Jasmonic acid (JA) promotes resistance to necrotrophic Cochliobolus heterostrophus. Lesion areas of (a) opr2‐1, lox10‐3, and lox10opr2 mutants and wild type (WT) and (b) JA‐deficient opr7opr8 mutant and WT. Plants were sprayed with 2 ml of mock or 100 μM MeJA per plant 1 h prior to inoculation with C. heterostrophus. Disease symptoms were scanned and lesion areas were measured using ImageJ software. The data are shown in the box and whisker plot and X indicates means (n = 36 lesions from six different plants of each genotype as biological replicates). Outliers are represented by dots. Different letters indicate statistically significant differences (Tukey's HSD test, p < 0.05). These experiments were repeated at least two times with similar results.
