  • The latest bacterial genome to be completely sequenced has three separate parts and as many genes as yeast. The bacterium needs these genes for its complex life in and around its legume plant partner.

  • A gene has been isolated that controls the number of symbiotic nitrogen-fixing nodules in legumes. Its similarity to a well-characterized regulatory gene in Arabidopsis provides clues about its action.

  • The association between legumes and nitrogen-fixing bacteria requires molecular recognition to allow bacterial entry into root hairs. The discovery of a novel type of plant receptor clarifies how this happens.

  • In this Review, Tsirigotakiet al. discuss recent biochemical, structural and mechanistic insights that have been gained into the consecutive steps of the general secretory (Sec) pathway. They focus on the architecture and dynamics of SecYEG and its regulation by ribosomes and SecA, and present current models of the mechanisms and energetics of the Sec-pathway-dependent secretion process in bacteria.

  • The Sec pathway, which transports proteins across membranes, is ubiquitous and essential for viability in all three domains of life. At the core of the pathway is the translocase, a dynamic nanomachine that catalyses transmembrane crossing. This Review considers the latest data on the structure and function of the bacterial Sec translocase.
