Stem nodulation: diversity and occurrence in Aeschynomene and Sesbania legumes from wetlands of Madagascar
As an adaptation to flooding, few legume species have the original ability to develop nitrogen-fixing nodules on the stem. By surveying wetlands of Madagascar, we found a large occurrence and diversity of stem nodulation in Aeschynomene and Sesbania legumes. They represent opportunities to investigate different modalities of the nitrogen-fixing symbiosis in legumes.
