Arabidopsis mutants defective in exine pattern formation. Scanning electron micrographs of pollen grains (a-d), confocal images of pollen stained with 0.1% auramine O (e-h,l), and transmission electron micrographs of mature pollen sections (i-k, arrows indicate sporopollenin). Wild type Landsberg (a,e and i), cals5-3 (b,f, and j), cals5-4 (c, g, and k), cals5-5 (d and h), and cals5-3 /+ (l). Bars, 10 μm (a-h, l); 1 μm (i-k).
