In Vivo Intracellular pH Measurements in Tobacco and Arabidopsis Reveal an Unexpected pH Gradient in the Endomembrane System

2013

This work combines biochemistry and live-cell imaging to perform in vivo pH measurements of different compartments of the endomembrane system in plant cells. It reports that the prevacuolar compartments are more alkaline than the trans -Golgi network and provides evidence that endosomal proton pumps and proton efflux transporters contribute to pH homeostasis.
