Figure 1From: Glutathione synthesis is essential for pollen germination in vitroImages showing the effect of BSO and GSH treatment on pollen germination in Col-0. Light microscopical images show Arabidopsis thaliana accession Col-0 pollen grains after 16 h incubation on solidified pollen germination media containing (a) no GSH and BSO (control), (b) 0.1 mM BSO, (c) 0.1 mM BSO and 1 mM GSH, and (d) 0.1 mM BSO and 3 mM GSH. Original images were inverted and germinating pollen grains were marked with white circles for better visualization. Bars = 100 μm.Back to article page
