The research findings in the field of Rhizobium-legume symbiosis reported worldwide during the years 2002 and 2003 (up to September) have been summarized. The information is presented under the various topics, viz., isolation and characterization of rhizobial strains, physiological aspects of nitrogen fixation, rhizosphere interactions and root surface signals, genomics and proteomics, plant genes involved in nodule formation, bioremediation and biocontrol, and review articles and conference reports. The postal and e-mail addresses of the concerned scientists have also been included.

During the establishment of the symbiosis with legume plants, rhizobia are exposed to hostile physical and chemical microenvironments to which adaptations are required. Stress response proteins including small heat shock proteins (sHSPs) were previously shown to be differentially regulated in bacteroids induced by bv. viciae UPM791 in different hosts.

Prokaryotes and eukaryotes secrete extracellular vesicles (EVs) into the surrounding milieu to preserve and transport elevated concentrations of biomolecules across long distances. EVs encapsulate metabolites, DNA, RNA, and proteins, whose abundance and composition fluctuate depending on environmental cues. EVs are involved in eukaryote-to-prokaryote communication owing to their ability to navigate different ecological niches and exchange molecular cargo between the two domains.

The emergence of commensalism and mutualism often derives from ancestral parasitism. However, in the case of rhizobium-legume interactions, bacterial strains displaying both pathogenic and nodulation features on a single host have not been described yet. Here, we isolated such a bacterium from Medicago nodules.

Hydrogen peroxide (HO) in plants is produced in relatively large amounts and plays a universal role in plant defense and physiological responses, including the regulation of growth and development. In the -legume symbiosis, hydrogen peroxide plays an important signaling role throughout the development of this interaction. In the functioning nodule, HO has been shown to be involved in bacterial differentiation into the symbiotic form and in nodule senescence.

To successfully colonize legume root nodules, rhizobia must effectively evade host-generated reactive oxygen species (ROS). LsrB, a redox regulator from , is essential for symbiosis with alfalfa (). The three cysteine residues in LsrB's substrate domain play distinct roles in activating downstream redox genes.
