본 실험결과 느타리버섯속에서의 재현성 있는 최적 RAPD 조건은 $50;{mu}l$ 반응액에서 80 ng template DNA, 30 pmole primer, $200;{mu}M$ dNTP, 2 mM $MgCl_2$, 50 mM KCl, 10 mM Tris-HCI(pH 9.0), 0.1% Triton X-100, 1.5 unit Taq polymerase(promega)였다. 여섯 개의 primer가 Pleurotus속 8종의 균주에서 RAPD polymorphism을 보임을 알 수 있었으며, 이들의 염기배열은 PR2(GGG GGG AAG C), PR3(GCG GTT GAG G), PR4(CGC ACC GCA C), PR10(CAA TCG CCG T), PR11(CAG CAC CCA C), PR17(TAG GCG TAT CAG GAG GCC CT)이었다.
This study describes the effects of several components on PCR amplification used for RAPD. We used different concentrations of reaction components to obtaine discrete and reproducible PCR products from Pleurotus cornucopiae. The optimum concentrations of reaction components were found to be 80 ng of template DNA, 30 pmole of 10-mer primer, $200;{mu}M$ dNTP, 2mM $MgCl_2$, 50 mM KCl, 10 mM Tris-HCl(pH 9.0), 0.1% Triton X-100, 1.5 unit of Taq DNA polymerase (promega) in $50;{mu}l$ reaction volume. The optimum annealing temperature was $35^{circ}C$. These results proved to be valuable for characterization of Pleurotus spp.
