Plant Acupuncture: Sticking PINs in the Right Places

Nicholas J. Kaplinsky and M. Kathryn Barton

The plant hormone auxin is involved in numerous growth and developmental processes. 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.).
