Abstract
Ferricyanide reduction by epidermal strips of Commelina communis is stimulated by plasmolysis, and this stimulation is partially reversed by re-hydration. The reduction of ferricyanide takes place only in the guard cells.KCN stimulates ferricyanide reduction, indicating that NADH serves as an electron donor. Catalase, which inhibits NAD(P)H driven oxygen uptake [Askerlund et al. (1987) Physiol. Plant. 71: 9-19., Pantoja and Willmer (1988) Planta 174: 44-50.] enhances ferricyanide reduction and this stimulation is evident mainly in the non-plasmolysed tissues. Differences between the non-pretreated tissues and the plasmolysed ones are discussed.
