Abstract
As is well known, CAM plants open stomata at night and close them during the day to save water in regions characterized by periodic drought, hot days and cooler nights (see reviews by Winter 1985; Lüttge 1987; Griffiths 1988; Leegood and Osmond 1990; Smith and Bryce 1992). At night, they permit entry of atmospheric CO2, which is transiently stored in the vacuole in the form of a carboxylic group of malic acid. In the light, malate is released from the vacuole and decarboxylated in the cytosol, usually behind closed stomata. The Calvin cycle of the chloroplasts and associated reactions then take care of the decarboxylation products CO2 and pyruvate, which are converted into carbohydrates.
