摘  要:
运用单因素试验法对影响也门铁ISSR-PCR扩增的各个因素进行了优化,优化体系为:25μL反应体系中,Taq酶浓度0.04 U.μL-1、dNTPs浓度0.18 mmol.L-1、引物浓度0.4μmol.L-1、Mg2+浓度2.0mmol.L-1、模板浓度0.8 ng.μL-1、甲酰胺浓度1.6%、1×buffer,最后用dd H2O补足到25μL。利用优化体系和筛选的引物对也门铁及其嵌合体品种进行了ISSR扩增分析。

摘  要:
The optimization of main influential factors of ISSR reaction system in Dracaena fragrans was studied.The results show that the optimum concentrations of components such as Taq DNA polymerase,dNTPs,primer,Mg2+,template DNA,formamide,10×buffer(without Mg2+),in 25 μL reaction system were 0.04 U·μL-1,0.18 mmol·L-1,0.4 μmol·L-1,2.0 mmol·L-1,0.8 ng·μL-1,1.6%,2.5 μL,respectively.Amplifications of 3 varieties of Dracaena fragrans were achieved by using this optimum system.
