Elements of a single MAP kinase cascade in Saccharomyces cerevisiae mediate two developmental programs in the same cell type: mating and invasive growth.

Abstract excerpt

Diploid Saccharomyces cerevisiae strains starved for nitrogen undergo a developmental transition from a colonial form of growth to a filamentous pseudohyphal form. This dimorphism requires a polar budding pattern and elements of the MAP kinase signal transduction pathway essential for mating pheromone response in haploids. We report here that haploid strains exhibit an invasive growth behavior with many...
