Images of seedlings (4 DAS) from left to right (A, C): transgenic maize expressing green fluorescent protein (GFP), transgenic wheat expressing red fluorescent protein (RFP) and rapeseed wild-type grown on blotting paper and images of a rhizotron filled with soil containing three plants: maize expressing the GFP, wheat expressing the RFP and rapeseed WT (12 DAS).

Pictures were taken either with a conventional camera (Faget et al., 2009) (A, C) or with a modified camera allowing to capture the green and red fluorescence emission wave lengths. The images of GFP and RFP signals were than merged together (B, D).
