| Abstract | Climate change increasingly threatens plant growth and productivity. Soybean (Glycine max) is one of the most important crops in the world. Although its responses to increased atmospheric carbon dioxide concentration ([CO2]) have been previously studied, root molecular responses to elevated [CO2] (E[CO2]) or the combination/interaction of E[CO2] and water deficit remain unexamined. In this study, we evaluated the individual and combinatory effects of E[CO2] and water deficit on the physiology and root molecular responses in soybean. Plants growing under E[CO2] exhibited increased photosynthesis that resulted in a higher biomass, plant height, and leaf area. E[CO2] decreased the transcripts levels of genes involved in iron uptake and transport, antioxidant activity, secondary metabolism and defense, and stress responses in roots. When plants grown under E[CO2] are treated with instantaneous water deficit, E[CO2] reverted the expression of water deficit-induced genes related to stress, defense, transport and nutrient deficiency. Furthermore, the interaction of both treatments uniquely affected the expression of genes. Both physiological and transcriptomic analyses demonstrated that E[CO2] may mitigate the negative effects of water deficit on the soybean roots. In addition, the identification of genes that are modulated by the interaction of E[CO2] and water deficit suggests an emergent response that is triggered only under this specific condition. | pt_BR |
