Defence gene expression (A) and salicylic acid (SA) production (B) in the double mutant cad‐C/cad‐D (triangles) and wild‐type (squares) after inoculation with water (blue), Pseudomonas syringae pv. tomato (Pst) DC3000 (pink) and Pst DC3000/avrRpt2 (green). (A) The expression values of each gene were normalized using the expression level of β‐tubulin4 as an internal standard. The mean values and standard errors were calculated from two independent experiments. AU, arbitrary units. (B) For SA measurement, the mean values and standard errors were calculated from two independent experiments.
