The species Mesorhizobim loti was isolated from nodules of Lotus corniculatus and its type strain deposited in several collections. Some of these type strains, such as those deposited in the USDA and ATCC collections before 1990, are not coincident with the original strain, NZP 2213T, deposited in the NZP culture collection. The analysis of the 16S rRNA gene showed that strains USDA 3471T and ATCC 33669T formed independent branches from that occupied by Mesorhizobium loti NZP 2213T and related… 
Reclassification of strains MAFF 303099T and R7A into Mesorhizobiumjaponicum sp. nov.
TLDR
The analysis of recA and glnII gene sequeces showed that M. jarvisii ATCC 33669T and M. huakuii USDA 4779T are the most closely related strains to MAFF 303099T and R7A, with similarity values suggesting that these two strains belong to a different species for which MAFF 29417T is selected as the type strain.
Mesorhizobium intechi sp. nov. isolated from nodules of Lotus tenuis in soils of the Flooding Pampa, Argentina.
TLDR
Three symbiotic nitrogen-fixing bacteria isolated from root nodules of Lotus tenuis in lowland soils of the Flooding Pampa (Argentina), previously classified as members of the Mesorhizobium genus, were characterized and could be considered to represent a novel species of that genus.
Mesorhizobium olivaresii sp. nov. isolated from Lotus corniculatus nodules.
TLDR
Results indicated that the L. corniculatus strains belong to a new species of genus Mesorhizobium which was confirmed by DNA-DNA hybridization and phenotypic characterization.
Mesorhizobium helmanticense sp. nov., isolated from Lotus corniculatus nodules.
TLDR
The results of phenotypic characterization support that the L. corniculatus nodulating strains analysed in this work belong to a novel species of the genus Mesorhizobium, and the type strain is CSLC115NT (= LMG 29734T=CECT 9168T).
Mesorhizobium carmichaelinearum sp. nov., isolated from Carmichaelineae spp. root nodules.
TLDR
Five strains of Gram-stain-negative, rod-shaped bacteria isolated from Carmichaelia and Montigena root nodules are considered to represent a novel species, for which the name Mesorhizobium carmichaelinearum sp.
Reclassification of the taxonomic status of SEMIA3007 isolated in Mexico B-11A Mex as Rhizobium leguminosarum bv. viceae by bioinformatic tools
TLDR
The results of the phylogenetic analysis clearly show SEMIA3007 is part of the Mesorhizobium group and suggest a reclassification is warranted.
Mesorhizobium zhangyense sp. nov., isolated from wild Thermopsis lanceolate in northwestern China
TLDR
Based on the phenotypic, chemotaxonomic and phylogenetic properties, strain 23-3-2T represents a novel species of the genus Mesorhizobium, for which the name MesorHizobia zhangyense sp.
The high diversity of Lotus corniculatus endosymbionts in soils of northwest Spain
TLDR
Great phylogenetic diversity of strains nodulating L. corniculatus nodulating strains isolated in Europe, America and Asia is revealed, allowing us to predict that even more diversity will be discovered as further ecosystems are investigated.
Mesorhizobium norvegicum sp. nov., a rhizobium isolated from a Lotus corniculatus root nodule in Norway.
TLDR
Phylogenetic analyses based on the 16S rRNA gene and housekeeping gene alignments placed this strain within the genus Mesorhizobium, and pairwise genome-wide average nucleotide identity values supported that strain 10.2.2T represents a new species.
Symbiosis islands of Loteae-nodulating Mesorhizobium comprise three radiating lineages with concordant nod gene complements and nodulation host-range groupings
TLDR
Bioinformatic comparison with previously sequenced mesorhizobium genomes indicated host range was not predicted by MesorhZobium genospecies but rather by the evolutionary relationship between ICESym symbiotic regions, and three radiating lineages of Loteae ICESyms were identified.

Mesorhizobial strains nodulating Anagyris latifolia and Lotus berthelotii in Tamadaya ravine (Tenerife, Canary Islands) are two symbiovars of the same species, Mesorhizobium tamadayense sp. nov.
TLDR
DNA-DNA hybridisation homology percentages were lower than 30% compared to type strains of the closest related species, and supported the phylogenetic data, which confirmed that the isolates represented a novel species for which the name Mesorhizobium tamadayense sp.
Bradyrhizobium canariense sp. nov., an acid-tolerant endosymbiont that nodulates endemic genistoid legumes (Papilionoideae: Genisteae) from the Canary Islands, along with Bradyrhizobium japonicum bv. genistearum, Bradyrhizobium genospecies alpha and Bradyrhizobium genospecies beta.
TLDR
In addition to the currently described species, this phylogeny uncovered the novel Bradyrhizobium genospecies alpha and beta and the photosynthetic strains as independent evolutionary lineages.
Phylogenies of atpD and recA support the small subunit rRNA-based classification of rhizobia.
TLDR
Part of the atpD and recA genes have been sequenced for 25 type strains within the alpha-Proteobacteria, showing good support for a Rhizobium clade that includes Agrobacterium tumefaciens, and the very close relationship between Agrobacteria rhizogenes and RhizOBium tropici is confirmed.
Proposal for rejection of Agrobacterium tumefaciens and revised descriptions for the genus Agrobacterium and for Agrobacterium radiobacter and Agrobacterium rhizogenes.
TLDR
A phylogenetic analysis showed that the 15 strains of Agrobacterium and Rhizobium species formed a compact phylogenetic cluster clearly separated from the other members of the alpha subclass of the Proteobacteria, and two species should be established for the two biovars.
A phylogenetic analysis of the genus Nocardia with 16S rRNA gene sequences.
TLDR
The results of isoprenoid quinone analyses provided evidence that nocardiae can be distinguished from all other actinomycete taxa on the basis of their characteristic menaquinone profiles.
Differences between subcultures of the Mesorhizobium loti type strain from different culture collections.
TLDR
The results indicate that maintenance procedures necessary for long-term preservation by freeze-drying can cause subcultures of the same original strain to undergo changes, effectively leading to different fingerprints even though 16S rDNA sequences remain identical.
Phylogenetic analysis of the family Rhizobiaceae and related bacteria by sequencing of 16S rRNA gene using PCR and DNA sequencer.
TLDR
The family Rhizobiaceae should be redefined including the above-mentioned genera despite the ability for plant association and nitrogen fixation.
Phylogenetic analysis of rhizobia and agrobacteria based on 16S rRNA gene sequences.
TLDR
The genus and species definitions of these organisms are in need of revision because they are found to be phylogenetically heterogeneous, and several subgroupings in which Rhizobium and Agrobacterium species were intermixed were evident.
Bacterial Associations with Legumes
TLDR
This review presents an overview of the associations of bacteria with legumes, the current available knowledge on the phylogenetic diversity of both Rhizobia and endophytic bacteria inhabiting root nodules, and the symbiotic features used to define symbiovars in rhizobia.
DNA-DNA hybridization study of Bradyrhizobium strains.
TLDR
Results indicated that the genus Bradyrhizobium consists of at least 11 genospecies, I to XI, which formed four subgeneric groups that were more closely related to each other (>40% DNA hybridization) than to other genos pecies.
