Understanding how plants fend-off invading microbes is essential for food security and the economy of large parts of the world. Consequently, a sustained and dedicated effort has been directed at unveiling how plants protect themselves from invading microbes. Major defense hormone signaling pathways have been characterized, the identity of many immune response-triggering molecules as well as many of their receptors have been determined, and the mechanisms of pathogen-host arms race are being studied. In recent years, evidence for a new layer of plant innate immunity involving transition metals has been brought forward. This would link plant metal nutrition with plant immune responses and open up possible new strategies for pathogen control involving metal fertilizers instead of pesticides. In this review, we outline our current understanding of metal-mediated plant immune response and indicate the future avenues of exploration of this topic.
了解植物如何抵御入侵微生物对于全球大部分地区的粮食安全和经济至关重要。因此，人们持续投入了大量精力来揭示植物如何保护自身免受入侵微生物的侵害。主要的防御激素信号通路已被阐明，许多引发免疫反应的分子及其众多受体的身份已被确定，病原体与宿主军备竞赛的机制也正在研究之中。近年来，有证据表明植物先天免疫存在涉及过渡金属的新层面。这将把植物金属营养与植物免疫反应联系起来，并开辟出可能涉及金属肥料而非农药的病原体控制新策略。在本综述中，我们概述了目前对金属介导的植物免疫反应的理解，并指出了该主题未来的探索方向。
