Plant immune receptors perceive microbial molecules and initiate an array of biochemical responses that are effective against most invaders. The role of the plant immune system in detecting and controlling pathogenic microorganism has been well described. In contrast, much less is known about plant immunity in the context of the wealth of commensals that inhabit plants. Recent research indicates that, just like pathogens, commensals in the plant microbiome can suppress or evade host immune responses. Moreover, the plant immune system has an active role in microbiome assembly and controls microbial homeostasis in response to environmental variation. We propose that the plant immune system shapes the microbiome, and that the microbiome expands plant immunity and acts as an additional layer of defense against pathogenic organisms.

病原体之外：微生物群与植物免疫系统的相互作用。

植物免疫受体感知微生物分子并启动一系列对大多数入侵者有效的生化反应。已经很好地描述了植物免疫系统在检测和控制病原微生物中的作用。相反，关于植物免疫的知识在丰富的植物栖息地背景下知之甚少。最近的研究表明，就像病原体一样，植物微生物组中的共鸣可以抑制或逃避宿主的免疫反应。此外，植物免疫系统在微生物组装配中具有积极作用，并响应于环境变化而控制微生物稳态。我们建议植物免疫系统塑造微生物组，并且微生物组扩大植物免疫力并充当抵抗病原生物的附加防御层。
