The microbiomes of rhizocompartments (nodule endophytes, root rhizosphere and zone) in soya bean alfalfa were analysed using high-throughput sequencing to investigate the interactions among legume species, microorganisms soil types. A clear hierarchical filtration microbiota by plants was observed four - nodule endosphere, zone as demonstrated significant variations composition microbial community different compartments. communities largely influenced type, endophytes primarily determined...
As the putative center of origin for soybean and second largest region production in China, North China Plain covers temperate subtropical regions with diverse soil characteristics. However, rhizobia this plain have not been sufficiently studied. To investigate biodiversity biogeography plain, a total 309 isolates symbiotic bacteria from nodules collected 16 sampling sites were studied by molecular characterization. These classified into 10 genospecies belonging to genera Sinorhizobium...
A total of 115 endophytic bacteria were isolated from root nodules the wild legume Sphaerophysa salsula grown in two ecological regions Loess Plateau China. The genetic diversity and phylogeny strains revealed by restriction fragment length polymorphism sequencing 16S rRNA gene enterobacterial repetitive intergenic consensus-PCR. Their symbiotic capacity was checked nodulation tests analysis nifH sequence. This is first systematic study on associated with S. nodules. Fifty found belonging to...
Abstract As a global problem, environmental pollution is an important factor to shape the microbial communities. The elucidation of succession communities in response pollutants essential for developing bioremediation procedures. In present study, ten batches soil-enrichment subcultures were subjected four treatments: phenanthrene, n-octadecane, phenanthrene + or n-octadecane CdCl 2 . Forty pollutant-degrading consortia, corresponding each batch treatments obtained. High-throughput...
Bacteria currently included in Rhizobium leguminosarum are too diverse to be considered a single species, so we can refer this as species complex (the Rlc). We have found 429 publicly available genome sequences that fall within the Rlc and these show is distinct entity, well separated from other genus. Its sister taxon R. anhuiense. constructed phylogeny based on concatenated of 120 universal (core) genes, calculated pairwise average nucleotide identity (ANI) between all genomes. From...
Abstract Backgroud The genus Mesorhizobium is shown by phylogenomics to be paraphyletic and forms part of a complex that includes the genera Aminobacter, Aquamicrobium, Pseudaminobacter Tianweitania. relationships for type strains belong these need carefully re-evaluated. Results are evaluated based on phylogenomic analyses overall genome relatedness indices (OGRIs) 61 strains. According maximum likelihood phylogenetic tree concatenated sequences 539 core proteins constructed using bac120...
Legume species belonging to the genus Lespedeza are annual or perennial herb shrub plants that grow in northern hemisphere. They known for formation of root nodules, but little information is available about their microsymbionts. In this study, 58 root-nodule isolates from spp., obtained China and USA, were characterized using numerical taxonomic analysis phenotypic features, SDS-PAGE whole-cell proteins, DNA-DNA hybridization, 16S rRNA gene sequence cross-nodulation with selected legume...
Diazotrophic bacteria were isolated, in two different years, from the rhizosphere and rhizoplane of coffee (Coffea arabica L.) plants cultivated Mexico; they designated as type DOR SAd isolates. They showed characteristics family Acetobacteraceae, having some features common with Gluconacetobacter (formerly Acetobacter) diazotrophicus, only known N2-fixing species acetic acid bacteria, but differed this regard to several characteristics. Type isolates can be differentiated phenotypically...
Fifteen bacterial strains isolated from molasses grass ( Melinis minutiflora Beauv.) were identified as nitrogen-fixers by using the acetylene-reduction assay and PCR amplification of nifH gene fragments. These classified a unique group insertion sequence-PCR fingerprinting, SDS-PAGE protein patterns, DNA–DNA hybridization, 16S rRNA sequencing morphological characterization. Phylogenetic analysis indicated that these diazotrophic belonged to genus Azospirillum closely related lipoferum (with...
ABSTRACT To investigate the effects of land use and crop management on soybean rhizobial communities, 280 nodule isolates were trapped from 7 fields with different culture histories. Besides known Bradyrhizobium japonicum , three novel genospecies isolated these fields. Grassland (GL) maintained a higher diversity bradyrhizobia than other cultivation systems. Two ( spp. I III) distributed widely in all treatments, while sp. II was found only GL treatment. Cultivation soybeans increased...
This study assessed the diversity and composition of bacterial communities in four different soils (human-, penguin-, seal-colony impacted pristine soil) Fildes Region (King George Island, Antarctica) using 454 pyrosequencing with bacterial-specific primers targeting 16S rRNA gene. Proteobacteria, Actinobacteria, Acidobacteria, Verrucomicrobia were abundant phyla almost all soil samples. The types significantly geochemical properties community structure. Thermotogae, Cyanobacteria,...
Four rhizobia-like strains, isolated from root nodules of Pisum sativum and Vicia faba grown in Anhui Jiangxi Provinces China, were grouped into the genus Rhizobium but distinct all recognized species by phylogenetic analysis 16S rRNA housekeeping genes. The combined sequences genes atpD , recA glnII for strain CCBAU 23252 T showed 86.9 to 95 % similarity those known . All four strains had nodC nifH could form effective with faba, ineffective Phaseolus vulgaris did not nodulate Glycine max,...
