A Rapid Method for Preparation of Fungal Chromosome DNA / 微生物学通报

The article introduce a rapid method for preparation of fungal chromosome DNA In this method the quartz sand is used to break the fungal cell wall and the chromosome DNA is harvested rapidly in 1～2 h The method is applied successfully by the author to four kinds of fungi Neurospora crassa , Aspergillus oryzae , Morchella esculcnta , Saccharomyces cervisae All the chromosome DNA extracted has the fragment size lager than 20 kb and can be used directly for either digestion with restriction endoenzyme or PCR
