Ammonium-induced loss of root gravitropism is related to auxin distribution and TRH1 pathway.
Title: Ammonium-induced loss of root gravitropism is related to auxin distribution and TRH1 function, and is uncoupled from the inhibition of root elongation in Arabidopsis.
Disruption of the TRH1 potassium transporter impairs root hair development in Arabidopsis, and also affects root gravitropic behaviour.
Title: Potassium carrier TRH1 is required for auxin transport in Arabidopsis roots.
