The expression of ALEX1 activates JA pathway and enhances resistance in rice. (a and b) Relative expression levels of genes function in JA biosynthesis (a) and signalling (b) of WT and ALEX1‐expressing lines. Actin 2 was used as an endogenous control in quantitative real‐time PCR. The data are expressed as the mean ± SD of three replicates. Asterisks indicate statistically significant differences compared with wild type by Student's t test (**P < 0.01; ***P < 0.001). (c) A working model of the pathogen‐induced ALEX1 expression in activating JA pathway and rice defence.
