Figure 3.

Graph showing curvature angles of control cells, which were continuously gravistimulated for 120 min at 90° on ground (white bar; n = 69) and of rhizoids that were horizontally positioned for 120 min on ground and intermittently centrifuged 62 times for 22 s at 2g (gray bar; n = 59). Not significantly different curvature values of controls and centrifuged samples (Student's t test, P = 0.8136) provide evidence that increasing the weight of sedimented statoliths by repeated short-term centrifugation does not affect gravitropic curvature. Data represent means ± se.
