Abstract

The co-existence of plants and microorganisms throughout their evolution resulted in an intertwined ecological network that serves as the basis for the functioning of today’s terrestrial ecosystems. The interactions between plants, bacteria, and fungi are often multipartite and occur both within and among kingdoms. Apart from the textbook examples of tight mutualistic associations such as root nodule symbiosis or mycorrhizas, there are also looser interactions, e.g., those between plants and plant growth-promoting bacteria and fungi. Additionally, plants are also targets of microbial pathogens. Thus, intricate mechanisms of how plants and microorganisms recognize each other have evolved, mediated by chemical signals resulting in a differential gene expression and, eventually, a physiological response. This paper aims to review the molecular basis of such signaling, the apparatus of signal sensing and transduction in bacteria and plants are outlined and exemplified. Moreover, examples of recent discoveries in the field of plant–microbe signaling are presented, i.e., quorum quenching and the involvement of small RNAs. Last but not least, suggestions are provided for the potential exploitation of plant–microbe communication networks for human benefit, e.g., in the field of sustainable agriculture, aiming at crop growth promotion and protection against pathogens.

地下有知:植物与土壤微生物之间相互联系的分子基础
植物和微生物在整个进化过程中共存,形成了一个相互交织的生态网络,为当今陆地生态系统的运作奠定了基础。植物、细菌和真菌之间的相互作用往往是多方的,既发生在植物界内部,也发生在植物界之间。除了根瘤共生或菌根等教科书上列举的紧密互惠关系外,植物与促进植物生长的细菌和真菌之间也存在松散的相互作用。此外,植物也是微生物病原体的攻击目标。因此,植物和微生物相互识别的机制错综复杂,通过化学信号的介导,导致不同的基因表达,最终产生生理反应。本文旨在回顾这种信号传递的分子基础,概述并举例说明细菌和植物的信号感应和转导装置。此外,本文还举例说明了植物-微生物信号传导领域的最新发现,即法定量淬灭和小核糖核酸的参与。最后但并非最不重要的一点是,本文就如何利用植物-微生物通讯网络为人类造福提出了建议,例如在可持续农业领域,旨在促进作物生长和抵御病原体。

期刊介绍: Phytochemistry Reviews is the sole review journal encompassing all facets of phytochemistry. It publishes peer-reviewed papers in six issues annually, including topical issues often stemming from meetings organized by the Phytochemical Society of Europe. Additionally, the journal welcomes original review papers that contribute to advancing knowledge in various aspects of plant chemistry, function, biosynthesis, effects on plant and animal physiology, pathology, and their application in agriculture and industry. Invited meeting papers are supplemented with additional review papers, providing a comprehensive overview of the current status across all areas of phytochemistry.
