The cAMP-dependent protein kinase catalytic subunit is required for appressorium formation and pathogenesis by the rice blast pathogen Magnaporthe grisea.

Abstract excerpt

Magnaporthe grisea, the causal agent of rice blast disease, differentiates a specialized infection cell, an appressorium, that is required for infection of its host. Previously, cAMP was implicated in the endogenous signaling pathway leading to appressorium formation. To obtain direct evidence for the role of cAMP in appressorium formation, the gene encoding the catalytic subunit of the cAMP-dependent protein...
