Association between water and carbon dioxide transport in leaf plasma membranes: Assessing the role of aquaporins

Zhao, Manchun; Tan, Hwei-Ting; Scharwies, Johannes; Levin, Kara; Evans, John; Tyerman, Stephen D


The role of some aquaporins as CO2 permeable channels has been controversial. Low CO2 permeability of plant membranes has been criticized because of unstirred layers and other limitations. Here we measured both water and CO2 permeability (Pos, PCO2) using stopped flow on plasma membrane vesicles (pmv) isolated from Pisum sativum (pea) and Arabidopsis thaliana leaves. We excluded the chemical limitation of carbonic anhydrase (CA) in the vesicle acidification technique for PCO2 using different...[Show more]
