Phenotypic responses of plants to biotic and abiotic stresses are frequently studied as the outcome of interactions between plants and one or two species of microbes or a single abiotic stress. However, in the phytobiome, plant health and productivity is impacted by simultaneous interactions among multiple organisms and the environment, and frequently, the responses to these interactions are distinct and would not be predicted from studying less complex systems. In this presentation, examples of multitrophic interactions among bacteria, insects, and plants, as well as interactions involving bacteria, plants, and temperature will be used to demonstrate the difficulty in predicting outcomes from simultaneous stresses. Developing successful and sustainable crop improvement and management strategies for the future will benefit from studying these interactions as a system.
