Images showing the effect of IAA treatment on pollen germination. Light microscopical images show pollen grains of Arabidopsis thaliana accession Col-0 (a, b) and the pad2-1 mutant (c, d) after 16 h incubation on solidified pollen germination media containing a, c) 22.8 μM IAA and b, d) 0.1 mM BSO and 22.8 μM IAA. Pollen grains were marked with white circles for better visualization. Bars = 100 μm.
