The cell layouts in the 2D models of auxin distribution. a. The cell layout in the 2 D minimal model represented by two layer types - provascular (green) and epidermal (gray). b. The cell layout of the model described in . c. The whole set of cell types considered in the models (a, 1 and 2) and (b, 1-5). Red unidirectional arrows in (c.) mark the directions of active auxin transport for each kind of cell. Black bidirectional arrows mark the auxin exchange by diffusion. Auxin flows in a.-b. are delineated by thick red arrows.
