| Outline of Final Research Achievements |
This study aimed to elucidate the molecular mechanism of survival strategy of methylotrophic yeasts which can survive and proliferate on growing plant leaves where cells are exposed to harsh environmental changes and stresses. Physiological role of stress granule (SG) formation and methanol-sensing mechanism in methylotrophic yeasts were investigated. We revealed that sequestration of activated Hog1 proteins in SGs is responsible for downregulation of Hog1 activity under high-temperature stress and that Wsc family proteins function in both the high temperature stress response and in methanol-sensing machinery.
