Abstract:
Specific accumulation of auxin contributes to the regulation of many developmental processes. Auxin uptake is mediated by AUX1 (AUXIN1) and LAX (Like-AUX1) proteins, but their mechanism of action has been unclear. Recent studies by Yang et al. and Ung et al. provide structures suggesting how auxin uptake is coupled to proton flux.
