Simulation of root growth along the central root axis. In the figure, (a) Distribution of auxin (red), Y (blue) and rates of cell division (gray columns) in conventional units along the central root axis. The curves were calculated in the 1 D minimal model with basic set of parameters. (b-d) The extended model solutions: (b) The mitotic activity along the central root axis; (c-f). Auxin and substance Y distribution. The green curve indicates the growth mode of cells (1- idle, 0- growth). c. the model was started from three cells; d. 10 cells; e. 20 cells; (f.) more than 100 cells. Cells of different types can be distinguished by considering both auxin concentration in the cell and its mitotic activity (see the main text for more details): QC - quiescent center; RCI - root cap initial; RC- root cap; MZ- meristematic zone; DZ- differentiation zone.
