We have used the ability to induce high levels of Ty transposition to develop a method for transposon mutagenesis in Saccharomyces cerevisiae. To facilitate genetic and molecular analysis, we have constructed GAL1-promoted TyH3 or Ty917 elements that contain unique cloning sites, and marked these elements with selectable genes. These genes include the yeast HIS3 gene, and the plasmid PiAN7 containing the Tn903 NEO gene. The marked Ty elements retain their ability to transpose, to mutate the LYS2, LYS5, or STE2 genes, and to activate the promoterless his3 delta 4 target gene. Ty elements containing selectable genes are also useful in strain construction, in chromosomal mapping, and in gene cloning strategies.
我们利用诱导高水平Ty转座的能力,开发了一种在酿酒酵母中进行转座子诱变的方法。为便于进行遗传和分子分析,我们构建了含有独特克隆位点的GAL1启动的TyH3或Ty917元件,并用选择基因对这些元件进行标记。这些基因包括酵母HIS3基因,以及含有Tn903 NEO基因的质粒PiAN7。标记后的Ty元件保留了其转座能力、使LYS2、LYS5或STE2基因突变的能力,以及激活无启动子his3 delta 4靶基因的能力。含有选择基因的Ty元件在菌株构建、染色体定位和基因克隆策略中也很有用。
