Image analysis of shoot gravitropism over time. (a,f) Time-lapse images of shoot gravitropism for wild type (t = 0, 100, 200 min) (a) and for myosin xif xik (f). Scale bars 20 mm. (b,c,g,h) Color diagrams of the inclination angle of the stem as a function of time (min) and curvilinear coordinates (mm) for wild type (b,c) and for myosin xif xik (g,h). (d,e,i,j) Color diagrams of the curvature of the stem as a function of time (min) and curvilinear coordinate (mm) for wild type (d,e) and for myosin xif xik (i,j).
