Eukaryotes often form symbioses with microorganisms. Among these, associations between
plants and nitrogen-fixing bacteria are responsible for the nitrogen input into various …

▪ Abstract Rhizobia are soil bacteria that can engage in a symbiosis with leguminous plants
that produces nitrogen-fixing root nodules. This symbiosis is based on specific recognition of …

Specific complex interactions between soil bacteria belonging to Rhizobium, Sinorhizobium,
Mesorhizobium, Phylorhizobium, Bradyrhizobium and Azorhizobium commonly known as …

When the rhizosphere is nitrogen‐starved, legumes and rhizobia (soil bacteria) enter into a
symbiosis that enables the fixation of atmospheric dinitrogen. This implies a complex …

Covering: bacterial genome sequences to 2005 and post-genomic literature to June 2006 A
total of 223 complete bacterial genomes are analyzed, with 281 citations, for the presence of …

Sinorhizobium meliloti is an α-proteobacterium that forms agronomically important N2-fixing
root nodules in legumes. We report here the complete sequence of the largest constituent of …

Analysis of the 1,683,333-nt sequence of the pSymB megaplasmid from the symbiotic N2-
fixing bacterium Sinorhizobium meliloti revealed that the replicon has a high gene density …

Sinorhizobium meliloti is an α-proteobacterium that alternates between a free-living phase in
bulk soil or in the rhizosphere of plants and a symbiotic phase within the host plant cells …

Rhizobia are soil proteobacteria able to engage in a nitrogen-fixing symbiotic interaction
with legumes that involves the rhizobial infection of roots and the bacterial invasion of new …

The soil bacterium Sinorhizobium meliloti is capable of entering into a nitrogen-fixing
symbiosis with Medicago sativa (alfalfa). Particular low-molecular-weight forms of certain …
