Climate change is altering our environment, subjecting multiple agroecosystems worldwide to an increased frequency and intensity of abiotic stress conditions such as heat, drought, flooding, salinity, cold and/or their potential combinations. These stresses impact plant growth, yield and survival, causing losses of billions of dollars to agricultural productivity, and in extreme cases they lead to famine, migration and even wars. As the rate of change in our environment has dramatically accelerated in recent years, more research is urgently needed to discover and develop new ways and tools to increase the resilience of crops to different stress conditions. In this theme issue, new studies addressing the molecular, metabolic, and physiological responses of crops and other plants to abiotic stress challenges are discussed, as well as the potential to exploit these mechanisms in biotechnological applications aimed at preserving and/or increasing crop yield under our changing climate conditions.This article is part of the theme issue 'Crops under stress: can we mitigate the impacts of climate change on agriculture and launch the 'Resilience Revolution'?'
气候变化正在改变我们的环境，使全球多个农业生态系统面临非生物胁迫条件（如高温、干旱、洪水、盐碱化、寒冷和/或它们的潜在组合）出现频率增加和强度增强的情况。这些胁迫影响植物的生长、产量和存活，给农业生产力造成数十亿美元的损失，在极端情况下还会导致饥荒、人口迁移甚至战争。由于近年来环境变化速度急剧加快，迫切需要开展更多研究，以发现和开发新的方法及工具，提高作物对不同胁迫条件的适应能力。在本期专题中，我们将讨论有关作物和其他植物对非生物胁迫挑战的分子、代谢和生理反应的新研究，以及在生物技术应用中利用这些机制以在不断变化的气候条件下保护和/或提高作物产量的潜力。本文是专题“胁迫下的作物：我们能否减轻气候变化对农业的影响并发起‘适应能力革命’？”的一部分。
