3. Suppression of gene silencing.
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.
Transgenic GFP leaf (line 16C)
agroinfiltrated with 35S-ds gfp or 35S-ds gfp + 35S-HC-Pro.
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.
