Caption
Synchrotron X-ray Fluorescence Spectrometry images of a normal leaf (top row) and a leaf from the ilr3-4 mutant which shows bleaching (bottom row). From left to right, the images show the full leaf followed by the distribution of potassium (blue), calcium (red), and iron (green). Bleaching in ilr3-4 leaves is accompanied by redistribution of ions, with a strong depletion in potassium but enrichment of calcium in bleached sectors compared to surrounding healthy tissue.
