%X Crop production currently relies on the widespread use of agrochemicals to ensure food security. This practice is considered unsustainable, yet has no viable alternative at present. The plant microbiota can fulfil various functions for its host, some of which could be the basis for developing sustainable protection and fertilization strategies for plants without relying on chemicals. To harness such functions, a detailed understanding of plant‒microbe and microbe‒microbe interactions is necessary. Among interactions within the plant microbiota, those between bacteria are the most common ones; they are not only of ecological importance but also essential for maintaining the health and productivity of the host plants. This review focuses on recent literature in this field and highlights various consequences of bacteria‒bacteria interactions under different agricultural settings. In addition, the molecular and genetic backgrounds of bacteria that facilitate such interactions are emphasized. Representative examples of commonly found bacterial metabolites with bioactive properties, as well as their modes of action, are given. Integrating our understanding of various binary interactions into complex models that encompass the entire microbiota will benefit future developments in agriculture and beyond, which could be further facilitated by artificial intelligence-based technologies.<BR>化学农药防治是当前农业生产中防治作物病虫害最主要的措施，对粮食安全生产起到至关重要的作用。化学农药的不合理使用会导致有害生物抗药性和环境污染等问题，因此利用有益农业微生物资源控制作物有害生物被认为是替代化学防治的可持续举措之一。植物微生物群落对宿主植物的生长发育等具有重要作用，其中部分微生物具有开发为微生物农药和肥料的潜力。全面解析微生物群落中细菌之间的相互作用及其生态功能，对合理利用微生物菌落的功能来维持植物的健康和生产力至关重要。本综述重点关注微生物群落中细菌-细菌之间互作机理及其在不同环境下对作物发育与健康的影响，并强调如何通过调控这种互作改善作物生长环境，以及小分子物质和信号调控通路在细菌-细菌相互作用中的关键作用。本文列举了具有生物活性的细菌代谢产物介导细菌-细菌互作的典型案例及其互作机制。未来需要充分利用人工智能等先进技术，将微生物群落中各种二元互作方式整合到整个微生物组的复杂模型中，以进一步了解微生物群落中各组分间的互作机理，为更好地利用农业有益微生物资源解决作物病虫害等问题提供解决方案。.
