影响京海黄鸡细胞因子INF-γ水平的重要候选基因。

Abstract: In order to reveal the molecular marker that influenced Jinghai Yellow chicken's INF-γ level.This research was based on female Jinghai Yellow chicken in core group and had measured the INF-γ concentration in serum.Genome-wide association study was carried out using specific-locus amplified fragment sequencing technology to detect SNP associated with this trait.Finally,one SNP that potentially associated with INF-γ was detected and it reached the chromosome significant level.This SNP was located in MYOM1 gene on chromosome 2.The cellular component,molecular function and biological process were analyzed using GO database.Furthermore,the result showed that MYOM1 gene was an important candidate genes affecting INF-γ in Jinghai Yellow chicken.

Key words: SLAF-seq; Jinghai Yellow chicken; INF-γ; genome-wide association study
