Cell death phenotype and bacterial growth in DEX:CaXEGIP1 transgenic Arabidopsis plants infiltrated with Pst DC3000. A and B, Disease symptoms developed on the leaves of DEX:CaXEGIP1 transgenic Arabidopsis 8 d after inoculation with virulent Pst DC3000 (A) and avirulent Pst DC3000 (avrRpm1) (B; 10⁷ cfu mL⁻¹). Arabidopsis plants were inoculated with Pst DC3000 24 h after mock treatment or 30 μm DEX treatment. C, Bacterial growth in DEX:CaXEGIP1 transgenic Arabidopsis leaves 0 and 3 d after inoculation with virulent Pst DC3000 and avirulent Pst DC3000 (avrRpm1) strains (10⁵ cfu mL⁻¹). The data represent means ± sd from three independent experiments. [See online article for color version of this figure.]
