TLDR
A tropical legume species with aerial nodules, Sesbania 2.1.1 is reported here on, which grows in flooded soils and has two types of nodules: root nodules like other legumes, and stem nodules.Abstract:
The only recorded instances of legume, species with aerial nodules are for Neptunia oleracea [ 11 and Aeschynomene indica [2,3 J . This latter, which grows in flooded soils, has two types of nodules: root nodules like other legumes, and stem nodules. Stem , nodules of A. indica usually are distributed sparsely along the lower stem and look more like small swellings than conventional Rhizobium nodules. We report here on a tropical legume, Sesbania 2.1. Techniques for structural studiesread more

Characterization of Azorhizobium caulinodans gen. nov., sp. nov., a stem-nodulating nitrogen-fixing bacterium isolated from Sesbania rostrata
TL;DR: The Sesbania stem- and root-nodulating bacterial strains are genuine rhizobia and constitute a separate rRNA subbranch on the Rhodopseudomonas palustris rRNA branch in rRNA superfamily IV.

Biodiversity of endophytic bacteria which colonize red clover nodules, roots, stems and foliage and their influence on host growth
TL;DR: In root bacterization experiments, species of nodule bacteria promoted growth of red clover more often when applied in combination with R. leguminosarum BV trifolii than when applied singly, considered further evidence of the beneficial allelopathic side effect of strain competition for the same ecological niche.

Manipulation of rhizobia microflora for improving legume productivity and soil fertility: a critical assessment
TL;DR: This paper considers ways and means by which populations of root-nodule bacteria can be manipulated ecologically, agronomically, edaphically and genetically to improve legume productivity and, as a consequence, soil fertility.

TL;DR: The discovery that photosynthetic Bradyrhizobium strains, which are usually known to induce nitrogen-fixing nodules on stems of the legume Aeschynomene, are also natural true endophytes of the primitive rice O. breviligulatacould significantly enhance cultivated rice production is found.
