Extraction of mechanical forces during hyperbending and meaningful model parameters. (a) Schematic illustration of the mechanical model. (b) Calculation process of stem dynamics. After mechanical equilibrium at the current time, the intrinsic curvature along the stem is renewed and reaches the next mechanical equilibrium. (c,d) A representative stem bending with colored spatio-temporal curvature on top of actual stem data (gray) for wild type (c) and for myosin xif xik (d). The green cross mark denotes the supporting point mentioned in the main text. Right panels show the color plots of the curvature as a function of time (min) and curvilinear coordinate (mm). (e,f) Extracted stretching and bending forces for wild type (e) and for myosin xif xik (f). (g) Plot of gravitropic response β and proprioceptive response γ. (h) Boxplots of β and γ.
