Col-0 (a, d, g), CCA1ox (b, e, h) and cca1lhy (c, f, i) seedlings were sprayed with 1 mM SA or mock (water) at subjective dawn versus dusk. Seedlings were sampled 6 h after treatment and PR1transcript levels were measured. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, unpaired t test. Error bars indicate mean ± SEM (n = 4). The data shown here are from three independent experiments: experiment 1 (a–c); experiment 2 (d–f); experiment 3 (g–i). We present all the results to demonstrate consistency between the independent repeats.
