Title: A TGN/EE-Localized V-ATPase Contributes to Vacuolar Acidification
Abstract: Mature plant cells are characterized by a large tonoplast-bound central vacuole that detoxifies harmful substances and stores ions and metabolites. Vacuolar function depends on massive fluxes of molecules across the tonoplast. These fluxes are energized by two types of proton pumps, vacuolar H+-
