摘要: 目的 人工繁育猕猴所面临的最大问题是繁殖群体过小所导致的近亲交配, 为了防止近亲交配带来的不利影响,采用微卫星分子标记建立猕猴人工繁殖种群的准确系谱非常重要。方法 本研究采用荧光标记引物PCR和毛细管电泳分型的方法将筛选出的14个微卫星位点应用于64只猕猴人工繁育种群,并通过个体鉴别、亲子鉴定以及群体遗传结构分析的方法对其进行评价。结果 这些位点在猕猴中均属于高度多态位点,其中7个位点的期望杂合度(He)和多态信息含量(PIC)值均在0.8以上,14个位点的累计个体鉴别率(CPI)为1.21×10-18,单亲已知时累积排除率(CPE2)和双亲未知时累积排除率(CPE1)可达0.9999和0.9985。结论 这些位点能够对猕猴种群进行准确的个体鉴别、亲子鉴定和群体遗传学参数计算,是可靠、高效的分子标记,或可应用于猕猴人工饲养种群的遗传学管理。

Abstract: Objective Inbreeding is the big problem in captive colonies of rhesus macaques.To preserve genetic variability, the exact pedigree must established by genetic markers. Methods Fourteen autosomal short tandem repeat (STR) loci with high information content were used to 64 rhesus macaques by fluorescently-labeled primer polymerae chain reaction (PCR) and capillary electrophoresis typing. Then, these loci were evaluated by unique genetic characterization, parentage determination, and estimation of parameters. Results Seven of the 14 markers have high gene diversity (He) and polymorphic information content (PIC)(>0.8), the combined probability of genetic identity (CPI) at all loci is 1.21E-18, and the combined probability of no-parent exclusion (CPE1) or single parent exclusion (CPE2) at all loci can reach 0.9985 and 0.9999 respectively. Conclusion These markers are reliable and highly informative genetic markers, can provide for powerful parentage determination, unique genetic characterization, and accurate estimation of parameters, which are all useful for genetic management of rhesus macaques.
