PexRD2 Suppresses the Cell Death Associated with the Avr4/Cf4 HR.

Coexpression of ^GFPPexRD2 with the both the C. fulvum effector Avr4 and tomato resistance protein Cf4 in N. benthamiana reduces the percentage of infiltration sites with >50% confluent cell death at 3 to 7 d postagroinfiltration (dpi) compared with the GFP control. Results are the mean ± se of three independent experiments, each using at least four plants. Asterisks indicate a value significantly different from the GFP control at the same time point (P < 0.01) as determined by one-way ANOVA; all other values were not significantly different (P > 0.05). Images indicate representative infiltration sites at 7 dpi.
