  abstract = {{L}egumes have the ability to establish a nitrogen-fixing symbiosis with soil rhizobia that they house in specific organs, the nodules. {I}n most rhizobium-legume interactions, nodulation occurs on the root. {H}owever, certain tropical legumes growing in wetlands possess a unique trait: the capacity to form rhizobia-harbouring nodules on the stem. {D}espite the originality of the stem nodulation process, its occurrence and diversity in waterlogging-tolerant legumes remains underexplored, impeding a comprehensive analysis of its genetics and biology. {H}ere, we aimed at filling this gap by surveying stem nodulation in legume species-rich wetlands of {M}adagascar. {S}tem nodulation was readily observed in eight hydrophytic species of the legume genera, {A}eschynomene and {S}esbania, for which significant variations in stem nodule density and morphology was documented. {A}mong these species, {A}. evenia, which is used as genetic model to study the rhizobial symbiosis, was found to be frequently stem-nodulated. {T}wo other {A}eschynomene species, {A}. cristata and {A}. uniflora, were evidenced to display a profuse stem-nodulation as occurs in {S}. rostrata. {T}hese findings extend our knowledge on legumes species that are endowed with stem nodulation and further indicate that {A}. evenia, {A}. cristata, {A}. uniflora and {S}. rostrata are of special interest for the study of stem nodulation. {A}s such, these legume species represent opportunities to investigate different modalities of the nitrogen-fixing symbiosis and this knowledge could provide cues for the engineering of nitrogen-fixation in non-legume crops.},
