Plant host habitat and root exudates shape soil bacterial community structure

There was also evidence for an indirect important impact of root exudates, through stimulation of SOM assimilation by a diverse bacterial community, which significantly shaped rhizosphere bacterial community structure.

The desert of Tataouine: an extreme environment that hosts a wide diversity of microorganisms and radiotolerant bacteria.

The phylogenetic diversity of prokaryotic communities exposed to arid conditions in the hot desert of Tataouine (south Tunisia) was estimated with a combination of a culture and - molecular-based analysis, revealing the presence of species related to Bacteria and Archaea.

Rhizosphere Soil Aggregation and Plant Growth Promotion of Sunflowers by an Exopolysaccharide-Producing Rhizobiumsp. Strain Isolated from Sunflower Roots

Inoculation with strain YAS34 modified soil structure around the root system, counteracting the negative effect of water deficit on growth, and it was shown that inoculation made the use of fertilizer more effective by increasing nitrogen uptake by sunflower plantlets.

Paenibacillus graminis sp. nov. and Paenibacillus odorifer sp. nov., isolated from plant roots, soil and food.

Sixteen gram-positive endospore-forming bacteria previously isolated from soil, plant rhizospheres, plant roots and pasteurized pureed vegetables were studied to determine their taxonomic positions and were assigned to two genomospecies using DNA-DNA hybridization, in agreement with rrs gene sequence analysis.

Taxonomic characterization of Ochrobactrum sp. isolates from soil samples and wheat roots, and description of Ochrobactrum tritici sp. nov. and Ochrobactrum grignonense sp. nov.

A large collection of bacterial strains, immunotrapped from soil and from the wheat rhizoplane, was subjected to polyphasic taxonomy by examining various pheno- and genotypic parameters, indicating that REP group K strains represent a new species.

Pseudomonas brassicacearum sp. nov. and Pseudomonas thivervalensis sp. nov., two root-associated bacteria isolated from Brassica napus and Arabidopsis thaliana.

16S rDNA (rrs) gene sequencing, DNA-DNA hybridization, biochemical characterization and siderophore typing showed that these isolates belong to two different species that are distinct from other species of the genus Pseudomonas, including P. corrugata.

Phenotypic and genomic evidence for the revision of Pseudomonas corrugata and proposal of Pseudomonas mediterranea sp. nov.

A new species, Pseudomonas mediterranea, is proposed for strains of phenon B, which could be clearly differentiated by the assimilation of mesotartrate, 2-ketogluconate and histamine and formed a cluster distinct from the P. corrugata type strain.

Identification of cellulolytic bacteria in soil by stable isotope probing.

Sequencing and phylogenetic analysis of 10 of these bands in DGGE profiles indicated that most sequences were closely related to sequences from organisms known for their ability to degrade cellulose or to uncultured soil bacteria.
