The effect of E-2-hexenal is partially dependent on coronatine. Bacterial populations of the cor mutant (DC3682) in inoculated Ler and hpl1 leaves at 72 hpi. Plants were pre-treated 24 h with 3 μM E-2-hexenal or methanol. Values are the mean of 24 sets of two leaf disks from 20 plants. Error bars represent standard error. All pre-treatments with E-2-hexenal were significantly different from the control treatment (P < 0.05, according to Student’s t-test analysis). The data presented are from a representative experiment that was repeated three times with similar results.
