Actinonin treatment of Arabidopsis. Seeds (ecotype Col-0) were imbibed and seedlings cultured at room temperature with constant light (50 μmol m⁻² s⁻¹) in 200 μL of Murashige and Skoog basal salts with 0.2% (w/v) phytagel in the wells of a 96-well microtiter plate in the absence (0) or presence of actinonin (concentrations as indicated). Images were taken 2 and 5 d after the seeds were sown. Bars represent 50 μm in all 2-d images plus the 3.2-mm actinonin 5-d image and 5 mm in the 0-, 0.81-, and 1.6-mm actinonin 5-d images.
