JA-Ile is not the only active oxylipin signal eliciting antiherbivore defenses. A, Mean (±se) JA-Ile/Leu and JA concentrations of four replicate wild-type, aslox3, and irjar4/6 (irjar4-2/6-2) plants 1 h after OS treatment. B, Mean (±se) transcript levels of TPI and nicotine concentrations in four replicated wild-type, aslox3, or irjar4/6 (irjar4-2/6-2) plants 10 h (for TPI) or 72 h (for nicotine) after OS elicitation. C, Mean (±se) mass of 18 replicated M. sexta larvae feeding on wild-type, aslox3, and irjar4/6 plants (irjar4-2/6-2). Rosette-stage plants were wounded and treated with water (wounding + water) or 0.25 μmol JA-Ile (wounding + JA-Ile). One day later, one freshly hatched larva was placed on treated leaves of each treated plant. Asterisks represent significant differences between members of a pair (Student's t test; *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001).
