Copper and iron are the limiting factors for growth of the yeast Saccharomyces cerevisiae in an alkaline environment.

Abstract excerpt

Exposure of the yeast Saccharomyces cerevisiae to an alkaline environment represents a stress situation that negatively affects growth and results in an adaptive transcriptional response. We screened a collection of 4825 haploid deletion mutants for their ability to grow at mild alkaline pH, and we identified 118 genes, involved in numerous cellular functions, whose absence results in reduced growth. The list...
