During their development, many plants display a revolving movement, the circumnutation. In spite of its ubiquity, plant nutation has not received as much attention as other plant movements, and its underlying mechanism remains unclear. Here we show that a simple relation between curvature and differential growth can be revealed. This sheds a new light on classical measurements where only the movement of the apical tip was measured. The relation between the observed pattern and the growth dynamics is not unique, and the full kinematics of the organ in 3 dimensions should be acquired. See See Bastien, Meroz.
