The genetic diversity of root nodulating bacteria isolated from Retama sphaerocarpa was studied using BOX-A1R PCR and phylogenetic analysis of the 16S rRNA region, as well as the housekeeping genes atpD, glnII and recA. A total of 193 isolates were obtained from eight different sites with different soil and environmental conditions in the Iberian Peninsula. These isolates corresponded to 31 different strains that successfully nodulated R. sphaerocarpa seedlings in reinoculation trials. About… Expand
Diverse Bacteria Affiliated with the Genera Microvirga, Phyllobacterium, and Bradyrhizobium Nodulate Lupinus micranthus Growing in Soils of Northern Tunisia
TLDR
These data indicate a remarkable diversity of L. micranthus root nodule symbionts in northern Tunisia, including strains from the Bradyrhizobiaceae, Methylobacteriaceae, and Phyllobacteria families, in contrast with those of the rhizobial populations nodulating lupines in the Old World. Expand
Bradyrhizobium sp. sv. retamae nodulates Retama monosperma grown in a lead and zinc mine tailings in Eastern Morocco.
TLDR
The phylogeny of the nodA and nodC nodulation genes as well as the nifH gene of the three strains showed that they belong to the symbiovar retamae of the genus Bradyrhizobium, and could be considered for use as inoculum for Retama plants before use in phytoremediation experiments. Expand
Identification of symbiotic nitrogen-fixing bacteria from three African leguminous trees in Gorongosa National Park.
TLDR
This study examined the identity and diversity of symbiotic-nitrogen fixing bacteria associated with Acacia xanthophloea, Faidherbia albida and Albizia versicolor in the Gorongosa National Park (GNP) in Mozambique and found a clear delimitation in the rhizobial communities and soils related to these species. Expand
Disparate origins of Bradyrhizobium symbionts for invasive populations of Cytisus scoparius (Leguminosae) in North America.
TLDR
Bayesian phylogenetic analysis showed that North American C. scoparius symbionts had highly heterogeneous ancestry, and it appears that bacteria ancestrally associated with other North American legumes have evolved to utilize C.Scoparius by acquiring SI-region genes from European C. Scoparius. Expand
Characterization of Retama sphaerocarpa microsymbionts in Zaida lead mine tailings in the Moroccan middle Atlas.
In the Moroccan Middle Atlas, the tailings rich in lead and other metal residues, in the abandoned Zaida mining district, represent a real threat to environment and the neighboring villages'Expand
The Spread of Bradyrhizobium Lineages Across Host Legume Clades: from Abarema to Zygia

  • Microbial Ecology
  • 2014
TLDR
Bradyrhizobium spread across the major legume lineages early in its evolution, with only a few derived clades subsequently developing a narrower pattern of host use, which suggests that recent host switching has occurred most often within particular subgroups of legumes. Expand
Phylogeny and Phylogeography of Rhizobial Symbionts Nodulating Legumes of the Tribe Genisteae
TLDR
The legume tribe Genisteae comprises 618, predominantly temperate species, showing an amphi-Atlantic distribution that was caused by several long-distance dispersal events, and Bradyrhizobium predominates among rhizobia nodulating GenisteAE legumes. Expand
Preliminary characterization of slow growing rhizobial strains isolated from Retama monosperma (L.) Boiss. root nodules from Northwest coast of Algeria
TLDR
Results of this study showed that all strains had a very slow growth rate in yeast malt (YM) agar medium, forming colonies less than 1 mm in diameter after seven days incubation. Expand
Nodulation of Retama monosperma by Ensifer aridi in an Abandonned Lead Mine Soils in Eastern Morocco
TLDR
The nitrogen-fixing leguminous shrub Retama monosperma is proposed, as a model plant to use for phytostabilization experimentations, to prevent the movement of minerals to the nearby villages and limit the damages to the environment and health. Expand
Specificity in Legume-Rhizobia Symbioses
TLDR
Strain-specific legume rhizobia symbioses can develop in particular habitats and are likely to be at least in part related to the relative occurrence of the potential symbionts in soils of the different regions. Expand

Genetic diversity of rhizobia associated with indigenous legumes in different regions of Flanders (Belgium)
TLDR
Most of the legumes harboured more than one rhizobial endosymbiont in their root nodules indicating the importance of including sufficient isolates per plant in diversity studies, and the correlation of symbiosis genes with certain bacterial genera and less with the host plant. Expand
Rhizobial hitchhikers from Down Under: invasional meltdown in a plant-bacteria mutualism?
TLDR
Seven isolates obtained in this study define a new distinctive nifD group of Bradyrhizobium from western and Mediterranean Europe, which could constitute the first report of an invasional meltdown documented for a plant–bacteria mutualism. Expand

Retama species growing in different ecological-climatic areas of northeastern Algeria have a narrow range of rhizobia that form a novel phylogenetic clade within the Bradyrhizobium genus.
TLDR
Convergent results showed that the Retama nodule isolates from the northeast of Algeria formed a single evolutionary lineage, which was well differentiated from the currently named species or well-delineated unnamed genospecies of bradyrhizobia. Expand

Phylogeny and taxonomy of a diverse collection of Bradyrhizobium strains based on multilocus sequence analysis of the 16S rRNA gene, ITS region and glnII, recA, atpD and dnaK genes.
TLDR
The results confirm that MLSA is a rapid and reliable way of providing information on phylogenetic relationships and of identifying rhizobial strains potentially representative of novel species. Expand
At least five rhizobial species nodulate Phaseolus vulgaris in a Spanish soil
TLDR
It is indicated that more than five bacterial species compose this rhizobial population, as almost identical 16S rDNA alleles were identified in isolates belonging to deeply divergent multilocus enzyme electrophoresis lineages. Expand
Stress tolerance, genetic analysis and symbiotic properties of root-nodulating bacteria isolated from Mediterranean leguminous shrubs in Central Spain
TLDR
The results suggested that native rhizobia could be suitable candidates as biofertilizers and/or inoculants of leguminous shrubs with restoration or revegetation purposes in Mediterranean areas. Expand
Molecular diversity of native bradyrhizobia isolated from lima bean (Phaseolus lunatus L.) in Peru.
TLDR
Two groups with differences in growth rate were found among the isolates and their differentiation as two divergent bradyrhizobial lineages was supported by PCR-RFLP of the rpoB gene and sequence analysis of the 16S rDNA and dnaK genes. Expand
Endosymbiotic bacteria nodulating a new endemic lupine Lupinus mariae-josephi from alkaline soils in Eastern Spain represent a new lineage within the Bradyrhizobium genus.
TLDR
Phylogenetic analysis based on nodC symbiotic gene sequences showed that L. mariae-josephi bacteria constituted a new symbiotic lineage distant from those previously defined in the genus Bradyrhizobium, and all the endosymbiotic bacteria isolated from other Lupinus species of the Iberian Peninsula were related to strains of the B. canariense or B. japonicum lineages.
