author keywords: BY2; Lipid; Osmotic water permeability coefficient; P-f; Signaling; Synthetic-biology
MeSH headings : Aquaporins / metabolism; Cell Membrane Permeability; Cells, Cultured; Cytosol / metabolism; Hydrogen-Ion Concentration; Phosphatidylinositols / metabolism; Protoplasts; Tobacco; Water / metabolism
