MAP kinase and cAMP signaling pathways modulate the pH-induced yeast-to-mycelium dimorphic transition in the corn smut fungus Ustilago maydis.

Abstract excerpt

Acid pH induces the yeast-to-mycelium transition in haploid cells of Ustilago maydis. We tested two signal transduction pathways known to be involved in dimorphism for roles in acid-induced filamentation. In wild-type cells intracellular cAMP levels were reduced under acid growth. A mutant defective in the regulatory subunit of PKA, ubc1, failed to respond to acid induction on solid medium, but in liquid medium...
