Figure 6. A. Steady-state shape of the $A_R^{a}C$ model for D = 4.

The black line is the solution when B = 0. As B increases (solid colored line from red to blue), the orientation and the shape of the organ is modified. The dashed line shows the steady-state shape of the graviceptive equation. The expected orientation of the organ A _R is shown at the bottom. B. Steady-state shape of the $A_R^{a}C$ model for B = 4. The black line is the solution when D = 0. As D increases (solid colored line from red to blue), the organ’s orientation and shape are modified. The dashed line shows the steady-state shape of the photoceptive equation, A^aC model. The expected orientation of the organ A _R is shown at the bottom.
