Abstract excerpt

Rhizobia colonize legumes and reduce N2 to NH3 in root nodules. The current model is that symbiotic rhizobia bacteroids avoid assimilating this NH3. Instead, host legume cells form glutamine from NH3, and the nitrogen is returned to the bacteroid as dicarboxylates, peptides, and amino acids. In soybean cells surrounding bacteroids, glutamine also is converted to ureides. One problem for soybean cultivation is...
