FIG. 6.

Growth of DC3000ΔavrPtoΔavrPtoB expressing AvrPtoB or the AvrPtoB homologs. (A) RG-PtoS. (B) RG-prf3. (C) RG-pto11. The bacterial strains were vacuum infiltrated into leaves of Rio-Grande tomato lines, and the bacterial populations were measured 0, 2, and 4 days after inoculation. The error bars indicate the standard deviations for three 1-cm-diameter leaf disks. Data analysis was performed using Duncan's multiple-range test. Means with the same letter above the bars are not different at a significance level of 5%. ev, empty vector pCPP45. The experiments were performed twice, and similar results were obtained.
