Peroxisomal targeting. A–C, YFP-MFP2 in cotyledon epidermis, hypocotyl epidermis, ansd root tip tissue. D–F, CFP-MFP2 in hypocotyl, leaf mesophyll, and root epidermis. G–I, CFP-Pex5 in cotyledon epidermis, leaf mesophyll, and root axis tissue. YFP signal is indicated in green, CFP signal is indicated in blue, and plastid autofluorescence is in red. To visualize cell outlines, roots were stained with propidium iodide indicated in red. All images are projections of several confocal sections. Bars represent 10 μm.
