%X Rhizobia can establish a nitrogen-fixing symbiosis with plants of the #Leguminosae$ family. They elicit on their host plant the formation of new organs, called nodules, which develop on the roots. A few aquatic legumes, however, can form nodules on their stem at dormant root primordia. The stem-nodulating legumes described so far are all members of the genera #Aeschynomene$, #Sesbania$, #Neptunia$, and #Discolobium$. Their rhizobial symbionts belong to four genera already described : #Rhizobium$, #Bradyrhizobium$, #Sinorhizobium$, and #Azorhizobium$. This review summarizes our current knowledge on most aspects of stem nodulation in legumes, the infection process and nodule development, the characterization and unusual features of the associated bacteria, and the molecular genetics of nodulation. Potential use as green manure in lowland rice of these stem-nodulating legumes, giving them agronomical importance, is also discussed. (Résumé d'auteur)
