Initiation of appressorial germ tube differentiation and appressorial hooking: distinct morphological events regulated by cAMP signalling in Blumeria graminis f.sp hordei

Appressorial differentiation by conidia of the barley powdery mildew fungus, Blumeria graminis f.sp.hordei, is dependent on perception of multiple leaf-derived signals. Recently, we have demonstrated that cAMP signalling and PKA play an important, but complex, role during early B. graminis conidial...
