Physiological and iTRAQ based proteomics analyses reveal the mechanism of elevated CO2 concentration alleviating drought stress in cucumber (Cucumis sativus L.) seedlings

Carbon dioxide is one of the most important anthropogenic greenhouse gases. We previously confirmed that elevated [CO2] alleviated the negative consequences of drought stress to cucumber seedlings, but the physiological mechanism remains unknown. We investigated the morphological and physiological characteristics as well as iTRAQ-based proteomics analyses in this study under different combinations [CO2] (400 and (800 ± 20) μmol·mol−1) and water...
