Subcellular homeostasis of phytohormone auxin is mediated by the ER-localized PIN5 transporter

Original language description

The plant signalling molecule auxin provides positional information in a variety of developmental processes by means of its differential distribution within plant tissues. Transmembrane transport and metabolic processes regulate the steady-state levels of auxin in any given cell. In particular, PIN directional transport between cells is crucial for generating auxin gradients. Here we show that Arabidopsis thaliana PIN5 encodes a functional auxin transporter that is required for auxin-mediated development. PIN5 localizes to endoplasmic reticulum (ER), presumably mediating auxin flow from the cytosol to the lumen of the ER. The ER localization of other PIN5-like transporters indicates that the diversification of PIN protein functions in mediating auxin homeostasis at the ER, and cell-to-cell auxin transport at the plasma membrane, represent an ancient event during the evolution of land plants.
