[Method] Boiling water DNA extraction method was improved, DNA extraction liquid was heated by PCR instrument and the extraction process was finished rapidly. [ Resuit] The quality of DNA obtained through mass and rapid extraction of fungal genomic DNA could meet the requirement of RAPD amplification analysis. The clear bands were amplified from 22 tested strains, the number of clear bands were different in the range of 2 -6 and the size of band were mainly concentrated in 450 -800 bp. The DNA extracted by this method also could completely meet the requirement of SCAR amplification. The amplified specific DNA bands used to mark the strain F263 were very clear. [Conclusion] This research provided relatively perfect method for mass and rapid extraction of fungal clenomic DNA.展开更多
