Distribution of Mitochondria, Peroxisomes, and Nuclei in Wild-Type and chup1 Cells.

(A) to (D) Arabidopsis palisade mesophyll cells transiently expressing mitochondria-targeted GFP. Confocal microscopic images of the sections near the top ([A] and [C]) and the bottom ([B] and [D]) of wild-type and chup1-2 cells, respectively. The green and red signals show fluorescence from GFP and autofluorescence from chloroplasts, respectively. Bar = 10 μm.

(E) to (H) Arabidopsis palisade mesophyll cells transiently expressing peroxisome-targeted GFP. Confocal microscopic images of the sections near the top ([E] and [G]) and the bottom ([F] and [H]) of wild-type and chup1-2 cells, respectively. Fluorescent colors are the same as in (A) to (D). Bar = 10 μm.

(A) to (H) represent projections of seven optical 1.0-μm sections.

(I) to (L) Positions of nuclei in Arabidopsis leaves. Cross-sections of wild-type and chup1-2 leaves were stained with 4′,6-diamidino-2-phenylindole to visualize nuclei ([I] and [K], respectively), and the same cross-sections are shown for the transmission images ([J] and [L], respectively). Bar = 30 μm.
