Zusammenfassung:	The focus of research on signalling in Rhizobium–legume interactions has moved from understanding the structure and synthesis of rhizobially made Nod factors, towards an analysis of how they function in plants. Nod-factor-induced changes in ion fluxes across membranes, followed by establishment of an oscillation of intracellular Ca 2+ concentration, point to the involvement of a receptor-mediated signal transduction pathway. Progress towards the identification of components in this pathway is being made by identifying Nod-factor binding proteins, isolating plant mutants that are defective in signalling and analysing plant responses to Nod factors.
