In this work was used an experimental system based on an <em>S. cerevisiae</em> yeast mutant with a lack of the glutathione reductase enzyme and allyl alcohol as a precursor of acrolein inside the cell to determine the cellular processes influencing glutathione homeostasis.

The regulatory mechanisms underlying this switch are unknown. Here, we demonstrate that a differential heat stress response is ubiquitous in <em>Z. tritici</em> populations around the world. We used QTL mapping to identify a single locus associated with the temperature-dependent morphogenesis and we found two genes, the transcription factor <em>ZtMsr1</em> and the protein phosphatase <em>ZtYvh1</em>, regulating this mechanism. We find that <em>ZtMsr1</em> regulates repression of hyphal growth and induces chlamydospore formation whereas <em>ZtYvh1</em> is required for hyphal growth. We next showed that chlamydospore formation is a response to the intracellular osmotic stress generated by the heat stress. This intracellular stress stimulates the cell wall integrity (CWI) and high-osmolarity glycerol (HOG) MAPK pathways resulting in hyphal growth. If cell wall integrity is compromised, however, <em>ZtMsr1</em> represses the hyphal development program and may induce the chlamydospore-inducing genes as a stress-response survival strategy.
