Abstract Saccharomyces cerevisiae was used to uncover the mechanisms underlying tolerance and toxicity of the agricultural fungicide mancozeb, linked to cancer and Parkinson's disease development. Chemogenomics screening of a yeast deletion mutant collection revealed 286 genes that provide protection against mancozeb toxicity. The most significant Gene Ontology (GO) terms enriched in this dataset are associated to transcriptional machinery, vacuolar organization and biogenesis, intracellular trafficking, and cellular pH regulation. Clustering based on physical and genetic interactions further highlighted the role of oxidative stress response, protein degradation and carbohydrate/energy metabolism in mancozeb stress tolerance. Mancozeb was found to act in yeast as a thiol-reactive compound, but not as a free radical or reative oxygen species (ROS) inducer, leading to massive oxidation of protein cysteins, consistent with the requirement of genes involved in glutathione biosynthesis and reduction and in protein degradation to provide mancozeb resistance. The identification of Botrytis cinerea homologues of yeast mancozeb tolerance determinants is expected to guide studies on mancozeb mechanisms of action and tolerance in phytopathogenic fungi. The generated networks of protein-protein associations of yeast mancozeb tolerance determinants and their human orthologues share a high degree of similarity. This toxicogenomics analysis may, thus, increase the understanding of mancozeb toxicity and adaptation mechanisms in humans.
