QTLs underlying the genetic interrelationship between efficient compatibility of Bradyrhizobium strains with soybean and genistein secretion by soybean roots. [PDF]

PLoS ONE, 2018
Soybean plants establish symbiotic relationships with soil rhizobia which form nodules on the plant roots. Nodule formation starts when the plant roots exudate isoflavonoids that induce nod gene expression of a specific Bradyrhizobium.

Iron Fertilization of Soybean Genotypes Differing in Iron Use Efficiency Under Alkaline Conditions: Implications for Yield and Seed Nutritional Quality

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 544-557, August 2026.
ABSTRACT Background Soybean, a nutritionally important protein‐ and oil‐rich legume, is highly sensitive to iron (Fe) deficiency under alkaline conditions, where reduced Fe availability limits growth, yield, and seed quality. Effective biofortification therefore requires increasing seed Fe while reducing phytate that restricts Fe bioavailability.

Three Decades of Soil N2O Research—Insights and Gaps

Global Change Biology, Volume 32, Issue 8, August 2026.
Progress in N2O Research and Key Breakthroughs and Transitions from 1990 to 2025 across three domains: (A) process understanding, (B) microbial ecology, and (C) modelling of soil N2O emissions. ABSTRACT Nitrous oxide (N2O) is a potent greenhouse gas (GHG) whose atmospheric concentration continues to rise, largely driven by nitrogen (N) inputs to ...

Efficient DNA transformation of Bradyrhizobium japonicum by electroporation [PDF]

Applied and Environmental Microbiology, 1990
Intact cells of Bradyrhizobium japonicum USDA 110 were transformed with a 30-kilobase plasmid to efficiencies of 10(6) to 10(7) transformants per microgram by high-voltage electroporation. The technique was reliable and simple, with single colonies arising from transformed cells within 5 days of antibiotic selection. Plasmid DNA from B.

Controlling Damping - Off Disease on Cotton Seedlings Caused by Rhizoctonia solani and Fusarium oxysporum Via Plant Growth-Promoting Rhizobacteria (PGPR) [PDF]

Journal of Agricultural Chemistry and Biotechnology
Plant growth promoting rhizobacteria (PGPR) are a group of bacteria that can be enhance the growth of plant directly or indirectly. These bacteria are commonlyfound in soil associated with roots of plants.

Enhancing winter canola integration into soybean cropping systems through relay intercropping

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Winter canola (Brassica napus L.) has the potential to enhance the sustainability of soybean‑based cropping systems when integrated as a relay‑intercropped winter oilseed. A critical factor for successful overwinter survival is timely seeding that allows sufficient rosette development before dormancy.

Gibberellin oxidase activities in Bradyrhizobium japonicum bacteroids

Phytochemistry, 2014
Bradyrhizobium japonicum bacteroids isolated from root nodules of soybean (Glycine max.) plants converted the gibberellin (GA) precursor [(14)C1]GA12 into several products identified by combined gas chromatography-mass spectrometry as [(14)C1]GA24, [(14)C1]GA9, [(14)C1]GA15, GA9 17-nor-16-one and unidentified products.

Nutritional Value Of Cowpea (Vigna Unguiculata L. Walp) Grain Grown Under Different Soil Moisture As Affected to the Dual Inoculation with Nitrogen Fixing Bacteria and Arbuscular Mycorrhizal Fungi [PDF]

Bulgarian Journal of Soil Science, 2016
The study was performed to evaluate the nutritional value and antioxidant properties of cowpea grain, where plants were grown under conditions of tripartite symbiosis (cowpea plants, nitrogen-fixing bacteria (Bradyrhizobium japonicum) and arbuscular ...

Plant growth‐ promoting bacteria inoculation and co‐inoculation effects on Palisade grass (Urochloa brizantha cv. Marandu) in ferralsol in Amazonas State, Brazil

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Deforestation is primarily driven by three main factors the conversion of the Amazon rainforest into pastureland, agriculture, and mining, as well as land invasion. These pastures are mostly degraded, and it is necessary to restore their productive capacity. Microbial inoculants can be used to increase nutrient use efficiency. The objective of
