Conidial germination and functional appressorium formation. (A) Conidial germination and appressorium formation. (B) Conidial germination rate (%) of P. oryzae strains at 4, 8, 12, 24 hpi. (C) Appressorium formation rate (%) of P. oryzae strains at 12 and 24 hpi. (D) Conidial germination, appressorium formation and penetration onion epidermis. (E) penetration rate (%) of P. oryzae appressorium at 24 and 36 hpi. Error bars represent mean ± SD (n=3). Asterisks indicate significant differences from AM16 strain according to Student’s t-test (**p < 0.01). Scale bars, 10 µm.
