Abstract
Climate change detrimentally affects crop yield through increased abiotic (e.g. flooding, drought and heat waves) and biotic (e.g. herbivory) stressors. While often investigated individually, we lack knowledge of the effects of these stressors in combination. I review the morphological and physiological effects of flooding and herbivory on tomato plants, particularly on root and shoot growth, biomass and gene regulation. I also discuss the strategies used by plants to increase tolerance and resistance through adventitious root formation (AR), polyphenol oxidase (PPO) production, initializing the release of volatile organic compounds (VOC), and synthesis of phytohormones like ethylene or jasmonic acid (JA). This review provides insight on the complex nature of multiple stressors on tomato plants, and how their defense strategies can be utilized to create better farming practices and new strains of tolerant tomato cultivars.
