Auxin reflux between the endodermis and pericycle promotes lateral root initiation.

The EMBO journal - 9 Jan 2013

Abstract excerpt

Lateral root (LR) formation is initiated when pericycle cells accumulate auxin, thereby acquiring founder cell (FC) status and triggering asymmetric cell divisions, giving rise to a new primordium. How this auxin maximum in pericycle cells builds up and remains focused is not understood. We report that the endodermis plays an active role in the regulation of auxin accumulation and is instructive for FCs to...
