    摘要:

    目的 建立封闭群实验鹌鹑微卫星DNA遗传检测方法。方法 通过文献检索,筛选鹌鹑微卫星位点,利用种间转移法,在鹌鹑近缘物种—鸡和鸭筛选适合鹌鹑的微卫星DNA位点。提取鹌鹑肝组织DNA作为模板,并通过PCR扩增以及琼脂糖凝胶电泳技术,对相应的位点进行筛选。最后根据所选微卫星位点扩增情况、等位基因数目和多态性等,筛选出适用于鹌鹑遗传质量检测的微卫星位点组合并建立检测方法。结果 初步确定适用于封闭群实验鹌鹑遗传检测的23个微卫星位点组合。结论 初步建立了实验鹌鹑的遗传质量检测方法。

    Abstract:

    Objective To establish a genetic monitoring method for laboratory quails. Methods Quail microsatellite loci were screened through literature search, and microsatellite DNA loci suitable for quail were screened by interspecific transfer method in quail closely related species, chickens and ducks. Quail liver tissue DNA was extracted as a template, and the corresponding loci were screened by PCR amplification and agarose gel electrophoresis. Finally, based on the amplification of the selected microsatellite loci, the number of alleles, and polymorphism, microsatellite loci combinations for quail genetic quality detection were selected and detection methods were established. Results We preliminary determined 23 microsatellite loci for genetic monitoring of closed-colony laboratory quails. Conclusion A genetic monitoring method for laboratory quails is preliminary established.
