摘 要: 灰樹花是一種珍貴的藥用真菌,因為多糖含量較高,較難獲得高質(zhì)量的總DNA,本文提出了一種制備高質(zhì)量灰樹花總DNA及構建灰樹花基因組文庫的方法。該方法制備的灰樹花總DNA,經(jīng)Sau3AI酶切后,用于構建基因組文庫,可得到2×105個轉化子/50mg,平均插入片段為14kb。本研究為下一步克隆灰樹花中的基因以及進行其他分子生物學研究奠定了基礎。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 2×105 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.
