Plants support a diverse array of bacteria, including parasites, mutualists, and commensals on and around their roots, in the vasculature, and on aerial tissues. These microbes have a profound influence on plant health and productivity. Bacteria physically interact with surfaces to form complex multicellular and often multispecies assemblies, including biofilms and smaller aggregates. There is growing appreciation that the intensity, duration, and outcome of plant-microbe interactions are significantly influenced by the conformation of adherent microbial populations. Biofilms on different tissues have unique properties, reflecting the prevailing conditions at those sites. Attachment is required for biofilm formation, and bacteria interact with plant tissues through adhesins including polysaccharides and surface proteins, with initial contact often mediated by active motility. Recognition between lectins and their cognate carbohydrates is a common means of specificity. Biofilm development and the resulting intimate interactions with plants often require cell-cell communication between colonizing bacteria.

由植物相关细菌形成的生物膜。

植物在其根部，周围，脉管系统和气管组织中支持各种各样的细菌，包括寄生虫，共生细菌和共生细菌。这些微生物对植物健康和生产力有深远的影响。细菌与表面物理相互作用，形成复杂的多细胞和通常为多物种的组件，包括生物膜和较小的聚集体。人们越来越认识到，植物-微生物相互作用的强度，持续时间和结果受粘附的微生物种群的构象影响很大。不同组织上的生物膜具有独特的特性，反映了这些部位的普遍状况。生物膜形成需要附着，细菌通过黏附素（包括多糖和表面蛋白）与植物组织相互作用，最初的接触通常是由主动运动介导的。凝集素及其同源碳水化合物之间的识别是特异性的常见手段。生物膜的发展及其与植物的紧密相互作用通常需要定殖细菌之间的细胞间通讯。
