摘要:

家禽的羽色遗传一直是炙手可热的研究课题,因为羽色是禽类一种重要的质量性状。本研究利用聚丙烯凝胶电泳技术对不同羽色的4个鹌鹑群体(中国黄羽鹌鹑、黑羽鹌鹑、朝鲜鹌鹑、北京白羽鹌鹑)进行野灰相关蛋白基因(agouti-related protein,Agrp)外显子Ⅰ的多态性检测,探讨Agrp外显子Ⅰ与鹌鹑羽毛颜色的关系,为鹌鹑的育种及生产提供参考。结果表明,Agrp外显子Ⅰ在中国黄羽鹌鹑、黑羽鹌鹑、朝鲜鹌鹑、北京白羽鹌鹑群体中都检测到了2个等位基因,分别用A和B表示。等位基因A在北京白羽鹌鹑中的基因频率最高,达到了0.9500。B等位基因在朝鲜鹌鹑中的频率最高,达到了0.3392,在北京白羽鹌鹑中的基因频率最低,只有0.0500。基因型AA在北京白羽鹌鹑中的基因型频率最高(0.9500),在朝鲜鹌鹑和黑羽鹌鹑中最低(0.4286)。基因型AB在北京白羽鹌鹑中没有出现。测序发现,在黑羽鹌鹑和朝鲜鹌鹑中有AG的杂合位点,而在北京白羽鹌鹑中只有G位点。推测Agrp外显子Ⅰ的AB基因型(或B等位基因)与鹌鹑的黑羽色可能有一定关系。

Abstract:

The poultry feather color inheritance has been a hot research topic, because the feather color is a kind of important quality character.In this study, we used polyacrylamide gel electrophoresis to detect the polymorphisms of four quail populations of different feather color (China Yellow quail, Black quail, Korean quail, Beijing White quail) of agouti-related protein gene (Agrp) exon Ⅰ, so as to investigate the relationship of Agrp exon I with quail plumage color, and to provide reference for the breeding and production of quail.The results showed that two alleles were detected in the Agrp exon Ⅰ of China Yellow quail, Black quail, Korean quail, Beijing White quail populations,and expressed by A and B, respectively. Frequency of allele A in Beijing White quail was up to 0.9500. The frequency of B allele in Korean quail was the highest, reaching 0.3392, in Beijing White quail genes in the lowest frequency is only 0.0500. The genotype frequency of AA genotype in Beijing White quail was the highest (0.9500), the lowest in Korean quail and Black quail (0.4286). BB genotype was not observed in Beijing White quail. We speculated that it may have a certain relationship between Agrp exon Ⅰ B allele and feather color of quail.
