Electroporation of Bradyrhizobium japonicum
Molecular and General Genetics MGG, 1990Electroporation offers a fast, efficient and reproducible way to introduce DNA into bacteria. We have successfully used this technique to transform two commercially important strains of Bradyrhizobium japonicum, the nitrogen-fixing soybean symbiont. Initially, electroporation conditions were optimized using plasmid DNA which had been prepared from the ...

Viability of Bradyrhizobium japonicum bacteriods
Archives of Microbiology, 1987Homogenates 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 ...

Degradation of catechin by Bradyrhizobium japonicum
Biodegradation, 1997Rhizobia utilize phenolic substances as sole carbonsource. Bradyrhizobium japonicum utilizescatechin, a unit of condensed tannin as carbonsource. To establish the degradative pathway ofcatechin, the products of catechin degradation wereisolated by paper chromatography and TLC andidentified by HPLC, UV, IR and NMR spectra.

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.

BRADYRHIZOBIUM JAPONICUM AND PHOSPHOBACTERIA FOR SOYBEAN
Madras Agricultural Journal, 1998The effect of individual and combined inoculations of Bradyrhizobiumand phosphobacteria along with application of super phosphate. rock phosphate and FYM on the growth and yield of soybean were studied. The combined inoculation of Bradyrhizobium and phosphobacteria was proved to be better than individual inoculations. The combined inoculations with FYM+

A Motility Revertant of the ndvB Mutant of Bradyrhizobium japonicum
Current Microbiology, 2003A motility revertant of a Bradyrhizobium japonicum ndvB mutant was isolated and characterized. The ndvB mutants of B. japonicum have been reported to be osmotically sensitive, as well as defective in motility, periplasmic cyclic beta-(1-->3), (1-->6)-D-glucan synthesis, and symbiosis with soybean.

Analysis of the secretome of the soybean symbiont Bradyrhizobium japonicum
Journal of Biotechnology, 2009Proteins from the supernatant of Bradyrhizobium japonicum were separated by two-dimensional gel electrophoresis and stained with Coomassie. This revealed more than 100 protein spots. Sixty-eight proteins were identified by mass spectrometry. Thirty-five are predicted to contain an N-terminal signal peptide characteristic for proteins transported by the

Regulation of nod gene expression in Bradyrhizobium japonicum
Molecular and General Genetics MGG, 1988The best inducers of nod::lacZ translational fusions in Bradyrhizobium japonicum are isoflavones, primarily genistein and daidzein. Upstream of the nodABC genes in B. japonicum is a novel gene, nodY, which is coregulated with nodABC. Measurements of the activity of lacZ fusions to the nodD gene of B.
