CCYV GFP expression in the systemic leaves of cucumber at 25 dpi. a From left to right: GFP expression in the leaf vein, GFP expression in a single cell beside the leaf vein, and GFP expression in the surrounding cells. Bars represent 200 μm. b Counting expression spots of the different constructs on systemic leaves. We selected 10 different visual fields for counting. Dark grey bars indicates the single fluorescent cells and light grey bars indicates the multiple cells showing fluorescence. Sgc, cgc, cgs represents the three different strategies used for GFP expression. * indicates significant difference with P value<0.05
