Abstract

The limited diversity and recognition scope of natural plant immune receptors impede resistance breeding against rapidly evolving pathogens. Here, we report the programmable design of synthetic plant immune receptors (SPIRs). De novo–designed binding modules targeting pathogen proteins were grafted into the integrated decoy domain of a plant immune receptor. SPIRs recognized proteins derived from viral, bacterial, fungal, and oomycete pathogens. Their performance was improved by combining artificial intelligence–guided protein design with in planta–directed evolution, enhancing immune activation while reducing autoactivation. The SPIRs exhibited high target specificity and could be stacked for multiplexed recognition of pathogen proteins. Viral-targeting SPIRs responded to infectious clones of plant viruses, and transgenic plants expressing SPIRs conferred disease resistance. This work establishes a versatile platform for the efficient engineering of plant immunity.

病原体蛋白识别合成植物免疫受体的可编程设计

天然植物免疫受体的多样性和识别范围有限，阻碍了对快速进化的病原体的抗性育种。本文报道了合成植物免疫受体（SPIRs）的可编程设计。将重新设计的靶向病原体蛋白的结合模块嫁接到植物免疫受体的整合诱饵（ID）结构域。SPIRs识别来自病毒、细菌、真菌和卵菌病原体的蛋白质。通过将人工智能引导的蛋白质设计与植物定向进化相结合，增强了免疫激活，同时减少了自身激活，从而提高了它们的性能。SPIRs具有较高的靶向特异性，可堆叠用于病原体蛋白的多重识别。重要的是，病毒靶向的SPIRs对植物病毒的感染性克隆有反应，表达SPIRs的转基因植物具有抗病能力。这项工作为高效的植物免疫工程建立了一个通用的平台。

期刊介绍： Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
