Fig. 6. Accumulation of oryzalactone and phytocassane G in response to rice blast infection and the antifungal activities of these compounds against rice blast. (A) Accumulation of oryzalactone in 'Jaguary' leaves in response to rice blast infection. (B) Accumulation of phytocassane G in 'Basilanon' leaves in response to rice blast infection.Amounts of 1 and 2 were determined 72 h after the start of treatment. n.d.: not detected. Values are means ± SD of three biological replicates. Asterisks indicate significant differences (*p <0.05, **p <0.01; Dunnett's test). (C) Effect of compounds on the germination of P. oryzae 12 h after incubation. (D) Effect of compounds on conidial germ tube elongation, which was measured 12 h after treatment.Values and error bars are means ± SD (n = 3). Different letters indicate significant differences (p <0.05; Tukey–Kramer method).
