摘要:

采用L16(45)正交试验对玫瑰SRAP-PCR反应体系进行优化。结果表明,各因素对PCR反应的影响程度从大到小依次为:Taq酶,dNTPs,引物,Mg2+,模板;建立了玫瑰SRAP-PCR反应最佳体系(25μL)为Mg2+ 2.0 mmol/L,dNTPs 0.20 mmol/L,Taq酶1.5U,引物0.25 μmol/L,模板 1.0 ng/μl;采用不同的模板和引物对体系进行验证,表明该体系适合于玫瑰的SRAP-PCR反应

Abstract:

The orthogonal design was employed to optimize SRAP-PCR amplification .The results showed that the order of factors which affect on the result of PCR are Taq polymerase ,primers ,dNTPs , Mg2+ and DNA . A suitable SRAP-PCR system for Rose rugosa is that total 25μL reaction system containing 2.0 mmol/L Mg2+ , 0.20 mmol/L dNTPs , 1.5U Taq polymerase , 0.25 μmol/L primers and 1.0 ng/μl DNA. Use other primers and DNAs to test the system , the results showed that the system can be used in Rose rugosa.
