Polyamines (PAs), which are aliphatic polycationic compounds with a low molecular weight, are found in all living organisms and play essential roles in plant-pathogen interactions. Putrescine, spermidine, and spermine, the most common PAs in nature, respond to and function differently in plants and pathogens during their interactions. While plants use certain PAs to enhance their immunity, pathogens exploit PAs to facilitate successful invasion. In this review, we compile recent studies on the roles of PAs in plant-pathogen interactions, providing a comprehensive overview of their roles in both plant defense and pathogen pathogenicity. A thorough understanding of the functions of PAs and conjugated PAs highlights their potential applications in fungicide development. The creation of new fungicides and compounds derived from PAs demonstrates their promising potential for further research and innovation in this field.
多胺（PAs）是一种具有低分子量的脂肪族多阳离子化合物，存在于所有生物体中，在植物-病原体相互作用中发挥着重要作用。腐胺、亚精胺和精胺是自然界中最常见的 PAs，它们在植物和病原体相互作用中对其做出响应并发挥不同的作用。植物利用某些 PAs 来增强其免疫力，而病原体则利用 PAs 来促进成功入侵。在这篇综述中，我们汇编了最近关于 PAs 在植物-病原体相互作用中的作用的研究，全面概述了它们在植物防御和病原体致病性中的作用。深入了解 PAs 和共轭 PAs 的功能突出了它们在杀菌剂开发中的潜在应用。新杀菌剂和 PAs 衍生化合物的创制展示了它们在该领域进一步研究和创新的广阔前景。
