The nitric oxide response in plant-associated endosymbiotic bacteria [PDF]
Nitric oxide (NO) is a gaseous signalling molecule which becomes very toxic due to its ability to react with multiple cellular targets in biological systems. Bacterial cells protect against NO through the expression of enzymes that detoxify this molecule

Phylogenetic analysis reveals an ancient gene duplication as the origin of the MdtABC efflux pump. [PDF]
The efflux pumps from the Resistance-Nodulation-Division family, RND, are main contributors to intrinsic antibiotic resistance in Gram-negative bacteria. Among this family, the MdtABC pump is unusual by having two inner membrane components.

Strains of Bradyrhizobium spp. form nitrogen-fixing symbioses with many legumes, including soybean. Although inorganic sulfur is preferred by bacteria in laboratory conditions, sulfur in agricultural soil is mainly present as sulfonates and sulfur esters.

Co-inoculation with Azospirillum brasilense in soybean cultivars subjected to water déficit [PDF]
This 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.

Role of the irr protein in the regulation of iron metabolism in Rhodobacter sphaeroides [PDF]
In Rhizobia the Irr protein is an important regulator for iron-dependent gene expression. We studied the role of the Irr homolog RSP_3179 in the photosynthetic alpha-proteobacterium Rhodobacter sphaeroides.

Swarming motility in Bradyrhizobium japonicum
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]
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.

A expansão da cultura da soja evidenciou uma alta especificidade hospedeira, requerendo a pesquisa de novas estirpes que apresentassem capacidade de nodular a soja e bom potencial de competição com a população de rizóbios naturalizada nos solos.

Molybdate transport by Bradyrhizobium japonicum bacteroids [PDF]
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.
