These processes all depend on differences in local auxin concentrations that are established by polar auxin transport. In their Perspective, Kaplinsky and Barton discuss new work that identifies a serine-threonine kinase called PID as a switch that regulates auxin flow by redirecting the cellular localization of auxin transport facilitator (PIN) proteins ( Friml et al.).
