  1. Simplified lignin biosynthetic pathway.
  2. Quantification of lignin content in palQ leaves after the indicated treatments and pathogen infection. Data are shown as means ± SD (n = 4; 3–9 leaves each).
  3. Measurements of Pst DC3000 (AvrRpm1) growth. Data are shown as means ± SD (n = 3).
  4. Cell death phenotypes of leaves inoculated with Pst DC3000 (AvrRpm1).
  5. Quantification of leaves (n ≥ 30) with spreading cell death as in (D).
  6. Quantification of total and free SA in Col‐0 and palQ leaves after the indicated treatments and pathogen infection. Data are shown as means ± SD (n = 5; 6 leaves each).
Data information: Six‐week‐old leaves were inoculated with Pst DC3000 (AvrRpm1) at 105 cfu/ml for growth assays and at 108 cfu/ml for other experiments. Different letters indicate significant differences (Tukey's HSD test; P < 0.05). Experiments were repeated three times with similar results. M, mock; PA, piperonylic acid; CA, coniferyl alcohol; dpi, days post‐inoculation.
