摘  要:
[Objective]To optimize ISSR-PCR reaction system and reaction condition of Portulaca oleracea L.[Method]Taking P. oleracea L. as the research object,using improved CTAB method to extract total DNA of P. oleracea L.,the ISSR-PCR primers were screened,at the same time ISSR-PCR reaction system and reaction condition were optimized to test ISSR-PCR products by electrophoresis. [Result]Eight primers were suitable for ISSR-PCRof P. oleracea L.. The optimal reaction system was that total reaction system 25. 0 μL,including 12. 5 μL 2 × Taq Platinum PCR Master Mix,2. 0 μL 10 μmol/L primers,1. 0 μL 40 mg/L DNA templates,9. 5 μL dd H_2O. The optimal reaction condition was that pre-degeneration at 94 ℃ for 360 s,going to 30 cycles: degeneration at 94 ℃ for 60 s,annealing at 54 ℃ for 60 s,extension at 72 ℃ for 90 s,then extension at 72 ℃ for 300 s after 30 cycles.[Conclusion]The optimizing ISSR-PCR reaction system and reaction condition of P. oleracea L. were established to provide basis for further study P. oleracea L..
