Abstract Climate change is increasing the frequency and intensity of overlapping abiotic stresses, making cross-tolerance a critical component of plant resilience. While single stress responses have been extensively characterized, plants in natural and agricultural environments frequently encounter simultaneous or sequential stresses such as drought–heat, light–drought, and drought–salinity, which trigger nonadditive and often unpredictable physiological outcomes that vary with stress intensity, timing, and species. This review synthesizes current understanding of the mechanisms underlying cross-tolerance, emphasizing how contradictory signals, stress timing, and physiological integration shape plant responses under combined stress. We highlight how stomatal regulation, leaf energy balance,… More >
