Pulsed-field gel electrophoresis studies of Rhizobiaceae
, 1989 The migration properties of circular, covalently closed (ccc) and linear DNAs were studied in pulsed-field gel electrophoresis as a model system for resolving large plasmids in the Rhizobiaceae. The effects of varying pulse time and agarose concentration on the electrophoretic mobility cccDNAs, ranging from 2 kilobase pairs (kb) to 16 kb, was ...

Conservation of noIR in the Sinorhizobium and Rhizobium Genera of the Rhizobiaceae Family [PDF]
Molecular Plant-Microbe Interactions, 1998 In Sinorhizobium meliloti the NolR repressor displays differential negative regulation of nodulation genes and is required for optimal nodulation. Here, we demonstrate that the NolR function is not unique to S.

FtcR Is a New Master Regulator of the Flagellar System ofBrucella melitensis16M with Homologs inRhizobiaceae [PDF]
Journal of Bacteriology, 2006 ABSTRACTThe flagellar regulon ofBrucella melitensis16M contains 31 genes clustered in three loci on the small chromosome. These genes encode a polar sheathed flagellum that is transiently expressed during vegetative growth and required for persistent infection in a mouse model.

Aerobic Vaginal Microflora in Gestational and Non-Gestational Bitches (Canis lupus familiaris) [PDF]
AnimalsThe vaginal tract comprises commensal microorganisms, which play an essential role in the health of the reproductive tract. Any dysbiosis in the vaginal microenvironment may lead to severe urinary tract infections or even infertility. This study aimed to

DNA:DNA Hybridization Studies of Rhizobium japonicum and Related Rhizobiaceae [PDF]
Microbiology, 1981 The symbiotic nitrogen-fixing bacteria associated with soybeans (Glycine max) have been classified routinely as Rhizobium japonicum. DNA:DNA hybridization studies were conducted to estimate the genetic relationships of strains labelled as R. japonicum to clarify their taxonomic status.

Cyclic beta-(1,2)-glucan synthesis in Rhizobiaceae: roles of the 319-kilodalton protein intermediate [PDF]
Journal of Bacteriology, 1996 Cyclic beta-(1,2)-glucans are synthesized by members of the Rhizobiaceae family through protein-linked oligosaccharides as intermediates. The protein moiety is a large inner membrane molecule of about 319 kDa. In Agrobacterium tumefaciens and in Rhizobium meliloti the protein is termed ChvB and NdvB, respectively. Inner membranes of R.

The genomes of the family Rhizobiaceae: size, stability, and rarely cutting restriction endonucleases [PDF]
Journal of Bacteriology, 1991 The lack of high-resolution genetic or physical maps for the family Rhizobiaceae limits our understanding of this agronomically important bacterial family. On the basis of statistical analyses of DNA sequences of the Rhizobiaceae and direct evaluation by pulsed-field agarose gel electrophoresis (PFE), five restriction endonucleases with AT-rich target ...

Analysis of Stable Low-Molecular-Weight RNA Profiles of Members of the Family Rhizobiaceae [PDF]
Applied and Environmental Microbiology, 1998 ABSTRACT Staircase electrophoresis in polyacrylamide gels was used to analyze the stable low-molecular-weight (LMW) RNA profiles of 24 type strains belonging to the family Rhizobiaceae . This new electrophoretic technique results in good separation of the molecules forming the LMW RNA profiles. Differences
