The genistein stimulon of Bradyrhizobium japonicum
Molecular Genetics and Genomics, 2008An initializing step in the rhizobia-legume symbiosis is the secretion of flavonoids by plants that leads to the expression of nodulation genes in rhizobia. Here we report the genome-wide transcriptional response of Bradyrhizobium japonicum to genistein, an isoflavone secreted by soybean. About 100 genes were induced in the wild type. This included all

Repeated sequence RSa is diagnostic for Bradyrhizobium japonicum and Bradyrhizobium elkanii
Biology and Fertility of Soils, 1996The genome of Bradyrhizobium japonicum and B. elkanii contains multiple copies of the repeated DNA sequence RSα. A collection of 18 B. japonicum, 4 B. elkanii and 72 other bacterial strains was screened by polymerase chain reaction (PCR) using a pair of primers specific for RSα. Only strains of B. japonicum and B.

Viability of Bradyrhizobium japonicum bacteriods [PDF]
Archives of Microbiology, 1987 Homogenates from soybean nodules, formed by 12 strains of Bradyrhizobium japonicum, were plated into yeast-extract mannitol agar containing 3 or 37 g mannitol 1-1. Viable counts ranged from 8.298 to 11.265 log10 cells-gram nodule-1. When monitored over the life cycle of the symbiosis, the viability of strains USDA 110 and USDA 123 increased with days ...

Spread of Rhizobium and Bradyrhizobium in soil
Soil Biology and Biochemistry, 1993Abstract Movement of Rhizobium loti and Bradyrhizobium sp., from established Lotus corniculatus and L. pedunculatus respectively, was studied to determine if lack of root-nodule bacteria would limit nodulation following natural reseeding. High populations of root-nodule bacteria occurred in the soil under established plants. However, movement

The Parasponia-Bradyrhizobium Symbiosis
2018This chapter reviews progress in understanding of Parasponia nodulation and nitrogen fixation with particular emphasis on a comparative analysis of this knowledge relative to the rapidly advancing legume nodulation field. The structure of mature Parasponia nodules appears quite different to that of tropical legume nodules even though both are elicited ...

Nine slow-growing rhizobia isolated from effective nodules on peanut (Arachis hypogaea) were characterized to clarify the taxonomic status using a polyphasic approach. They were assigned to the genus Bradyrhizobium on the basis of 16S rRNA sequences.

IMPROVING BRADYRHIZOBIUM — SOYBEAN SYMBIOSIS
Environmental, Health and Humanity Issues in the Down Danubian Region, 2008The objective of this study was to assess the effects of Nitragin application, Nitragin and PGPR (plant growth promoting rhizobacteria) — Azotobacter and Nitragin re-inoculation 30 days after first inoculation of soybean. The trial with different inoculation methods was established at Rimski Sancevi experiment field in 2001 and 2002.

Survival of inoculant Bradyrhizobium japonicum in an Andosol
Biology and Fertility of Soils, 1996The survival of an antibiotic-resistant mutant of a commercial inoculant Bradyrhizobium japonicum strain, A1017ks, was studied in a volcanic ash soil (Andosol) in comparison with a non-volcanic ash soil (Fluvisol) over a period of 84 days. In a non-sterile soil system, the population decline in the Andosol (15% or 1.2 log units) was larger than in the ...

Cuffed and Exposed — Perp-Walking Bradyrhizobium
New England Journal of Medicine, 2013Diarrhea and intestinal inflammation after allogeneic hematopoietic stem-cell transplantation can be caused by pathogenic bacteria and viruses or by graft-versus-host disease (GVHD). Bacterial cultures, viral polymerase-chain-reaction (PCR) assays, and histologic analyses of intestinal biopsy specimens are imperfect at distinguishing infection from ...

The symbiotic bradyrhizobia of Aeschynomene indica and the aquatic budding bacterium Blastobacter denitrificans have much in common and this study broadens the characters that are shared between the two. The 23S rRNA gene sequences of the bradyrhizobial isolates were most similar to each other and to the sequence of Bl. denitrificans.
