Electrolyte leakage from wild‐type N. benthamiana leaf discs from plants with MgCl₂ control, TRV‐GFP or TRV‐NbXEGIP1 treatments at 66 h post‐inoculation with P. syringae pv. tabaci.

Treatment*	Relative conductivity†
MgCl2 control	0.41 a
TRV‐GFP control	0.44 a
TRV‐NbXEGIP1	0.54 b

^* N. benthamiana plants were infiltrated with A. tumefaciens containing TRV1 and TRV2 with a GFP insert (TRV‐GFP control), or containing TRV1 and TRV2 with a fragment of NbXEGIP1 (TRV‐NbXEGIP1) or with 10 mm MgCl₂ without any A. tumefaciens (MgCl₂ control).

^† At 15–18 days after A. tumefaciens infiltration to induce silencing, the two youngest fully developed leaves of each plant were infiltrated with P. syringae pv. tabaci. Relative conductivity values were means pooled from three separate experiments with a total of 15 replications. Means in the same column followed by the same letter are not significantly different according to the anova Fisher multiple comparisons test at P < 0.05.
