Figure 1

Leaves of Col-0, pad2 - 1 and vtc2 - 1 after the exposure to different light regimes for 14 d. Representative images of leaves from Arabidopsis thaliana Col-0 (first row), and the mutants pad2-1 (second row) and vtc2-1 (third row) grown under different light regimes for 14 d. First signs of light induced changes can be found on leaves of Col-0 grown at 300 μmol m-2 s-1 which developed dark blue stained spots on the leaf surface (circles) and on the main vascular vein. First symptoms of dark blue stained areas on the leaves of pad2-1 and vtc2-1 could be observed when mutants were grown under 700 μmol m-2 s-1. On leaves of the wildtype necrotic lesions (arrow) could be observed on the leaf edges at this light intensity. When leaves were exposed to 1,500 μmol m-2 s-1 large blue stained areas, advanced browning and necrotic lesions at the edge of the leaves (arrows) could be observed on Arabidopsis Col-0, the pad2-1 and the vtc2-1 mutant.
