The attachment of bacteria to roots constitutes the first physical step in many plant-microbe interactions. These interactions exert both positive and negative influences on agricultural systems depending on whether a growth-promoting, symbiotic or pathogenic relationship transpires. A common biphasic mechanism of root attachment exists across agriculturally important microbial species, including Rhizobium, Agrobacterium, Pseudomonas, Azospirillum and Salmonella. Attachment studies have revealed how plant-microbe interactions develop, and how to manipulate these relationships for agricultural benefit. Here, we review our current understanding of the molecular mechanisms governing plant-microbe root attachment and draw together a common biphasic model.
细菌与根的附着构成了许多植物-微生物相互作用的第一步。这些相互作用对农业系统既有积极影响，也有消极影响，具体取决于是否存在促进生长、共生或致病的关系。在农业上重要的微生物物种中，包括根瘤菌、农杆菌、假单胞菌、固氮螺菌和沙门氏菌，存在一种常见的双相附着机制。附着研究揭示了植物-微生物相互作用的发展方式，以及如何操纵这些关系以造福农业。在这里，我们回顾了我们对控制植物-微生物根附着的分子机制的理解，并提出了一个共同的双相模型。
