摘要
对ISSR-PCR扩增荔枝基因组DNA的主要影响因子进行了筛选和分析。试验结果表明:20μl的反应体系中采用20ng的模板DNA,0.15μmol/LISSR引物、1.25U Taq DNA聚合酶,0.15μmol/L dNTP,以及50~54℃的复性温度为荔枝1SSR-PCR扩增条件的最佳选择。
The factors influencing ISSR-PCR to analyze the genetic divergence in Litchi (Litchi chinensis Sonn.) were investigated.Comparative experiments on the concentrations of template DNA; ISSR primer, Taq DNA polymerase and the annealing temperature were carried out. The results showed that the optimum reaction condition of ISSR was 20ng DNA template, 0.15μLmol/L ISSR primer, 1.25UTaq DNA polymerase, 0.15μmol/L dNTPand annealing temperature of 50-54℃ in each reaction system of 20μl.
