| Research Abstract |
To identify gene functions involved in repair mechanism for oxidative damage in budding yeast Saccharomyces cerevisiae,we conducted genome-wide phenotype analyses using the complete collection of mutant strains deleted for each of all non-essential genes of budding yeast and the Decreased Abundance by mRNA Perturbation (DAmP) Yeast Library. The results suggest that genes related to RNA polymerases and the Ubiquitin-Proteasome system, as well as vacuolar acidification that were identified to be critical for tolerance to oxidative stress in our previous study, play important roles in tolerance to oxidative stress. We constructed a systematic library for comprehensive overexpression screens in S. cerevisiae using the systematic collection of yeast genome in a high-copy vector. Using this overexpression library, we screened strains that showed resistance or sensitivity to oxidative stress.
