摘要: 本研究旨在加速分子标记在黑羽鹌鹑遗传育种等方面的应用,开发黑羽鹌鹑的EST-SSR标记。随机选取100只黑羽鹌鹑,心脏采血2mL,采用生物信息学方法开发黑羽鹌鹑的EST-SSR新标记,并检测EST-SSR标记在黑羽鹌鹑群体中的多态性。结果显示,在黑羽鹌鹑中成功的开发出了6个EST-SSR标记,EST-SSR标记检测到的观测等位基因数为2~6个,6个EST-SSR标记在黑羽鹌鹑的平均多态信息含量(PIC)为0.4962,平均期望杂合度(He)为0.5759。6个EST-SSR标记中P1和P2个为高度多态标记,其他4个EST-SSR为中度多态标记。新开发的6个EST-SSR标记可用于黑羽鹌鹑的遗传多样性分析,6个EST-SSR标记与鹌鹑的糖类代谢、黑色素的合成等有关系,但具体的机理还有待进一步分析。

Abstract: The purpose of this study was to accelerate the application of molecular markers in genetic breeding and other aspects of Black quail to develop EST-SSR markers for Black quail.100 Black quail were randomly chosen and blood samples were collected to develop EST-SSR new markers and determined the genetic polymorphism using bioinformatics.The results showed that there were 6 EST-SSR markers in the Black quail, the number of observed alleles in EST-SSR was 2 to 6.The average PIC of 6 EST-SSR markers in the Back quail was 0.4962 and the average He was 0.5759.Markers P1 and P2 were highly polymorphic markers among 6 EST-SSR and the rest EST-SSR markers were moderately polymorphic markers.These developed markers could be used for genetic diversity analysis of Black quail and the EST-SSR markers had some relationship with the carbohydrate metabolism, synthesis of melanin in Black quail, but the mechanism needed the further analysis.
