Participation of endomembrane cation/H+ exchanger AtCHX20 in osmoregulation of guard cells.

Plant physiology - 1 May 2007

Abstract excerpt

Guard cell movement is induced by environmental and hormonal signals that cause changes in turgor through changes in uptake or release of solutes and water. Several transporters mediating these fluxes at the plasma membrane have been characterized; however, less is known about transport at endomembranes. CHX20, a member of a poorly understood cation/H+ exchanger gene family in Arabidopsis (Arabidopsis thaliana),...
