mesorhizobium septentrionale sp. nov. and mesorhizobium temperatum sp. nov., isolated from astragalus adsurgens growing in the northern regions of china.	ninety-five rhizobial strains isolated from astragalus adsurgens growing in the northern regions of china were classified into three main groups, candidate species i, ii and iii, based on a polyphasic approach. comparative analysis of full-length 16s rrna gene sequences of representative strains showed that candidate species i and ii were mesorhizobium, while candidate species iii, which consisted of non-nodulating strains, was closely related to agrobacterium tumefaciens. the phylogenetic relat ...	2004	15545425
different mesorhizobium species associated with caragana carry similar symbiotic genes and have common host ranges.	fourteen strains representing 11 caragana-nodulating mesorhizobium genomic species were identified as representing mesorhizobium amorphae, mesorhizobium huakuii, mesorhizobium septentrionale and groups related to mesorhizobium plurifarium, mesorhizobium temperatum, mesorhizobium tianshanense and mesorhizobium mediterraneum by sequencing of the 16s rrna gene, 16s-23s internal transcribed spacer, partial housekeeping reca gene, and previously performed sodium dodecyl sulfate polyacrylamide gel ele ...	2008	18422620
mesorhizobium gobiense sp. nov. and mesorhizobium tarimense sp. nov., isolated from wild legumes growing in desert soils of xinjiang, china.	twenty-four mesorhizobium strains were isolated from desert soils in the xinjiang region of china and were characterized by a polyphasic approach. these strains grouped into three clusters in igs-rflp, sds-page analysis of whole-cell proteins and box-pcr analysis, corresponding to genomic species v, vi and vii as found in a previous study. the results were supported by sequencing analyses of rrs, igs, atpd and reca genes. genospecies vii was most related to mesorhizobium septentrionale, while ge ...	2008	18984702
horizontal gene transfer and recombination shape mesorhizobial populations in the gene center of the host plants astragalus luteolus and astragalus ernestii in sichuan, china.	thirty-three rhizobial strains isolated from the root nodules of astragalus luteolus and astragalus ernestii growing on the west plateau at two different altitudes in sichuan province, china, were characterized by amplified rdna restriction analysis (ardra), amplified fragment length polymorphism (aflp), and by sequencing of rrs, glna, glnii and nifh. the ardra analysis revealed considerable genomic diversity. in aflp analysis, 20 of 33 astragalus rhizobia formed three distinct clades, with othe ...	2009	19796139
tolerance of mesorhizobium type strains to different environmental stresses.	the symbiosis between rhizobia and legumes is affected by different environmental conditions. our aims were to evaluate stress tolerance of mesorhizobium species and investigate species-specific stress response mechanisms. tolerance of mesorhizobium type strains to temperature, salt and ph stress was evaluated. mesorhizobium thiogangeticum showed highest growth with 1.5% nacl and mesorhizobium ciceri at ph 5. mesorhizobium plurifarium showed higher growth at 37°c. sds-page analysis revealed chan ...	2010	21152981
genetic diversity, community structure and distribution of rhizobia in the root nodules of caragana spp. from arid and semi-arid alkaline deserts, in the north of china.	the genetic diversity of 88 caragana nodule rhizobial isolates, collected from arid and semi-arid alkaline sandy soils in the north of china, was assessed by pcr-rflp of the 16s rrna gene and the 16s-23s igs, as well as the phylogenies of housekeeping genes (atpd, glnii and reca) and symbiotic genes (nodc and nifh). of the 88 strains, 69 were placed in the genus mesorhizobium, 16 in rhizobium and 3 in bradyrhizobium. mesorhizobium amorphae, mesorhizobium septentrionale, mesorhizobium temperatum ...	2012	22463809
mesorhizobium shonense sp. nov., mesorhizobium hawassense sp. nov. and mesorhizobium abyssinicae sp. nov., isolated from root nodules of different agroforestry legume trees.	a total of 18 strains, representing members of the genus mesorhizobium, obtained from root nodules of woody legumes growing in ethiopia, have been previously shown, by multilocus sequence analysis (mlsa) of five housekeeping genes, to form three novel genospecies. in the present study, the phylogenetic relationship between representative strains of these three genospecies and the type strains of their closest phylogenetic neighbours mesorhizobium plurifarium, mesorhizobium amorphae, mesorhizobiu ...	2013	22941297
mesorhizobium waimense sp. nov. isolated from sophora longicarinata root nodules and mesorhizobium cantuariense sp. nov. isolated from sophora microphylla root nodules.	in total 14 strains of gram-stain-negative, rod-shaped bacteria were isolated from sophora longicarinata and sophora microphylla root nodules and authenticated as rhizobia on these hosts. based on the 16s rrna gene phylogeny, they were shown to belong to the genus mesorhizobium, and the strains from s. longicarinata were most closely related to mesorhizobium amorphae accc 19665t (99.8–99.9 %), mesorhizobium huakuii iam 14158t (99.8–99.9 %), mesorhizobium loti usda 3471t (99.5–99.9 %) and mesorhi ...	2015	26296780
phylogeny of symbiotic genes and the symbiotic properties of rhizobia specific to astragalus glycyphyllos l.	the phylogeny of symbiotic genes of astragalus glycyphyllos l. (liquorice milkvetch) nodule isolates was studied by comparative sequence analysis of noda, nodc, nodh and nifh loci. in all these genes phylograms, liquorice milkvetch rhizobia (closely related to bacteria of three species, i.e. mesorhizobium amorphae, mesorhizobium septentrionale and mesorhizobium ciceri) formed one clearly separate cluster suggesting the horizontal transfer of symbiotic genes from a single ancestor to the bacteria ...	2015	26496493
diversity and phylogeny of rhizobia associated with desmodium spp. in panxi, sichuan, china.	thirty-four rhizobial isolates were obtained from root nodules of four wild desmodium species growing in panxi, sichuan, china. according to the combined ardra and igs-rflp (cacai) cluster analysis, rhizobium, pararhizobium and mesorhizobium isolates outnumbered bradyrhizobium isolates. in general, the isolates representing the same species from the same site clustered together. furthermore, the four desmodium species were all nodulated by more than one rhizobial species. aflp and phenotypic ana ...	2016	26654528
genetic diversity and distribution of rhizobia associated with the medicinal legumes astragalus spp. and hedysarum polybotrys in agricultural soils.	with the increasing cultivation of medicinal legumes in agricultural fields, the rhizobia associated with these plants are facing new stresses, mainly from fertilization and irrigation. in this study, investigations on the nodulation of three cultivated medicinal legumes, astragalus mongholicus, astragalus membranaceus and hedysarum polybotrys were performed. bacterial isolates from root nodules of these legumes were subjected to genetic diversity and multilocus sequence analyses. in addition, t ...	2016	26915496
