Proper regulation of cyclic AMP-dependent protein kinase is required for growth, conidiation, and appressorium function in the anthracnose fungus Colletotrichum lagenarium.

Abstract excerpt

Colletotrichum lagenarium, the casual agent of anthracnose of cucumber, forms specialized infection structures, called appressoria, during infection. To evaluate the role of cAMP signaling in C. lagenarium, we isolated and functionally characterized the regulatory subunit gene of the cAMP-dependent protein kinase (PKA). The RPK1 gene encoding the PKA regulatory subunit was isolated from C. lagenarium by...
