“…In fact, cultivars that show higher increases in cuticle thickness under drought are considered drought tolerant (Bi et al, 2017). Additionally, work in Arabidopsis has shown mutant lines (aldh2c4 ) with a 50% reduction in leaf cuticle thickness have higher water loss than wild type plants (Liu et al, 2022). Alterations in leaf thickness under drought stress also works to better regulate the balance between CO 2 acquisition and water loss (Li et al, 2021).…”

As sessile organisms, plants are constantly challenged by a dynamic growing environment. This includes fluctuations in temperature, water availability, light levels, and atmospheric conditions. In concert with changes in abiotic conditions, plants experience changes in biotic stress pressures, including plant pathogens, viruses, and herbivores. Human-induced increases in atmospheric carbon dioxide (CO ) levels have led to alterations in plant growth environments that challenge their productivity and nutritional quality. Additionally, it is predicted that climate change will alter the prevalence and virulence of plant pathogens, further challenging plant productivity. A knowledge gap exists in the complex interplay between plant responses to biotic and abiotic stress conditions. Closing this gap is crucial for developing climate resilient crops in the future. Here, we review the physiological responses of plants to elevated CO , temperature, tropospheric ozone (O ), and drought conditions, as well as the interaction of these abiotic stress factors with plant pathogen pressure. Additionally, we describe the crosstalk and trade-offs involved in plant responses to both abiotic and biotic stress, and outline targets for future work to develop a more sustainable future food supply in light of future climate change.
