Chloroplast structure in the <i>mda1</i> mutants.

<p>(A, D, G) Confocal micrographs showing chlorophyll autofluorescence in mesophyll cells of Col-0 (A), <i>mda1-1</i> (D) and <i>mda1-2</i> (G) third-node leaves. (B, C, E, F, H and I). Transmission electron micrographs of chloroplasts of a Col-0 (B), <i>mda1-1</i> (E) and <i>mda1-2</i> (H) mesophyll cell. Close-up views of Col-0 (C), <i>mda1-1</i> (F) and <i>mda1-2</i> (I) chloroplasts. Photographs were taken 21 days after stratification (das). Bars = 20 µm (A, D, G), 5 µm (B, E, H) and 2 µm (C, F, I).
