Fitting the shape, angle, and direction of circumnutations. A. The top view of the trajectory of circumnutation of the hypocotyls of one-week old Helianthus annuus. The example of seedling number 14 on Additional file 1: Video 1. The beginning and end of the circumnutation trajectory are marked by colour gradients from red to blue line B. Shape, angle, and direction of circumnutations number 2–7 (also in a Table 2). C. Arrangement of circumnutation angles in the geographical direction plane. D. Subsequent circumnutations with a marked shape (ellipse, white line), angle (blue line), and direction of circumnutations. In the geographic direction plane, the single circumnutation cycle is determined by two subsequent maximum northward bends of the hypocotyl.
