Potassium carrier TRH1 is required for auxin transport in Arabidopsis roots.

The Plant journal : for cell and molecular biology - 1 Nov 2004

Abstract excerpt

Disruption of the TRH1 potassium transporter impairs root hair development in Arabidopsis, and also affects root gravitropic behaviour. Rescue of these morphological defects by exogenous auxin indicates a link between TRH1 activity and auxin transport. In agreement with this hypothesis, the rate of auxin translocation from shoots to roots and efflux of [3H]IAA in isolated root segments were reduced in the trh1...
