Stabilized ICL is peroxisome associated in pex4–1 pex22–1 and pex6 and cytosolic in pex5–10. Cotyledons from 4- and 8-day-old light-grown Arabidopsis seedlings were dually immunolabeled with rabbit α-ICL (magenta, left columns) and mouse α-catalase (green, center columns) antibodies and were visualized via fluorescence microscopy. Overlays of ICL and catalase images (white, right columns) show co-localizations. The icl-1 null mutant exhibits background fluorescence from the α-ICL antibody. Bar, 10 μm.
