Abstract

During the Rhizobium-legume symbiosis, bacteria enter the cells of host plants and differentiate into nitrogen-fixing bacteroids. Recent mutant screens and expression studies have revealed bacterial genes involved in the developmental pathway and demonstrate how the genetic requirements can vary from one host-microbe system to another. Whether bacteroids are terminally differentiated cells is an ongoing debate and new experimental systems are required to address this issue.
