Mitotic activity in the root and its simulation. a. The scheme of root tip structure in Arabidopsis. The cells of different types
marked by different colors (for details, see figure 1). b. Qualitative profile of
mitotic activity in cells along the central root axis. Two maxima of mitotic activity
are distinguished along the central root axis according to Dolan et al. (1993) [1] and Beemster and Baskin (2000) [27]. c. The model solution: auxin (red squares) and substance Y (blue circles) distributions
regulate the rates of cell divisions in the root (gray columns). The dynamical characteristics
(cell coordinates on the axis, auxin concentration, and division rates) in the model
solutions reproduce root patterning, where the cells of different types are specifying
around the distal auxin maximum. d. The plot of auxin-regulated Y degradation rate
used in the model (Eq. (8)). (E) The plot of Y-regulated rates of cell division (first
coefficient in Eq. (10)). QC is the quiescent center and RCI is the root cap initial.
