Figure 3. Suppression of gene silencing.
(a) N. benthamiana leaf observed under UV light, agroinfiltrated with strains bearing 35S-gfp; 35S-gfp + 35S-ds gfp or 35S-gfp + 35S-ds gfp + 35S-HC-Pro constructs.
(b) Transgenic GFP leaf (line 16C) agroinfiltrated with 35S-ds gfp or 35S-ds gfp + 35S-HC-Pro.
(c) N. tabacum silenced for endogenous pds showing the photobleaching phenotype (left panel) and the same plant infected with PVY after 2 weeks (right panel). The arrow points at the initially infected leaf.
