[ Method] cpSSR-PCR amplification system for Jatropha curcas Linn influenced by five factors including Taq DNA polymerase, Mg^2＋ , DNA template, dNTP and primer were optimized from several levels. [ Result] The optimum concentration of 20 μl reaction system was 10 × Buffer, 2.00 mmol/L Mg^2＋ , 2 U/μl Taq DNA polymerase, 0.2 mmol/L dNTP, 0.2 μmol/L primer and 35 ng/μl DNA template. [ Conclusion] The optimum annealing temperature for cpSSR-PCR reaction system is 52 ℃, and the cpSSR reaction system is steady and reproducible.展开更多
