text: Phytohormone auxin and its directional transport mediate much of the remarkably
plastic development of higher plants. Positive feedback between auxin signaling
and transport is a key prerequisite for (i) self-organizing processes including
vascular tissue formation and (ii) directional growth responses such as gravitropism.
Here we identify a mechanism, by which auxin signaling directly targets PIN auxin
transporters. Via the cell-surface ABP1-TMK1 receptor module, auxin rapidly induces
phosphorylation and thus stabilization of PIN2. Following gravistimulation, initial
auxin asymmetry activates autophosphorylation of the TMK1 kinase. This induces
TMK1 interaction with and phosphorylation of PIN2, stabilizing PIN2 at the lower
root side, thus reinforcing asymmetric auxin flow for root bending. Upstream of
TMK1 in this regulation, ABP1 acts redundantly with the root-expressed ABP1-LIKE
auxin receptor ABL3. Such positive feedback between cell-surface auxin signaling
and PIN-mediated polar auxin transport is fundamental for robust root gravitropism
and presumably also for other self-organizing developmental phenomena.
