title: [A method for preparation of genomic DNA from Grifola frondosa and construction of a genomic library].
abstract: Grifola frondosa, is a valuable medicinal fungus. High quality total genomic DNA is difficult to prepare due to its high polysaccharide content. A method for the preparation of Grifola frondosa total genomic DNA and construction of Grifola frondosa, genomic library is described. Genomic DNA prepared by this method is digested by Sau3A I restriction enzyme. Constructed genomic library give a titer of 2 x 10(5) transformants/50mg , with a average insert size of 14kb. This has paved way for the cloning of other Grifola frondosa genes and molecular biology studies.
