摘 要: 灰樹(shù)花是一種珍貴的藥用真菌,因?yàn)槎嗵呛枯^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(shù)花總DNA及構(gòu)建灰樹(shù)花基因組文庫(kù)的方法。該方法制備的灰樹(shù)花總DNA,經(jīng)Sau3AI酶切后,用于構(gòu)建基因組文庫(kù),可得到2×105個(gè)轉(zhuǎn)化子/50mg,平均插入片段為14kb。本研究為下一步克隆灰樹(shù)花中的基因以及進(jìn)行其他分子生物學(xué)研究奠定了基礎(chǔ)。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.
