Abstract: Unicellular green algae plays a key role in freshwater ecosystem, which possesses a CO2 concentrating mechanism that can increase the level of CO2 at the active site of ribulose bisphosphate-carboxylaseoxygenase (Rubisco) by actively transporting inorganic carbon when adapted to low CO2 concentration.The mechanism results in an increase in photosynthetic rate,and a decrease in photorespiration. This mechanism and its environmental regulation such as light, temperature, CO2 concentration and nutrient are reviewed in this paper to enhance further studies on response of phytoplankton to elevated atmospheric CO2 concentration in China.
