是一种植物病原体,它将自己的一段DNA转移到寄主植物中,引起冠瘿病。感染过程需要感染细菌与宿主组织密切接触。瘤胃芽胞杆菌能有效附着于植物组织和非生物表面,并能在定植部位形成复杂的生物膜。主要的附着方式是通过与表面接触的单极。几种不同的附属物、黏附素和黏附剂在附着过程中发挥作用,并促进从自由游动到无根生长的过渡。这种极性表面的相互作用反映了肿瘤分枝杆菌中更基本的细胞不对称,这种不对称影响并与其附着的生活方式一致。
is a plant pathogen that transfers a segment of its own DNA into host plants to cause Crown Gall disease. The infection process requires intimate contact between the infecting bacteria and the host tissue. A. tumefaciens attaches efficiently to plant tissues and to abiotic surfaces, and can establish complex biofilms at colonization sites. The dominant mode of attachment is via a single pole in contact with the surface. Several different appendages, adhesins and adhesives play roles during attachment, and foster the transition from free-swimming to sessile growth. This polar surface interaction reflects a more fundamental cellular asymmetry in A. tumefaciens that influences and is congruent with its attached lifestyle.
