Extracellular vesicles (EVs) are membrane-delimited nanoparticles found in every kingdom of life and are known to mediate cell-cell communication in animal systems through the trafficking of proteins and nucleic acids. Research into plant and microbial EVs suggests that these have similar transport capacity, and moreover are able to mediate signalling not only within an organism but also between organisms, acting between plants and their microbial partners in cross-kingdom signalling. Here, we review recent research exploring the roles of these EVs, both plant and microbial, highlighting emerging trends of functional conservation between species and across kingdoms, complemented by the heterogeneity of EV subpopulations at the organism level that places EVs as powerful regulatory mechanisms in plant biotic interactions.
细胞外囊泡（EVs）是存在于每个生命王国中的膜界定纳米颗粒，已知其在动物系统中通过蛋白质和核酸的运输介导细胞间通讯。对植物和微生物细胞外囊泡的研究表明，它们具有相似的运输能力，而且不仅能够在生物体内部介导信号传导，还能在生物体之间介导信号传导，在植物与其微生物伙伴之间的跨王国信号传导中发挥作用。在这里，我们综述了最近探索这些植物和微生物细胞外囊泡作用的研究，强调了物种间和跨王国功能保守性的新趋势，同时也补充了生物体水平上细胞外囊泡亚群的异质性，这使得细胞外囊泡成为植物生物相互作用中的强大调节机制。
