FIGURE 1.

Bacterial growth in tomatoes expressing Roq1. Xanthomonas perforans 4B (Xp), Xanthomonas euvesicatoria 85-10 (Xe), and Pseudomonas syringae DC3000 (Ps) were infiltrated into leaf tissue of wild-type tomato and tomato expressing Roq1 at a low inoculum (OD₆₀₀ = 0.0001 for Xe and Xp; OD₆₀₀ = 0.00005 for Ps). Bacterial abundance was quantified by homogenizing leaf punches and counting colony forming units (CFU) per square centimeter of leaf tissue at 6 days post infiltration for Xe and Xp; 3 days post infiltration for Ps. Error bars indicate standard deviation from three biological replicates. *p < 0.05, **p < 0.01 by Student’s t-test.
