The atmospheric CO2 concentration has been predicted to reach 550–750?μmol mol?1 by 2050, or twice as high as the current level. Much of the research in the last 20–30?years concerning elevated CO2 (eCO2) has been about how plants would respond to the eCO2 at physiological levels. As eCO2 can lead to more frequent drought or extreme high or low temperature, increasingly more research has focused on the interactions between eCO2 and other abiotic stresses. How stresses may affect plant growth and development and productivity, as well as how agricultural practices may be altered to cope with these changes must be determined. These concerns have been the subject of numerous reviews. However, it is only in the last several years that data at the “omics” levels has been available to explore how necessary physiological changes may be brought about in a future complex environment. The systems biology approaches provide us an insight into the mechanism of plant responses to climatic changes at the genomics level. In this review, we present an overview of physiological effects of eCO2 on plants, but focus on the interactions of eCO2 with drought, high temperature, O3, and multiple abiotic stresses, with particular emphasis at the molecular and genomics levels. We also provide perspectives on future research and emphasize the importance of integrated research on eCO2 and multiple environmental stresses using systems biology approaches. 收起<<
