Interpretive Summary: Plants growing under field conditions are often exposed to multiple abiotic factors such as water stress, temperature extremes, soil salinity and biotic factors such as pathogens, pests and parasites simultaneously or sequentially. Most basic research on stresses have dealt with a single stressor at a time. In recent years, the importance of conducting research on two or more stresses has gained traction. In this report we review the literature on combined stresses highlighting major gaps and novel avenues for further research on this important topic.

Technical Abstract: Plants growing under field conditions are often exposed to multiple abiotic and biotic stresses occurring simultaneously or sequentially. Biotic stressors often interact with abiotic stressors at the plant interphase which makes the impact of their combination on plants remarkably variable, though differing with order and intensity of stresses, as well as plant species and pathotypes. The major abiotic stress combinations as well as abiotic-biotic stress combinations and physiological and molecular responses of plants to these combined insults are examined. Utilizing the available literature information on phenomic and transcriptomic response of plants to the combined abiotic and biotic stresses, the crosstalk during signaling is reviewed. A succinct discussion on the scope and application of combined abiotic and biotic stress studies highlighting major gaps and novel avenues for further research is articulated.
