Model for the regulatory function of PKA in the cAMP pathway. Adenylate cyclase ACY impacts cAMP dependent function of PKA. The regulation of plant cell wall degrading enzymes by PKA is in parts mediated via phosphorylation of the carbon catabolite repressor CRE1 and the photoreceptor complex of BLR1 and BLR2. Function of the photoreceptor ENV1 on the BLR-complex overlaps with PKA regulation regarding enzyme production. The regulatory effect of ENV1 in part shows a cAMP level dependent output. PKA further positively impacts sexual development as well as production of secondary metabolites (for details see “Background”)
