Diazotrophic rhizobia infect legume plants in a highly regulated manner. This infection process can be divided in three steps in which bacteria cross the root epidermis, spread through the cortex and are released inside the cells of a growing nodule primordium. The way bacteria transverse the different layers is intimately controlled by the host. However, different hosts have developed different strategies (root hair, crack-entry, intercellular) to guide the infection of bacteria. In this chapter, we review the molecular mechanisms that govern the infection of root nodules leading to the intracellular accommodation of bacteria and discuss the commonalities and differences between the different strategies in terms of distribution, architecture, and regulation.
