Mutant ocp3-1 is not JA-insensitive. Effect of JA on Col-0 and ocp3-1 plants. Plants were grown in MS plates supplemented with indicated MeJA concentrations during 10 days. Root growth inhibition was represented as the difference to the control (0 μM MeJA) treatment. (a) Root growth inhibition. Bars represent the JA-induced rooth-growth inhibition in Col-0 (black bars) and ocp3-1 plants (white bars). (b) Anthocyanin accumulation. Lines represent the anthocyanin accumulation in the same experiment. Anthocyanin quantification was performed by a spectrophotometric method. Error bars represent standard deviation (n = 5 plates). The experiments were repeated three times with similar results.
