Fig. 8. Effects of vesicle and cytoskeletal inhibitors on wild type and scd1 root growth and cell morphogenesis. CLSM optical sections of wild type (wt), scd1-1 and scd1-2 roots grown in (A) the absence and (B-E) the presence of caffeine (B), brefeldin A (C), latrunculin B (D) and propyzamide (E). The graph associated with each image represents the extent of root growth (y-axis; mm) over a 4- to 5-day period in the absence and presence of the inhibitors at the indicated concentrations (x-axis). The asterisk denotes the inhibitor concentration used in the underlying root section. 5-15 seedlings were measured for each treatment and genotype. Scale bars: 50 µm.
