Rhizobia are soil bacteria that can become endosymbionts, reducing atmospheric nitrogen within nodules formed on the roots of legume plants. During tissue and cell invasion, bacterial cell-surface components adapt the bacterium to survive as an endophyte without eliciting host-defence responses. The structures of many of these components have been established recently, allowing their possible roles in invasion to be defined more clearly.
根瘤菌是一种土壤细菌，它能够成为内共生体，在豆科植物根部形成的根瘤内将大气中的氮还原。在组织和细胞入侵过程中，细菌细胞表面成分使细菌能够作为内生菌存活，而不会引发宿主防御反应。最近已经确定了许多这些成分的结构，从而能够更清楚地界定它们在入侵过程中可能发挥的作用。
