From: A plausible mechanism for auxin patterning along the developing root
Representation in the model the processes influencing the auxin distribution along the central root axis. a. Acropetal flow is considered in the model along the cell array on the central root axis (x axis). Arrows denote the processes that provide for auxin movements considered in the model. b. The summarized mechanism providing for regulation of PIN1 expression comprises the regulation of PIN1 protein synthesis and degradation depending on the auxin concentration.
