Often, plant-pathogenic microbe interactions are discussed in a host-microbe two-component system, however very little is known about how the diversity of rhizospheric microbes that associate with plants affect host performance against pathogens. There are various studies, which specially direct the importance of induced systemic defense (ISR) response in plants interacting with beneficial rhizobacteria, yet we don't know how rhizobacterial associations modulate plant physiology. In here, we highlight the many dimensions within which plant roots associate with beneficial microbes by regulating aboveground physiology. We review approaches to study the causes and consequences of plant root association with beneficial microbes on aboveground plant-pathogen interactions. The review provides the foundations for future investigations into the impact of the root beneficial microbial associations on plant performance and innate defense responses.
通常，植物病原微生物的相互作用是在一个宿主-微生物两组件系统中讨论的，然而，对于与植物相关的根际微生物多样性如何影响宿主对病原体的抗性，人们知之甚少。有许多研究专门指出了植物与有益根细菌相互作用时诱导系统抗性（ISR）反应的重要性，但我们不知道根细菌的相互作用如何调节植物的生理。在这里，我们通过调节地上部分的生理来强调植物根系与有益微生物相互作用的许多方面。我们综述了研究植物根系与有益微生物相互作用对地上部植物-病原体相互作用的原因和后果的方法。该综述为未来研究根有益微生物对植物性能和先天防御反应的影响奠定了基础。
