Reduction of ORA59 expression influences E-2-hexenal effect on bacterial growth. (A) Bacterial populations of DC3000 in inoculated myc2 (jin1-7) and Col-0 leaves 72 hpi. Plants were pre-treated 24 h with 3 μM E-2-hexenal or methanol. (B) Bacterial populations of DC3000 in inoculated RNAi-ORA59 and 35S:GUS plants at 72 hpi. Plants were pre-treated with 3 μM E-2-hexenal or methanol for 24 h. 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), except for RNAi-ORA59. The data presented are from a representative experiment that was repeated three times with similar results.
