The auxin distribution pattern reproduced by the model. a. Expression of DR5::GUS detects the auxin pattern in the root tip (adapted from Sabatini et al., 1999; ). b. The surface plot of DR5 activity in the root tip scanned from figure 2a by ImageJ program. The x axis corresponds to the central axis of the root; the root width extends along the y axis; and the z axis shows DR5 activity. c. The model solution (black line) agrees well with semi-quantitative data of auxin distribution along the central root axis, obtained from the surface plot at figure 2b (red line). d. The auxin distribution pattern in the stationary solution of the 2D minimal model. Blue arrowhead denotes the QC position.
