Summary

Movie presents the dynamics of Figure 2A . (0.31 MB AVI) i.e. Auxin canalization in a 1-dimensional cellular system.

Conditions: 20 linearly aligned cells. Boundary cells are acting as sinks; hence they evacuate or degrade auxin.

At the start of the simulation the cells do not contain auxin. Then the simulation runs until a stable state emerges. The blue and red lines correspond to PIN concentrations at the right and left side of the membranes respectively. The two systems differ only by the way auxin is removed: in (A) we assume that the removal in the sink cells is very efficient whereas in (B) the removal efficiency is limited. This difference leads us to two different stationary patterns in which the auxin gradients are opposite and the sink cells are minima of auxin (A) or maxima (B).
