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.

待售新作物:面对日益动荡的农业系统,扩大粮食、纤维和燃料储备的有效战略。
气候变化对我们维持不断增长的全球人口的温饱和燃料供应的能力提出了重大挑战。这篇综述概述了气候变化对主要粮食作物品种水稻、小麦和玉米生产的影响,重点介绍了由于非生物胁迫和疾病压力改变而导致的产量下降。我们讨论了提高恢复力的努力,强调水分利用效率(WUE)、耐热性和抗病性等性状。我们继续探索已建立的、重新出现的和新作物的生产趋势,强调在全球市场上开发和维护新产品的挑战。我们分析了野生近缘种改良驯化作物的潜力,或作为重新驯化的候选者。文中还讨论了泛基因组在揭示遗传变异和作物改良方面的重要性。我们研究了气候变化对非谷物作物的影响,包括水果、坚果和纤维作物,以及替代多用途作物在提高全球可持续性和应对气候变化相关挑战方面的潜力。龙舌兰被用作一个例子来展示开发一种强大的新作物选择的战略途径。需要对整个价值链的研发进行持续投资,以促进对多样化物种和遗传资源的探索,从而提高作物的抗灾能力和对未来环境条件的适应能力。

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.
