Overexpression of CmKFB under the control of the Cauliflower mosaic virus 35S promoter in stable transformed tomato plants. A, Visual comparison of control and T0 fruit peels. B, Microscopic view of control and T0 cuticles. C, Microscopic view of control and T0 fruit cut under UV light after DPBA staining (arrow marks the cuticle upper layer that did not emit any fluorescence). D, Leaves of T1 segregants of the first transgenic plant and ‘MP-1’ control grown under cold stress conditions: upper indicates visible light, and lower indicates GFP fluorescence.
