From: Glutathione synthesis is essential for pollen germination in vitro
Statistical analysis of the subcellular distribution of glutathione in pollen grains of Col-0. Total amount of gold particles bound to glutathione per μm2 in pollen grains of Arabidopsis thaliana accession Col-0. Pollen grains were incubated for 5 hours on solidified pollen germination media containing different concentrations of BSO (0.1 mM) and GSH (1 or 3 mM). Data represent means and standard errors. Different lowercase letters indicate significant differences (P < 0.05) analyzed with the Kruskal-Wallis test followed by post-hoc comparison according to Conover. N > 20 pollen grains per treatment from 2 independent experiments.
