From: AtRabD2b and AtRabD2c have overlapping functions in pollen development and pollen tube growth
Pollen defects in AtrabD2b , AtrabD2c and AtrabD2b/D2c mutants. A, Fresh pollen was examined by SEM. B, DAPI staining of pollen. Fresh pollen grains were stained with DAPI and photographed under the fluorescence microscope. Arrow indicates a pollen grain from the AtrabD2b/2c mutant that lacks a nucleus. C, IKI staining of pollen, demonstrating reduced staining of the AtrabD2b/2c double mutant pollen compared with wild-type pollen. Scale bars = 10 μm (A); 50 μm (B,C).
