Fig. 5From: Contribution of the non-effector members of the HrpL regulon, iaaL and matE, to the virulence of Pseudomonas syringae pv. tomato DC3000 in tomato plantsHost response to infection with P. syringae pv. tomato DC3000 and its ΔiaaL and ΔmatE mutant derivatives. a Images and b time course of blue fluorescence emission (F440) from tomato leaves infiltrated with either MgCl2 (control plants) or the indicated strains. c Images and d time course of green fluorescence emission (F520). Pictures show representative images of the fluorescence measurements carried out in control and bacteria-challenged tomato plants at 2, 4, 7 and 9 dpi. Three different experiments with four repetitions for every sample were performed. The color scale applied is shown for panels a and c. Averages for the whole inoculated area at each dpi assayed are displayed; error bars indicate standard error and significant differences are marked (*)Back to article page
