摘要
采用正交设计对影响枇杷ISSR-PCR的模板DNA、dNTPs、Primer、Taq酶及Buffer(含Mg2+)进行优化。试验结果表明:20μL反应体系中,含模板DNA5ng、dNTPs0.25mmol/L、Primer0.25μmol/L、Taq酶0.5U和10×Buffer(含Mg2+)3μL。此外,从95条ISSR引物中筛选出11条具有丰富的多态性位点的引物,同时优化各引物退火温度。
The factors of template DNA, dNTPs, Primer, Taq polymerase and Buffer (containing Mg2+), greatly influencing ISSR-PCR of loquat, were optimized by orthogonal design. The result shows that the optimum amplification condition of ISSR-PCR is DNA template 5 ng, dNTPs 0.25 mmol/L, Primer 0.25 μmol/L,Taq Polymerase 0.5 U and 10×Buffer (contain Mg2+) 3 μ in 20 μL reaction volumes. Besides, 11 ISSR primers has been obtained with high stability and polymorphism simultaneity obtained for ISSR-PCR annealing temperature from 95 ISSR primers.
