Abstract

Climate change poses significant challenges to our ability to keep a growing global population fed, clothed, and fuelled. This review sets the scene by summarising the impacts of climate change on production of the major grain crop species rice, wheat, and maize, with a focus on yield reductions due to abiotic stresses and altered disease pressures. We discuss efforts to improve resilience, emphasising traits such as water use efficiency (WUE), heat tolerance, and disease resistance. We move on to exploring production trends of established, re-emerging, and new crops, highlighting the challenges of developing and maintaining new arrivals in the global market. We analyse the potential of wild relatives for improving domesticated crops, or as candidates for de novo domestication. The importance of pangenomes for uncovering genetic variation for crop improvement is also discussed. We examine the impact of climate change on non-cereals, including fruit, nut, and fibre crops and the potential of alternative multiuse crops to increase global sustainability and address climate change-related challenges. Agave is used as an exemplar to demonstrate the strategic pathway for developing a robust new crop option. There is a need for sustained investment in research and development across the entire value chain to facilitate the exploration of diverse species and genetic resources to enhance crop resilience and adaptability to future environmental conditions.

期刊介绍: The Journal of Experimental Botany publishes high-quality primary research and review papers in the plant sciences. These papers cover a range of disciplines from molecular and cellular physiology and biochemistry through whole plant physiology to community physiology. Full-length primary papers should contribute to our understanding of how plants develop and function, and should provide new insights into biological processes. The journal will not publish purely descriptive papers or papers that report a well-known process in a species in which the process has not been identified previously. Articles should be concise and generally limited to 10 printed pages.
