Rhizobium favelukesii sp. nov., isolated from the root nodules of alfalfa (Medicago sativa L).
On the basis of previously reported data and from new DNA-DNA hybridization results, phenotypic characterization and phylogenetic analyses, strains LPU83T and Or191 can be considered to be representatives of a novel species of the genus Rhizobium, for which the name RhZobium favelukesii sp.
A consolidated analysis of the physiologic and molecular responses induced under acid stress in the legume-symbiont model-soil bacterium Sinorhizobium meliloti
Multivariate analysis of global metabolome data served to unequivocally correlate specific-metabolite profiles with the extracellular pH, showing that at low pH the pentose-phosphate pathway exhibited increases in several transcripts, enzymes, and metabolites.
Comparative genomic analysis of Acinetobacter spp. plasmids originating from clinical settings and environmental habitats
Bacteria belonging to the genus Acinetobacter have become of clinical importance over the last decade due to the development of a multi-resistant phenotype and their ability to survive under multiple
Genomics of high molecular weight plasmids isolated from an on-farm biopurification system
Global analysis of the plasmid pool suggest that the analyzed BPS represents a key environment for further studies addressing the dissemination of MGEs carrying catabolic genes and pathway assembly regarding degradation capabilities.
A Stringent-Response-Defective Bradyrhizobium diazoefficiens Strain Does Not Activate the Type 3 Secretion System, Elicits an Early Plant Defense Response, and Circumvents NH4NO3-Induced Inhibition
Results indicate that the B. diazoefficiens stringent response integrates into the plant defense suppression and regulation of nodulation circuits in soybean, perhaps mediated by the type 3 secretion system.
Specificity traits consistent with legume‐rhizobia coevolution displayed by Ensifer meliloti rhizosphere colonization
The results suggest that consolidation of E. meliloti into its current symbiotic state should have occurred in a rhizobacterium that had already been adapted to rhizospheres of the Trifoliae tribe, and identified a subset of genes that impacted more severely the colonization of the roots of alfalfa than of pea.
Rhizobial plasmid pLPU83a is able to switch between different transfer machineries depending on its genomic background.
Structural and functional aspects of the CT of pLPU83a, an accessory replicon from Rhizobium sp.
rptA, a novel gene from Ensifer (Sinorhizobium) meliloti involved in conjugal transfer.
The Tn5-B13-insertion site of one of the mutants was cloned as an EcoRI-restricted DNA fragment that after subsequent isolation and sequencing demonstrated that a small open reading frame of 522 bp (designated rptA, for rhizobium plasmid transfer A) had been disrupted.
