A MODEL FOR PHOTOSYNTHETIC OSCILLATIONS IN CRASSULACEAN ACID METABOLISM (CAM)

We propose a model of crassulacean acid metabolism (CAM) describing th e varying concentrations of pools of major metabolites by a system of coupled nonlinear differential equations. The model shows regular osci llations in normal day-night cycles and free-running endogenous oscill ations in continuous light. The effect of temperature is incorporated in a realistic way. It leads to the correct dependence of the oscillat ory period length on temperature as compared to experimental observati ons. (C) 1997 Academic Press Limited.
