Nodulation of legumes by members of the β-subclass of Proteobacteria
Members of the Leguminosae form the largest plant family on Earth, with around 18,000 species. The success of legumes can largely be attributed to their ability to form a nitrogen-fixing symbiosisExpand

Legume symbiotic nitrogen fixation by beta-proteobacteria is widespread in nature.
Following the initial discovery of two legume-nodulating Burkholderia strains (L. Moulin, A. Munive, B. Dreyfus, and C. Boivin-Masson, Nature 411:948-950, 2001), we identified as nitrogen-fixingExpand

Legumes Symbioses: Absence of Nod Genes in Photosynthetic Bradyrhizobia
Leguminous plants (such as peas and soybeans) and rhizobial soil bacteria are symbiotic partners that communicate through molecular signaling pathways, resulting in the formation of nodules on legumeExpand

Legume-nodulating betaproteobacteria: diversity, host range, and future prospects.
Rhizobia form specialized nodules on the roots of legumes (family Fabaceae) and fix nitrogen in exchange for carbon from the host plant. Although the majority of legumes form symbioses with membersExpand

Phylogenetic analyses of symbiotic nodulation genes support vertical and lateral gene co-transfer within the Bradyrhizobium genus.
Symbiotic nitrogen fixing bacteria-known as rhizobia-harbour a set of nodulation (nod) genes that control the synthesis of modified lipo-chitooligosaccharides, called Nod factors that are requiredExpand

Genetic diversity of Mimosa pudica rhizobial symbionts in soils of French Guiana: investigating the origin and diversity of Burkholderia phymatum and other beta-rhizobia.
The genetic diversity of 221 Mimosa pudica bacterial symbionts trapped from eight soils from diverse environments in French Guiana was assessed by 16S rRNA PCR-RFLP, REP-PCR fingerprints, as well asExpand

European Origin of Bradyrhizobium Populations Infecting Lupins and Serradella in Soils of Western Australia and South Africa
ABSTRACT We applied a multilocus phylogenetic approach to elucidate the origin of serradella and lupin Bradyrhizobium strains that persist in soils of Western Australia and South Africa. The selectedExpand

Burkholderia phymatum is a highly effective nitrogen-fixing symbiont of Mimosa spp. and fixes nitrogen ex planta.
* The ability of Burkholderia phymatum STM815 to effectively nodulate Mimosa spp., and to fix nitrogen ex planta, was compared with that of the known Mimosa symbiont Cupriavidus taiwanensis LMG19424.Expand

The variable part of the dnaK gene as an alternative marker for phylogenetic studies of rhizobia and related alpha Proteobacteria.
DnaK is the 70 kDa chaperone that prevents protein aggregation and supports the refolding of damaged proteins. Due to sequence conservation and its ubiquity this chaperone has been widely used inExpand

Multilocus sequence analysis of bradyrhizobia isolated from Aeschynomene species in Senegal.
This study reports the multilocus sequence analysis (MLSA) of nine house-keeping gene fragments (atpD, dnaK, glnA, glnB, gltA, gyrB, recA, rpoB and thrC) on a collection of 38 Bradyrhizobium isolatedExpand
