    Effects of Ca 2+ on taxol-induced haptonematal bending. (A) A phase contrast image of a haptophyte treated with taxol (20 μM) in the absence of Ca 2+ (CFSW+EGTA+BAPTA-AM) showing a helical configuration of the haptonema (left). The plot to the right shows the curvature along the haptonema (see Fig. S5 ). The curvature of the haptonema was calculated from the microscopic image, which is a two-dimensionally projected image. The curvature of a helical structure calculated in this way shows oscillation with a repeat distance equivalent to that of the helix, and a shift in the pattern represents propagation of the wave form. Scale bar: 10 µm. (B) Ca 2+ -dependent propagation of a taxol-induced haptonematal helix. The helix is also converted to planar bending with the maximum curvature of bend propagating to the proximal region. Trace images of haptophytes are shown as insets.
