More than one hundred years have passed since the development of the first microbial
inoculant for plants. Nowadays, the use of microbial inoculants in agriculture is spread …

Most species in the Leguminosae (legume family) can fix atmospheric nitrogen (N2) via
symbiotic bacteria (rhizobia) in root nodules. Here, the literature on legume-rhizobia …

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 …

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 …

Rhizobial symbiosis genes are often carried on symbiotic islands or plasmids that can be
transferred (horizontal transfer) between different bacterial species. Symbiosis genes …

Bacteria currently included in Rhizobium leguminosarum are too diverse to be considered a
single species, so we can refer to this as a species complex (the Rlc). We have found 429 …

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 …

The Rhizobia are collectively comprised of gram negative soil bacteria that have the ability
to form symbiotic nitrogen-fixing root and/or stem nodules in association with leguminous …

The growing interest in a healthy lifestyle and in environmental protection is changing habits
regarding food consumption and agricultural practices. Good agricultural practice is …

Genomic evidence indicates that the Rhizobium leguminosarum species complex comprises
multiple distinct species, perhaps 18 or more. Of the five earliest genospecies (gs) to be …
