Plants harbor a complex immune system to fight off invaders and prevent diseases. For decades, the interactions between plants and pathogens have been investigated primarily through the lens of binary interactions, largely neglecting the diversity of microbes that naturally inhabit plant tissues. Recent research, however, demonstrates that resident microbes are more than mere spectators. Instead, the plant microbiome extends host immune function and influences the outcome of a pathogen infection. Both plants and the interacting microbes produce a large diversity of metabolites that form an intricate chemical network of nutrients, signals, and antimicrobial molecules. In this review, we discuss the involvement of the plant microbiome in disease development, focusing on the biochemical conversation that occurs between plants and their associated microbiota before, during and after infection. We also highlight outstanding questions and possible directions for future research.
植物拥有一套复杂的免疫系统来抵御入侵者并预防疾病。几十年来，植物与病原体之间的相互作用主要是通过二元相互作用的视角进行研究的，很大程度上忽略了自然栖息在植物组织中的微生物的多样性。然而，最近的研究表明，常驻微生物不仅仅是旁观者。相反，植物微生物群扩展了宿主的免疫功能，并影响病原体感染的结果。植物和相互作用的微生物都会产生种类繁多的代谢产物，这些代谢产物形成了一个由营养物质、信号分子和抗菌分子组成的复杂化学网络。在这篇综述中，我们讨论了植物微生物群在疾病发展中的作用，重点关注感染前、感染期间和感染后植物与其相关微生物群之间发生的生化交流。我们还强调了悬而未决的问题以及未来研究可能的方向。
