Binding of the 30-amino acids necrosis inducing region to the plant cell surface. Tobacco protoplast were incubated with the elicitor region fused to either end of GFP (GFP-EliX, EliX-GFP), or with GFP alone as a control, and then observed with a fluorescence microscope under visible light or under the appropriate UV light to reveal either chlorophyll or GFP.
