Models of root transport. (A–F) Model from Grieneisen et al. (Grieneisen et al. 2007) showing that specific static localization of PIN efflux mediators is sufficient to create a reflux loop and generate an auxin peak at the quiescent center.

(Jones et al. 2008). Adapted by permission from Macmillan Publishers Ltd.:Nature Cell Biology (Jones et al. 2008), copyright (2008). (G) Visualization of the template used in the simulations. (H–J) Auxin distribution in epidermal cells. Red is nonroot-hair cells and blue is root-hair cells auxin concentrantion for wild-type (H) and aux mutant (I, J) simulations. The difference between (I) and (J) is in the amount of auxin supplied to the tissue.
