malfunction | a pdeHDELTA/pdeLDELTA mutant shows reduced conidiation, exhibits dramatically increased cAMP levels relative to the wild-type, and is completely defective in virulence | Pyricularia oryzae |
malfunction | loss of PdeH leads to increased accumulation of intracellular cAMP during vegetative and infectious growth. Furthermore, the pdeHD shows 2-3fold enhanced conidiation, precocious appressorial development, loss of surface dependency during pathogenesis, and highly reduced in planta growth and host colonization. A pdeHDELTA/pdeLDELTA mutant shows reduced conidiation, exhibits dramatically increased cAMP levels relative to the wild-type, and is completely defective in virulence | Pyricularia oryzae |
metabolism | cyclic AMP-dependent pathways mediate the communication between external stimuli and the intracellular signaling machinery, thereby influencing important aspects of cellular growth, morphogenesis and differentiation. Crucial to proper function and robustness of these signaling cascades is the strict regulation and maintenance of intracellular levels of cAMP through a fine balance between biosynthesis, by adenylate cyclases, and hydrolysis, by cAMP phosphodiesterases | Pyricularia oryzae |
physiological function | expendable PdeL function | Pyricularia oryzae |
physiological function | PDEH is necessary for proper aerial hyphal growth. PdeH-dependent biphasic regulation of cAMP levels during early and late stages of appressorial development. PdeH-mediated sustainance and dynamic regulation of cAMP signaling during Magnaporthe oryzae development is crucial for successful establishment and spread of the blast disease in rice. The PdeH activity is a key regulator of asexual and pathogenic development in Magnaporthe oryzae | Pyricularia oryzae |
