Abstract: Under field conditions, biotic and abiotic stresses usually occur simultaneously, and threaten global food security. Uncovering the mechanisms underlying plant response to combinations of two or more stress conditions holds the potential to breed new crop varieties with enhanced stress tolerance. Recent studies have revealed that the response of plants to stress combinations is unique and cannot be directly extrapolated from the response of plants to each of the different stresses. The responses of plants to different combined stresses might integrate with different signaling pathways at multiple levels, including defence responses, transcription factors, hormone signaling and osmolyte biosynthesis. Here, we review the molecular and physiological responses and adaptations of plants to different stress combinations, and provide an update on multi-omics approaches to study combined stresses.
