ABSTRACT
The light and CO2 response curve of photosynthesis is an important tool to study plant physiology and plant ecology that can provide a scientific basis for the response of plant photosynthetic properties to environmental factors. This review considered the progress and potential weaknesses of light and CO2 response models of photosynthesis and discussed research trends. Photosynthesis, which involves energy of light, absorption, energy conversion, electron transfer, ATP synthesis, CO2 fixation etc., is a complex physical and chemical reaction process. It includes three basic steps: the primary reaction, the assimilatory power forms and the carbon assimilation, and each link may directly influence other processes. Classical models on photosynthetic light response only involve withlight energy absorption, and biochemistry models do with the assimilatory power to form as well as carbon assimilation. A future direction of research of the mechanistic model of photosynthetic light response is the primary reaction of photosynthesis, namely participation the energy of light absorption, the transmission and the transformation of the harvesting light pigment member the physical parameter (e.g., the light-harvesting pigment molecules, light energy absorption cross-section of the harvesting pigment, the mean lifetime of the harvesting light pigment) unify in the biochemistry model.
