Expression patterns of plant defense-response genes. EDS1, PAD4, PAL, and ICS1 are the SA synthesis-related genes. NPR1 is a key regulator of SA-dependent systemic acquired resistance. LOX and AOS2 are the JA synthesis-related genes. PR1b is pathogen-related gene 1 in rice. EIN2 is the ethylene signaling pathway receptor gene. Rice Actin1 was used as reference control. Expression of genes was quantified relative to the value obtained from 0-h susceptible samples. Solid bars, the wild-type rice; open bars, the resistant homozygous Bph14-transgenic rice (Ra4–20). In all panels, the mean is based on the average of three biological repeats calculated. *, P < 0.05; **, P < 0.01. One-way ANOVA was used to generate the P values.
