cAMP-pKA signaling regulates multiple steps of fungal infection cooperatively with Cmk1 MAP kinase in Colletotrichum lagenarium.

Abstract

In Colletotrichum lagenarium, RPK1 encoding the regulatory subunit of PKA is required for pathogenicity. From the rpkl mutant that forms small colonies, we isolated three growth-suppressor mutants. All rpk1-suppressor mutants are nonpathogenic and contain amino acid changes in the PKA catalytic subunit Cpkl. To assess the roles of cyclic AMP (cAMP… (More)
