FIGURE 4.

Selective degradation of GFP driven by NSlmb-VHHGFP4 fusion proteins in planta measured by competitive ELISA for quantification of GFP. Five parallels of each native plant extract dilution as well as five parallels of each eGFP standard dilution were incubated and measured on the same ELISA plate. GFP plant extracts (N. tabacum GFP) were also measured on each plate. Resulting arithmetic means were presented including standard deviations given as bars. (A,B) Transgenic lines expressing NSlmb-VHHGFP4 and GFP. (C) Transgenic lines expressing NSnoFbox-VHHGFP4 and GFP.
