JA- but not SA-induced disease resistance against P. syringae is impaired in the ocp3-1 mutant. Two-week-old plants were treated by dipping with a solution of 50 μM MeJA (light grey), 50 μM SA (white) or MgSO4 as control treatment (black). After two days, plants were challenge inoculated as described in Figure 1b. Asterisks indicate significant difference from the control treatment (P < 0.05) using the Student's t test. The experiments were repeated a minimum of three times with similar results.
