Extracellular vesicles (EVs) are membrane-enclosed nanoparticles that have a crucial role in mediating intercellular communication in mammals by facilitating the transport of proteins and small RNAs. However, the study of plant EVs has been limited for a long time due to insufficient isolation and detection methods. Recent research has shown that both plants and plant pathogens can release EVs, which contain various bioactive molecules like proteins, metabolites, lipids, and small RNAs. These EVs play essential roles in plant-microbe interactions by transferring these bioactive molecules across different kingdoms. Additionally, it has been discovered that EVs may contribute to symbiotic communication between plants and pathogens. This review provides a comprehensive summary of the pivotal roles played by EVs in mediating interactions between plants and microbes, including pathogenic fungi, bacteria, viruses, and symbiotic pathogens. We highlight the potential of EVs in transferring immune signals between plant cells and facilitating the exchange of active substances between different species.
细胞外囊泡 (EVs) 是一种膜封闭的纳米颗粒，在哺乳动物中通过促进蛋白质和小 RNA 的运输，在介导细胞间通讯方面发挥着关键作用。然而，由于缺乏有效的分离和检测方法，植物 EVs 的研究一直受到限制。最近的研究表明，植物和植物病原体都可以释放 EVs，其中包含各种生物活性分子，如蛋白质、代谢物、脂质和小 RNA。这些 EVs 通过在不同的生物界转移这些生物活性分子，在植物-微生物相互作用中发挥着重要作用。此外，还发现 EVs 可能有助于植物和病原体之间的共生通讯。本综述全面总结了 EVs 在介导植物与微生物（包括致病真菌、细菌、病毒和共生病原体）相互作用中的关键作用。我们强调了 EVs 在传递植物细胞间免疫信号和促进不同物种间活性物质交换方面的潜力。
