Root form and function is key to the productivity of natural and agricultural ecosystems. The growth and development of roots is highly adaptable to the environment. Studies show that species differ in their root system adaptation and function in response to high CO2, which may lead to changes in global species composition in the future. However, knowledge of genetic variation and molecular responses in roots to elevated CO2 is still lacking. This review examines the effects of elevated CO2 on root system and offers perspectives for future research.
