| 摘 要： | 利用大肠杆菌一酵母穿梭质粒pGBT9构建了一个真菌启动子捕获载体pCBT14，用这个捕获载体构建了含顶头孢霉的0．5～2．0kb片段的染色体DNA文库，并从中筛选到顶头孢霉的24个DNA片段，这些片段能够在啤酒酵母中启动Trp1基因的表达。

| Abstract: | A promoter-trap vector pGBT14 for selecting promoters of fungus gene was constructed with E. coli-yeast shuttling plasmid pGBT9. Using this vector, a0. 5-2. 0kb chromosomal DNA library of Cepholosporium acremonium was constructed, and twenty four DNA fragments with promoter function in Saccharomyces oerevisiae Y153 were selected from this DNA library. And the promoter function of these DNA fragments was analyzed. |
