The root microbiome refers to the community of microbes living in association with a plant's roots, and includes mutualists, pathogens, and commensals. Here we focus on recent advances in the study of root commensal community which is the major research object of microbiome-related researches. With the rapid development of new technologies, plant–commensal interactions can be explored with unprecedented breadth and depth. Both the soil environment and the host plant drive commensal community assembly. The bulk soil is the seed bank of potential commensals, and plants use root exudates and immune responses to build healthy microbial communities from the available microbes. The plant microbiome extends the functional system of plants by participating in a variety of processes, including nutrient absorption, growth promotion, and resistance to biotic and abiotic stresses. Plants and their microbiomes have evolved adaptation strategies over time. However, there is still a huge gap in our understanding of the regulatory mechanisms of plant–commensal interactions. In this review, we summarize recent research on the assembly of root microbial communities and the effects of these communities on plant growth and development, and look at the prospects for promoting sustainable agricultural development through the study of the root microbiome.

根微生物组：群落组装及其对植物适应性的贡献

根微生物组是指与植物根部相关的微生物群落，包括共生体、病原体和共生体。在这里，我们重点关注根共生群落研究的最新进展，这是微生物组相关研究的主要研究对象。随着新技术的快速发展，植物与共生的相互作用可以以前所未有的广度和深度进行探索。土壤环境和寄主植物都驱动共生群落组装。大块土壤是潜在共生菌的种子库，植物利用根系分泌物和免疫反应从可用微生物中构建健康的微生物群落。植物微生物组通过参与多种过程来扩展植物的功能系统，包括养分吸收、生长促进、以及对生物和非生物胁迫的抵抗力。随着时间的推移，植物及其微生物组已经进化出适应策略。然而，我们对植物-共生相互作用的调控机制的理解仍然存在巨大差距。在这篇综述中，我们总结了近期关于根系微生物群落组装以及这些群落对植物生长发育影响的研究，并展望了通过根系微生物组研究促进可持续农业发展的前景。
