Fig. 2. — Redistribution of IAA in coleoptiles after photo-stimulation. IAA redistribution during phototropic curvature under normal gravity conditions (0–60 min), and under microgravity conditions on a clinostat after photo-stimulation (60 min). Endogenous free IAA was extracted from each 3 mm section from the top to the basal parts of the shaded and irradiated sides of the coleoptiles after photo-stimulation and IAA levels were determined by GC-SIM-MS. White bar, irradiated side of the coleoptiles; black bar, shaded side of the coleoptiles. Data and error bars represent means ±SE (15≤n≤27).
