title: Carbohydrate determinants of Rhizobium-legume symbioses.
abstract: Rhizobium is a genus of symbiotic nitrogen-fixing soil bacteria that induces the formation of root nodules on leguminous plants and, as such, has been the subject of considerable research attention. Much of this work was initiated in response to the question 'how does recognition occur between free living rhizobial bacteria in the soil and potential host legumes?' The answer to this question has been shown to involve both cell-surface carbohydrates on the external face of the bacteria and secreted extracellular signal oligosaccharides. This review will focus on the structure, function, and biosynthesis of two of these components--the host-specific nodule-promoting signals known as Nod(ulation) factors and the rhizobial lipopolysaccharides.
