Video 19. Stimulation of pollen (Landsberg accession) germination by sulfinylated azadecalins.

Time-lapse imaging of Arabidopsis pollen (Landsberg accession) germination on a solid pollen growth medium. Pollen grains from the same anther were spotted proximal to three holes, one filled with 50 μM N-Methanesulfinyl 1-azadecalin, a second one filled with 50 μM N-Methanesulfinyl 2-azadecalin and a third one filled with liquid PGM (control). The pollen growth medium was prepared as described in (Li et al., 1999). Time elapsed between two frames in each movie–two minutes (00:02hrs)–is indicated on the top left hand corner and the scale bar (100 μm) is shown on the bottom right corner of each frame.
