Light-induced polar pH changes in leaves of Elodea canadensis. II. Effects of ferricyanide: evidence for modulation by the redox state of the cytoplasm

The effect of an extracellular electron acceptor, ferricyanide, on the light-induced polar leaf pH changes of the submerged angiosperm Elodea canadensis in light and in darkness was determined. The rate of transmembrane ferricyanide reduction was stimulated by increased light intensity and was inhib...
