Morphological analysis of pollen from p5cs1 p5cs2/P5CS2 and wild type. Acetic orcein stain of pollen from wild type (A and C) and p5cs1 p5cs2/P5CS2 plants (B and D) at two different magnifications show the presence in the latter pollen of small and shriveled pollen grains (arrows) alongside normal-looking grains. Bars = 50 μm (A, B) and 25 μm (C,D).
