Accumulation of malate in guard cells of Vicia faba during stomatal opening

, : Accumulation of malate in guard cells of Vicia faba during stomatal opening. Planta 110(1): 63-70

The level of malate in the epidermis from illuminated leaves of V. faba was greater than in that from dark-treated leaves. A difference in the malate level was still detected after the epidermis had been treated by rolling so that only the guard cells remained alive. Results suggested that malate might accumulate in guard cells on illumination. In subsequent experiments, stomatal apertures were measured, and K as well as malate was analysed in extracts of epidermis.
