Figure 2. Systemic silencing progression.
(a) Transgenic plants expressing GFP (line 16C)
observed under UV light.
(b) Transgenic leaves of line 16C
agroinfiltrated with 35S-ds gfp after 1 week. The black dashed
line marks the agroinfiltrated zone.
(c) and (d) GFP plants agroinfiltrated with 35S-ds
gfp after 2 and 3 weeks respectively, the GFP signal is reduced
while the gene silencing signal is spread.
(e) Non transgenic
plant under the UV light.
