实验用鹌鹑遗传检测方法的初步建立

Establishment of a genetic monitoring method for laboratory quails

目的建立封闭群实验用鹌鹑微卫星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用鹌鹑遗传检测的23个微卫星位点组合。结论初步建立了实验用鹌鹑的遗传质量检测方法。

Objective To establish a genetic monitoring method for laboratory quails.Methods Quail microsatellite loci were searched in the literature,and microsatellite DNA loci suitable for quails were screened by an interspecific transfer method in closely related species,namely chickens and ducks.Quail liver DNA was extracted as a template,and the corresponding loci were screened by PCR amplification and agarose gel electrophoresis.On the basis of amplification of the selected microsatellite loci,the number of alleles,polymorphisms,and microsatellite loci combinations for quail genetic quality detection were selected and detection method were developed.Results We preliminary determined 23 microsatellite loci for genetic monitoring of closed⁃colony laboratory quails.Conclusions A genetic monitoring method for laboratory quails was preliminary developed.
