โœฆ Synopsis

The metabolic pathways in photosynthesis are modelled as an interconnected series of chemical reactions representing the electron transfer system, the carbon reduction cycle and starch and sucrose synthesis according to the model of Laisk and Walker [Proc R Soc Lond 22.7, 281-302 (1986)]. The model is formulated as a set of non=linear differential equations using mass-action kinetics, and stimulated for transient behaviour using an interactive simulation language. The model responses to switched light demonstrate the existence of oscillatory behaviour, similar to that found experimentally in 02 evolution and chlorophyll fluorescence, and explain known transient behaviour. The model is also used to investigate the source of oscillatory behaviour in the phosphate translocator, and other transient phenomena associated with the cyclic electron transfer system.

When spinach leaves are re-illuminated, after dark periods of 90 s or less, an initial fluorescence peak is observed which rapidly gives way to a much lower terminal value. After 2 min or more in the dark, however, there is a secondary rise, at about 50-70 s, which then gives way, more slowly, to ap

The aim of this work was to examine the effect of temperature in the range 5 to 30 ~ C upon the regulation of photosynthetic carbon assimilation in leaves of the C4 plant maize (Zea mays L.) and the C3 plant barley (Hordeum vulgare L.). Measurements of the CO2-assimilation rate in relation to the te
