摘要

印度本地牛(desi cattle),以其适应性和表型多样性而闻名,代表了宝贵的遗传资源。然而,单一参考基因组往往无法全面捕捉其遗传变异。为解决这一问题,我们通过鉴定和表征非参考新序列(NRNS)构建了本地牛泛基因组。我们测序了来自7个品种的68个基因组,生成了483.5亿条短读序列。利用泛基因组分析(PanGA)流程,我们鉴定出13,065个NRNS(约4100万个碱基对),并在群体中观察到显著变异。大多数NRNS为本地牛特有,与中国瘤牛泛基因组的重叠极少(4.1%)。约40%的NRNS在牛属(Bos)中具有祖先起源,且富集于基因区域,提示其具有功能作用。这些序列与影响产奶量等性状的数量性状位点相关。泛基因组方法提高了读序列比对精度,减少了假阳性单核苷酸多态性(SNP)的检出,并发现了新的遗传变异,从而加深了对本地牛基因组学的理解。
