Legume specificity is encoded in rhizobial genetic elements that may be transferred among
species and genera. Dissemination (by lateral transfer) of gene assemblies dictating host …

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 …

Rhizobia are Gram-negative bacteria that can exist either as free-living bacteria or as
nitrogen-fixing symbionts inside root nodules of leguminous plants. The composition of the …

Biological species may remain distinct because of genetic isolation or ecological adaptation,
but these two aspects do not always coincide. To establish the nature of the species …

Legumes have traditionally been used in soil regeneration, owing to their capacity to
increase soil nitrogen due to biological nitrogen fixation. Recently, legumes have attracted …

Root nodule bacteria are free-living soil bacteria, belonging to diverse genera within the
Alphaproteobacteria and Betaproteobacteria, that have the capacity to form nitrogen-fixing …

Establishment of the symbiotic relationship that develops between rhizobia and their legume
hosts is contingent upon an interkingdom signal exchange. In response to host legume …

Replicon architecture in bacteria is commonly comprised of one indispensable chromosome
and several dispensable plasmids. This view has been enriched by the discovery of …

Due to the wide cultivation of bean (Phaseolus vulgaris L.), rhizobia associated with this
plant have been isolated from many different geographical regions. In order to investigate …

Rhizobium leguminosarum bv. viciae is a soil α-proteobacterium that establishes a
diazotrophic symbiosis with different legumes of the Fabeae tribe. The number of genome …
