Abstract

We isolated and characterized BMK1, a gene encoding a mitogen-activated protein kinase (MAPK), from the rice leaf spot pathogen Bipolaris oryzae. The deduced amino acid sequence showed significant homology with Fus3/Kss1 MAPK homologues from other phytopathogenic fungi. The BMK1 disruptants showed impaired hyphal growth, no conidial production, and loss of virulence against rice leaves, indicating that the BMK1 is essential for conidiation and pathogenicity in B. oryzae.
