Screening of cotransformed hairy roots expressing the DsRed marker gene in composite tomato plants. Roots of in vitro composite plantlet (a, b) and composite plants harvested after 45 days growing in a pot (c–e) were visualized with a stereomicroscope under bright light (a, c) and under green fluorescence (b, d) for selection of cotransformed hairy roots. Composite plant exposed to a green fluorescent lamp and visualized through a red–orange photography filter (e). Similar results were obtained independently of the binary vector tested: pUBIcGFP-DR, pK7GWIWG2_II-RedRoot or pBGWFS7::pAtUbq10::DsRed
