Coexpression of GFP and DsRED in N. benthamiana leaves by using viral vectors (6 dpi). Leaf sectors infected with a mixture of two TMV constructs expressing GFP or DsRED (A) or coinfiltrated with a PVX vector expressing GFP and a TMV vector expressing DsRED (B) are viewed under the UV light of a hand-held lamp. Protoplasts prepared from leaf areas coinfiltrated with TMV constructs (C and D) or PVX and TMV constructs (E and F) are viewed under blue (C and E) or red (D and F) light.
