ET and JA repress disease resistance through SA and PAD4. Growth is shown for Pst DC3000 in the wild-type Col-0 and single and combined mutants of dde2, ein2, sid2, and pad4. The bacterial growth was measured at 3, 3, and 4 dpi for 22°C (A), 28°C (B), and 16°C (C), respectively. Values represent means ± sd (n = 3). Letters indicate statistically significant differences among different genotypes determined by ANOVA (P < 0.05). Similar results were obtained in three independent experiments, and shown is the result from one experiment with three biological repeats. cfu, colony-forming units; FW, fresh weight.
