Induction by Bradyrhizobium diazoefficiens of different pathways for growth in D-mannitol or L-arabinose leading to pronounced differences in CO2 Fixation, O2 consumption, and lateral-flagellum production
(Frontiers Research Foundation, 2018-06)
Bradyrhizobium diazoefficiens, a soybean N2-fixing symbiont, constitutes the basic input in one of the most prominent inoculant industries worldwide. This bacterium may be cultured with D-mannitol or L-arabinose as ...
A stringent response-defective Bradyrhizobium diazoefficiens does not activate the type-3-secretion system, elicits early plant defense, and circumvents NH 4 NO 3 -induced inhibition of nodulation
(American Society for Microbiology, 2021-04-13)
When subjected to nutritional stress, bacteria modify their amino acid metabolism and cell division activities by means of the stringent response, which is controlled by the Rsh protein in alphaproteobacteria. An important ...
The Bradyrhizobium diazoefficiens two-component system NtrYX has a key role in symbiotic nitrogen fixation of soybean plants and cbb 3 oxidase expression in bacteroids
(Springer, 2019-07)
Aims: Bradyrhizobium diazoefficiens is a soil bacterium capable of establishing nitrogen-fixing symbiosis with soybean plants, an important crop for food production worldwide. This interaction is under the control of several ...
Evaluation of bradyrhizobia strains isolated from field-grown soybean plants in Argentina as improved inoculants
(Springer, 2010-09-22)
Bradyrhizobium strains were isolated from nodules obtained from field-grown soybean plants sampled in 12 soybean production locations in Argentina. These fields had been annually cropped with soybean and did not show ...
La fijación simbiótica de nitrógeno en soja: Nodulación, inoculantes y métodos de inoculación
(Asociación Civil Ciencia Hoy, 2005-02)
La soja es una leguminosa, que al interactuar con bacterias (rhizobios), logra establecer una relación de tipo simbiótico en la cual los microorganismos son albergados por las raíces y allí logran que el nitrógeno gaseoso ...
A new PGPR co-inoculated with Bradyrhizobium japonicum enhances soybean nodulation
(Elsevier Gmbh, 2014-01)
A new PGPR (plant growth promoting rhizobacteria) strain was isolated from soybean seeds and the bacterial mechanisms related to plant growth promotion were evaluated and characterized. Isolates were genotypically compared ...
Soybean-nodulating strains with low intrinsic competitiveness for nodulation, good symbiotic performance, and stress-tolerance isolated from soybean-cropped soils in Argentina
(Frontiers Media, 2019-05-14)
Soybean is the most important oilseed in the world, cropped in 120-130 million hectares each year. The three most important soybean producers are Argentina, Brazil, and United States, where soybean crops are routinely ...
Structure and biological activities of lipochitooligosaccharide nodulation signals produced by Bradyrhizobium japonicum USDA 138 under saline and osmotic stress
(2014-02)
The establishment of a symbiotic interaction involves a signal exchange between the host legume (flavonoids) and the nitrogen-fixing rhizobia (nodulation factors (NFs)). Likewise, abiotic stress conditions, such as salinity ...
The benefits of foliar inoculation with Azospirillum brasilense in soybean are explained by an auxin signaling model
(Springer, 2017-12)
Azospirillum sp. is one of the most studied genera of plant growth-promoting rhizobacteria (PGPR). The ability of Azospirillum sp. to promote plant growth has been associated with its ability to produce several phytohormones, ...
Swimming performance of Bradyrhizobium diazoefficiens is an emergent property of its two flagellar systems
(Nature Publishing Group, 2016-04)
Many bacterial species use flagella for self-propulsion in aqueous media. In the soil, which is a complex and structured environment, water is found in microscopic channels where viscosity and water potential depend on the ...
