Figure 3. Overexpression of Ann5 increased the resistance of pollen germination and tube growth to BFA.

Representative micrographs of pollen grains and tubes from the Ann5-overexpressing lines growing on Arabidopsis pollen germination medium containing 0.3 µM or 0.6 µM BFA for 3 h in vitro. Medium containing 50 nM DMSO was used as the control. Bar  = 50 µm.
