Photosynthesis is a highly regulated, multistep process. It is the source of food, fuel, and fiber and there is a resurgent interest in basic research on photosynthesis. Online first articles listing for Photosynthesis Research. As a result of their efforts, the scientists are now closer than ever to being able to design electron transfer systems in which they can send an electron down a pathway of their choosing. In photosynthetic organisms, these processes begin with the absorption of a photon of light by pigments localized in proteins. Photosynthesis has evolved to work as well as it needs to — for plants. Most life forms on Earth are directly or indirectly dependent on photosynthesis. Abstract. Plant photosynthesis relies on diffusion of CO 2 from the atmosphere to the chloroplasts through the stomatal pores. Soc. SI: Regulation of Chloroplast Primary Metabolism. Photosynthesis involves the use of energy, water, and carbon dioxide to produce energy and organic compounds. Here we report a negative transcription factor of photosynthesis, which can be manipulated to increase rice photosynthesis and plant biomass in the field. To explore the role of receptor-like kinases in the regulation of photosynthesis, an uncharacterized TaRKL1 encoding a receptor-like cytoplasmic kinase was investigated in Triticum aestivum cv.
