Basal expression of DEX:His:avrE in transgenic Arabidopsis complemented the growth of the ∆CEL mutant. A, Western-blot analysis of His:AvrE proteins in transgenic Arabidopsis plants 6 h after 30 µm DEX treatment. A polyclonal AvrE antibody was used to detect AvrE. The red arrow indicates the predicted size of AvrE. B, Representative images of 4-week-old Col-0 and transgenic DEX:His:avrE plants. C, Basal expression of DEX:His:avrE in transgenic Arabidopsis lines L1 and L6 is sufficient to substantially enhance the growth of the ∆CEL mutant. DC3000, ∆CEL, and hrcC were hand infiltrated at 1 × 10⁶ colony-forming units (cfu) mL⁻¹. Bacterial numbers were counted 3 d after infiltration. Asterisks indicate significant differences between Col-0 and L1 or L6: **, P < 0.01; and *, P < 0.05.
