FIGURE 1.

Kinetic analysis of jasmonate accumulation in wild-type (WT) and in jar1 mutant plants upon leaf wounding. Leaves were harvested at increasing times after wounding and extracted for jasmonate determination by UPLC-MS/MS. A, JA; B, JA-Ile; C, 12OH-JA; D, 12OH-JA-Ile. Data are mean ± S.E. from three biological samples. Asterisks indicate significant differences between mutant and WT at p < 0.01 (**) or p < 0.001 (***) (two-way ANOVA). Similar results were obtained in two independent experiments.
