The intensity of drought-induced oxidative processes in soybeans depends on symbiosis with Bradyrhizobium strains [PDF]
Journal of Central European Agriculture, 2022 The intensity of drought-induced oxidative processes by the degree of superoxide anion radical generation and the activity of NADPH oxidase in soybean associated with different activity and virulence of Bradyrhizobium strains were studied. The importance

Agronomy, 2023 Low soil fertility in savanna soils has been linked to low crop yields, with nitrogen being the most limiting factor in crop yield. Soil used in this pot experiment was obtained from Motshephiri village with low total N, low NO3− and high NH4+.

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.

Anaerobic Reduction of Nitrate to Nitrous Oxide Is Lower in Bradyrhizobium japonicum than in Bradyrhizobium diazoefficiens. [PDF]
Microbes Environ, 2017 When soil oxygen levels decrease, some bradyrhizobia use denitrification as an alternative form of respiration. Bradyrhizobium diazoefficiens (nos+) completely denitrifies nitrate (NO3−) to dinitrogen, whereas B.

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

Biochemical and physiological characterization of Bradyrhizobium japonicum [PDF]
International Journal of Chemical Studies, 2020 Soybean [Glycine max (L.) Merrill] is cultivated intensively in India. Rhizobium sp. associated with it derives nitrogen (N) by biological nitrogen fixation under field conditions. Out of total 25 isolated sp. from functional root nodules of soybean plants on congo-red yeast extract mannitol agar medium, 20 slow grower Bradyrhizobium sp.

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.

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.

Molecular identification of Bradyrhizobium japonicum strains isolated from root nodules of soybean (Glycine max L.) [PDF]
Zbornik Matice Srpske za Prirodne Nauke, 2017 The aim of this study was to isolate and identify Bradyrhizobium japonicum strains on the basis of molecular characteristics. From root nodules of different soybean cultivars were obtained 56 isolates, characterized according to morphological ...
