Expression levels of JA and SA signaling pathway-related genes in rice plants damaged by oral secretion collected from AB-treated or untreated larvae. Gene expression was analyzed 24 h after treatment. Different letters above bars indicate statistically significant differences between treatments (ANOVA, P < 0.05; followed by LSD test; OsHI-LOX, F(3,20) = 39.44, P < 0.001; OsAOS2, F(3,20) = 19.78, P < 0.001; OsPAL1, F(3,20) = 332, P < 0.001; OsPR-1a, F(3,20) = 85.85, P < 0.001; n = 6). CK, untreated rice plants; Water, rice stems wounded and applied with sterilized water; OS-AB, rice stems wounded and treated with oral secretion collected from larvae without AB; OS + AB, rice stems wounded and treated with oral secretion collected from larvae with AB
