Appressorium formation and infection assays with the pic1 mutant. (A) Conidia of the wild-type 70-15, pic1 mutant strains GA15 and GA22, and complemented transformant MC93 were incubated on glass coverslips (upper panels) and onion epidermal cells (lower panel) for 24 h. Bar = 10 μm. (B) Rice leaves sprayed with conidia from 70-15, pic1 mutants GA15 and GA22, and complemented strain MC93.
