Abstract:
Taking Rhododendron simsii as materaial,the orthogonal test system was adopted to establish the ISSR-PCR amplification system and optimize amplification condition for Rhododendron simsii.The effect of template DNA concentration,ISSR primer concentration,dNTPs concentration,Taq DNA polymerase concentration,and Mg2+ concentration on amplification results of ISSR-PCR were studied.The results showed that the optimal 20 μL ISSR-PCR reaction system including 60 ng genomic DNA,0.60 μmol/L primer,0.50 μmol/L dNTPs,30 U/mL Taq DNA polymerase,and 0.6 mmol/L Mg2+.This system also gave stable and reliable results in other ISSR primers.Therefore,the established ISSR-PCR reaction system would be helpful in the following genetic diversity analysis,the construction of ISSR fingerprints,phylogenetic analysis of R.simsii.
