Abstract

Abstract A novel homolog of laeA, a global regulatory gene in filamentous fungi, was identified from Pyricularia oryzae. A deletion mutant of the homolog (PoLAE2) exhibited lowered intracellular cAMP levels, and decreased appressorium formation on non-host surface; the decrease was recovered using exogenous cAMP and IBMX, indicating that PoLAE2 deletion affected the cAMP signaling pathway.
