-Title-
Dynamic Regulation of Photosynthesis in Chlamydomonas reinhardtii
-Authors-
Jun Minagawa and Ryutaro Tokutsu
-Summary-
Plants and algae have acquired the ability to acclimate to ever-changing environments to survive. During photosynthesis, light energy is converted by several membrane protein supercomplexes into electrochemical energy, which is eventually used to assimilate CO2. The efficiency of photosynthesis is modulated by many environmental factors, including temperature, drought, CO2 concentration, and quality and quantity of light. Recently, our understanding of such regulators of photosynthesis and the underlying molecular mechanisms has increased considerably. The photosynthetic supercomplexes undergo supramolecular reorganizations within a short time after receiving environmental cues. These reorganizations include state transitions that balance the excitation of the two photosystems, qE quenching that thermally dissipates excess energy at the level of the light-harvesting antenna, and cyclic electron flow that supplies the increased ATP demanded by CO2 assimilation and the ΔpH to activate qE quenching. This review will focus on recent findings regarding the environmental regulation of photosynthesis in model organisms, paying particular attention to the unicellular green alga Chlamydomonas reinhardtii, which offers a glimpse into the dynamic behavior of photosynthetic machinery in nature.
