摘要
为分析我国家养雉鸡遗传背景和起源进化关系,采用高通量简化基因组测序方法对我国家养6个雉鸡群体(美国七彩雉鸡、蒙古雉鸡、黑化雉鸡、白羽雉鸡、绿雉鸡、申鸿七彩雉)的分类起源关系进行分析。结果表明:获得雉鸡Clean base数据分别为330.44×10^(6)Gb,340.64×10^(6)Gb,348.50×10^(6)Gb,291.67×10^(6)Gb,286.44×10^(6)Gb和324.98×10^(6)Gb,Q20≥92%、Q30≥85%,GC分布正常,共挖掘到50078个有效SNP位点。通过系统进化树、主成分和群体遗传结构分析,6个雉鸡种群可分为两大类,申鸿七彩雉、黑化雉鸡、白羽雉鸡、绿雉鸡和美国七彩雉鸡为一类,蒙古雉鸡单独为一类。研究揭示家养雉鸡种群在长期的养殖过程中存在基因交流。
This study aimed to analyze genetic background and evolution of breeding common pheasant.Chinese ringnecked pheasant,Mongolian pheasant,black pheasant,white pheasant,green pheasant and Shenhong pheasant were analyzed with the high throughput simplified genomic sequencing method.The results showed that 330.44×10^(6) Gb,340.64×10^(6) Gb,348.50×10^(6) Gb,291.67×10^(6) Gb,286.44×10^(6) Gb,324.98×10^(6) Gb of clean base data and 50078 SNPs from 60 domestic pheasant populations by GBS,which were Q20≥92%,Q30≥85% were obtained.The domestic pheasant populations in China could be divided into two groups by the phylogenetictree,PCA and population genetic structure,of which Shenhong pheasant,black pheasant,white pheasant,green pheasant and Chinese ring-necked pheasant were lumped together and Mongolian pheasant was another one.This study revealed that gene exchage occured in common pheasant populations in the long-term breeding process.
