Magnaporthe oryzae encodes eight putative RhoGAP proteins.
MoRga1 regulates conidial morphology and appressorial formation.
MoLrg1 is required for conidiogenesis, vegetative growth and pathogenicity.
Both MoRga1 and MoLrg1 interact with MoRac1 and MoCdc42.
LIM domain, RhoGAP domain and Arginine 1032 are all essential for MoRga1 function.
