Abstract
Recent work indicating that there may be a flow of fixed nitrogen to Rhizobium bacteroids is discussed in light of a hypothesis that such a flow may be important to nodule function. Evidence that nitrogen is transported to the microsymbiont includes analysis of auxotrophic mutants, consideration of proline metabolism in nodules, and the finding of unusual amino compounds within nodules that can specifically support bacteria growth. We describe experiments that implicate an NAD dependent glutamate dehydrogenase in glutamate catabolism by free living bacteria.
