Control theory and kinematical models predict that posture stabilization additionally requires active counter\u2010curving. This led to the hypothesis that plants actively straighten through proprioception (curvature sensing) driving autotropic actuation. However, passive springback can be involved, especially in woody stems, and direct conclusive experimental evidence for proprioception\u2010driven autotropism has been lacking.<\/jats:p>\n                      <\/jats:list-item>\n                      <jats:list-item>\n                        <jats:p>\n                          To assess this hypothesis, we designed a novel experimental setup, allowing us to suspend phototropic and gravitropic sensing on demand along the tropic movement.
