Parsimonious Model of Vascular Patterning Links Transverse Hormone Fluxes to Lateral Root Initiation: Auxin Leads the Way, while Cytokinin Levels Out
Fig 12
Xylem-pole pericycle cells compete for auxin accumulation in simulations of geometric cross sections.
A simultaneous 120-second pulse of AUX1 activation in two pericycle cells marked with asterisks (A, D, G, J) results in auxin accumulation in only one cell. In simulations with apolar PIN1 and PIN7, the same cell accumulates auxin (B, E, H, K), whereas the identity of the winning cell varies in simulations with polar PIN1 and PIN7 (C, F, I, L).
