【摘要】 牛基因组的遗传标记图谱上有3 800多个分子标记座位,它为寻找某些影响显著的数量性状位点提供了便利的条件。其中研究最为深入的有:抑肌素基因、生长激素基因、生长激素受体基因、胰岛素样生长基因子1基因、脑垂体特异性转录因子1基因和瘦蛋白基因。其他的候选基因也鉴定出来并定位到特定的染色体区域上。综述了几种侯选基因在牛育种中的研究进展。更多还原

【Abstract】 The bovine marker genome map is covered by over 3?800 marker loci.This facilitates its extensive use in searching for genes with significant effects on quantitative trait variation.Among them the most intensively studied are genes responsible for the myostatin,the growth hormone,the growth hormone receptor,the insulin-like growth factor 1,the pituitary-specific transcription factor 1,and leptin.Other candidate genes were also identified and assigned to specific chromosome regions.In this review,Advance on Some Candidate Genes in Beef Cattle Breeding was briefly introduction.更多还原
