The influence of noise is unavoidable in all living systems. Its impact on a model of a biological clock, normally running in regular oscillating modes, is examined. It is shown that in a specific system in which endogenous rhythmicity is produced by …
The mechanism of endogenous circadian photosynthesis oscillations of plants performing crassulacean acid metabolism (CAM) is investigated in terms of a nonlinear theoretical model. Unlike previous CAM models containing a discrete element, we use …
We propose a simple oscillatory model of crassulacean acid metabolism (CAM) describing the CO2 uptake and nocturnal acidification of CAM plants by a system of coupled non‐linear differential equations. Large differences in the content of metabolite …
The observed endogenous circadian rhythm in plants performing Crassulacean acid metabolism is effected by malate transport at the tonoplast membrane. Experimental and theoretical work asks for a hysteresis switch, regulating this transport via the …
We propose a model of crassulacean acid metabolism (CAM) describing the varying concentrations of pools of major metabolites by a system of coupled nonlinear differential equations. The model shows regular oscillations in normal day night and …
The amounts of mRNA of subunit-c (proteolipid) of the V-ATPase of mature leaves of Mesembryanthemum crystallinum L. in the state of C3-photosynthesis were analyzed for a time-series of 96 h under constant conditions in continuous light. …
Net CO2 exchange (Jco2) of leaves of the CAM plant Kalanchoë daigremontiana Hamet et Perrier de la Bǎthie was studied in continuous light under the influence of temperature jumps of different period lengths. Each period consisted of two equal time …
