Abstract


A novel method, which is rapid, reliable and quantitative, is presented for measuring the toxic effects on yeast cells of high dosage of any given gene. It is based on the possibility of monitoring the presence in cells of a plasmid carrying the ADE2 gene from Saccharomyces cerevisiae by direct observation of colonies, the construction of this particular plasmid being easily made by marked homologous recombination in yeast. Four yeast regulatory genes tested were found to result in various degrees of toxicity at high dosage. Possible implications of the measurement of gene toxicity for eukaryotic cell regulatory mechanisms and for the use of novel general approaches to gene selection, such as the gene-gene interference method, are discussed.
