A grand challenge facing plant scientists today is to find innovative solutions to increase global crop production in the context of an increasingly warming climate. A major roadblock to global food sufficiency is persistent loss of crops to plant diseases and insect infestations. The United Nations has declared 2020 as the International Year of Plant Health. For historical reasons, molecular studies of plant-biotic interactions in the past several decades have not paid enough attention to how variable climate conditions affect plant-biotic interactions. Here, we highlight a few recent studies that begin to reveal how major climatic drivers impact the plant immune system, particularly secondary messenger and defense hormone signaling, and discuss possible approaches toward engineering climate-resilient plant immunity as part of an ongoing global effort to design 'dream' crops of the future.
当今植物科学家面临的一项重大挑战是，在气候日益变暖的背景下，寻找创新性的方法来提高全球作物产量。阻碍全球粮食充足供应的一个主要障碍是作物持续受到植物疾病和虫害的影响。联合国宣布 2020 年为国际植物健康年。由于历史原因，过去几十年中对植物-生物相互作用的分子研究没有充分关注气候变化条件如何影响植物-生物相互作用。在这里，我们重点介绍一些最近的研究，这些研究开始揭示主要气候驱动因素如何影响植物免疫系统，特别是第二信使和防御激素信号转导，并讨论了将工程化的气候适应性植物免疫作为未来全球设计“梦想”作物努力的一部分的可能方法。
