摘要
以槟榔为试验材料,用改良的CTAB法提取基因组DNA,并设置不同梯度分别对每个PCR反应因子做了相应的试验。结果表明:改良的CTAB法提取的槟榔基因组纯度高、质量好;同时,建立了适合槟榔ISSR-PCR反应体系,即20μLPCR反应体积中,模板DNA浓度为30ng/μL,Mg2+浓度为2.5mmol/L,TaqDNA聚合酶1.0U,dNTPs浓度为0.4mmol/L,引物为浓度为0.8μmol/L。
The high purity and quality genomic DNA of Areca catechu L.was extracted by the modified CTAB method,which was set different gradients for each PCR reaction factor to do experiment.Meanwhile,the most suitable ISSR-PCR reaction system for Areca catechu L.was established,which is as below:30 ng/μL of template DNA,2.5 mmol/L of Mg2+,1.0 U Taq DNA polymerase,0.4 mmol/L of dNTPs and 0.8 μmol/L of primer within total 20 μL of reaction solution.
