Root response to OPDA. Relative root lengths (treated versus untreated) of 7-d seedlings grown on one-half-strength LS medium supplemented with 250 nm OPDA or 10 µm MeJA are shown. Data represent means ± se of three independent experiments. For each experiment, n = 50. Student’s t test. *, Statistically significant difference of P < 0.01 from the wild type (Col-0, Col-3, or Ws-4); **, statistically significant difference of P < 0.001 from the wild type (Col-0, Col-3, or Ws-4); #, mutants in Ws-4 background; §, mutants in Col-3 background.
