"Here, we describe a genome-wide screen for mutants that present altered tolerance to hygromycin B, spermine and tetramethylammonium. Two hundred twenty six mutant strains displayed altered tolerance to all three drugs (202 hypersensitive and 24 hypertolerant) and more than 50% presented a strong or moderate growth defect at limiting potassium (1 mM). Functional groups such as protein kinases and phosphatases, intracellular trafficking, transcription or cell cycle and DNA processing were enriched. Essentially, our screen has identified a substantial number of genes which were not previously described to play a direct or indirect role in potassium homeostasis. A subset of 27 representative mutants were selected and subjected to diverse biochemical tests that, in some cases, allow us to postulate the basis for the observed phenotypes" . "Herrera, R." . .
