Effects of brown planthopper (BPH) infestation on the brassinosteroid (BR) pathway in rice. (A) Quantitative reverse-transcription PCR (qRT-PCR) analysis of BR-related genes (OsBRI1, OsBZR1, D11, SLG, and D2) in rice. Leaf sheaths of 2-week-old Zhonghua 11 plants at 0, 6, 12, and 24 h after infestation with BPH were used for analyses, with Actin as the internal reference gene. Data are means (±SD), n=3. The expression level at 0 h was set as 1.0. Significant differences compared with the expression level at 0 h were determined by one-way ANOVA with post hoc contrasts by Tukey test: *P<0.05. (B) Levels of castasterone (CS) and 6-deoxocastasterone (6-deoxoCS) in rice stems of non-infested and BPH-infested plants. Data are means (±SD), n=3. Significant differences were determined by one-way ANOVA: *P<0.05.
