Co-inoculation with Azospirillum brasilense in soybean cultivars subjected to water déficit [PDF]
Revista Brasileira de Engenharia Agrícola e AmbientalThis study aimed to verify the effect of co-inoculation, association between Azospirillum brasilense and Bradyrhizobium japonicum bacteria, on soybean plants subjected to water deficit at two sowing dates.

Swarming motility in Bradyrhizobium japonicum
Research in Microbiology, 2013 Flagellar-driven bacterial motility is an important trait for colonization of natural environments. Bradyrhizobium japonicum is a soil species that possesses two different flagellar systems: one subpolar and the other lateral, each with a filament formed by a different set of flagellins.

Chemotaxis of Bradyrhizobium japonicum to soybean exudates [PDF]
Applied and Environmental Microbiology, 1991 The chemotactic response of Bradyrhizobium japonicum toward soybean seed and root exudates was examined. Assays using various isoflavones and fractionated exudate indicated that isoflavones are not the principal attractants in exudates. Likewise, induction of nod genes with isoflavones or seed exudate before assay did not enhance chemotaxis.

Molybdate transport by Bradyrhizobium japonicum bacteroids [PDF]
Journal of Bacteriology, 1988 Bacteroid suspensions of Bradyrhizobium japonicum USDA 136 isolated from soybeans grown in Mo-deficient conditions were able to transport molybdate at a nearly constant rate for up to 1 min. The apparent Km for molybdate was 0.1 microM, and the Vmax was about 5 pmol/min per mg (dry weight) of bacteroid.

Citrate as a siderophore in Bradyrhizobium japonicum
Journal of Bacteriology, 1990 Under iron-limiting conditions, many bacteria secrete ferric iron-specific ligands, generically termed siderophores, to aid in the sequestering and transport of iron. One strain of the nitrogen-fixing soybean symbiont Bradyrhizobium japonicum, 61A152, was shown to produce a siderophore when 20 B.

Nickel accumulation and storage in Bradyrhizobium japonicum [PDF]
Applied and Environmental Microbiology, 1990 Hydrogenase-derepressed (chemolithotrophic growth conditions) and heterotrophically grown cultures of Bradyrhizobium japonicum accumulated nickel about equally over a 3-h period. Both types of cultures accumulated nickel primarily in a form that was not exchangeable with NiCl2, and they accumulated much more Ni than would be needed for the Ni ...

Cytokinin Production by Bradyrhizobium japonicum [PDF]
Plant Physiology, 1989 Although there is considerable circumstantial evidence for the involvement of cytokinins in legume nodulation, the cytokinins produced by rhizobia have not been well characterized. Bradyrhizobium japonicum 61A68, a bacterium which nodulates soybean (Glycine max [L.] Merr.), was grown in defined medium.

Siderophore Utilization by Bradyrhizobium japonicum [PDF]
Applied and Environmental Microbiology, 1993 Bradyrhizobium japonicum USDA 110 and 61A152 can utilize the hydroxamate-type siderophores ferrichrome and rhodotorulate, in addition to ferric citrate, to overcome iron starvation. These strains can also utilize the pyoverdin-type siderophore pseudobactin St3. The ability to utilize another organism's siderophores may confer a
