摘要:
利用崇仁麻鸡差异性状的重测序结果,将生长分化因子(GDFs)基因家族作为候选基因,筛选与崇仁麻鸡生长性状相关的多态位点。结果发现,GDF-2、GDF-8和GDF-10基因的多态位点对崇仁麻鸡的生长性状有着显著或极显著的影响。单倍型分析结果显示,GDF-2和GDF-10基因的单倍型H3H3为劣势单倍型组合可以选择淘汰。研究结果表明,GDFs基因家族候选基因对崇仁麻鸡的生长性状有一定的影响。

Abstract:
In this study, the growth differentiation factor (GDFs) gene family was used as candidate genes to screen polymorphic loci related to growth traits of Chongren partridge Chicken based on the results of re-sequencing. The results showed that the SNPs of GDF-2, GDF-8 and GDF-10 genes had significant or extremely significant effects on the growth traits of Chongren partridge Chicken. The haplotype analysis showed that the haplotypes H3H3 of GDF-2 and GDF-10 genes were inferior haplotypes and could be eliminated. The results showed that GDFs gene family had some effects on growth traits in Chongren partridge chicken.
Key words:  chongren partridge chicken  GDFs gene family  growth trait  molecular marks
