Rhizobia are some of the best-studied plant microbiota. These oligotrophic
Alphaproteobacteria or Betaproteobacteria form symbioses with their legume hosts …

All plants are inhabited internally by diverse microbial communities comprising bacterial,
archaeal, fungal, and protistic taxa. These microorganisms showing endophytic lifestyles …

genera 41 III. Latitudinal variations in the distribution of nodulated legumes 44 IV …

In both managed and natural ecosystems, beneficial plant-associated bacteria play a key
role in supporting and/or increasing plant health and growth. Plant growth-promoting …

Symbiotic interactions such as the nitrogen-fixing root nodule symbiosis (RNS) have
structured ecosystems during the evolution of life. Here we aimed at reconstructing ancestral …

Legumes form a large group of plants that constitute the third largest family of angiosperms,
including near 20,000 species and 750 genera. Most of them have the ability to establish …

Microorganisms are found everywhere, and they are closely associated with plants.
Because the establishment of any plant–microbe association involves chemical …

The need for sustainable agricultural practices is revitalizing the interest in biological
nitrogen fixation and rhizobia-legumes symbioses, particularly those involving economically …

Bacterial accessory genes are genomic symbionts with an evolutionary history and future
that is different from that of their hosts. Packages of accessory genes move from strain to …

Background The metabolic capacity for nitrogen fixation is known to be present in several
prokaryotic species scattered across taxonomic groups. Experimental detection of nitrogen …
