Summary: The study evaluated the performance of indigenous Bradyrhizobia strains in soybean cultivation, with B. elkanii IS-2 identified as the most efficient for Philippines cultivars and B. diazoefficiens SK-5 for Japanese and Brazilian cultivars. Positive correlation was found between symbiotic efficiency and nitrogenase activity, indicating efficient N-fixation by indigenous strains. This research provides insights for soybean inoculation in the Philippines.

Summary: Symbiotic partnership with rhizobial bacteria allows legumes to grow without nitrogen fertilizer. Legumes produce peptides that bind haem to reduce its availability, inducing iron-starvation response in rhizobia, which is required for nitrogenase activity.

Summary: This study investigates the effects of biochar amendment, nitrogen and phosphorus supply on soybean growth and nutrient uptake. The results show that biochar application significantly increases soybean biomass and enhances the symbiotic performance of Bradyrhizobium japonicum. Additionally, biochar improves nitrogen uptake and has a positive correlation with shoot and root biomass.

Summary: In this study, four new species of rhizobia were isolated from high trehalose-accumulating soybean genotypes, and one of them, B. daqingense, showed higher nodulation and nitrogen fixation activity, as well as plant growth promotion traits and phosphate-solubilizing potential. B. daqingense could be a potential candidate for conferring drought tolerance in soybean under simulated stress conditions, and further research is warranted.

Summary: This study measured and analyzed the morphological and nutritive traits of Sehima nervosum germplasm collected from different agro-climatic conditions in India. The results showed wide variability among accessions, with plant height, number of tillers per tussock, and number of nodes per tiller accounting for significant variation. The germplasm with substantial variability is a valuable genetic resource for developing new cultivars.

Summary: This study investigated the compatibility between adzuki bean and Bradyrhizobium USDA strains, as well as the relation between the genetic diversity of indigenous adzuki bean-nodulating bradyrhizobia and their geographical distribution in Japan. The findings revealed a strong and significant correlation between Japan's indigenous adzuki bean-nodulating bradyrhizobial community and latitude, longitude, annual mean temperature, and electrical conductivity.

Summary: This study investigated the mutual relations between different soybean cultivars and two strains of Bradyrhizobium japonicum after mixed inoculation. The results showed that the use of a mixture of B. japonicum 46 and B. japonicum KB11 strains promoted a more even distribution of rhizobia in the nodules of soybean cultivars and led to an increase in nodulation, symbiotic nitrogen fixation, and soybean yield.

Summary: Insufficient water supply significantly reduces the activity of nitrogen fixation by legume-rhizobial symbiotic systems. Comprehensive research on their resistance to water stress and the application of metal nanocarboxylates in the inoculation suspension can mitigate the negative effects of water stress. Specifically, cobalt nanocarboxylate stimulates molecular nitrogen fixation, germaniumcarboxylate nanoparticles make symbiotic systems less sensitive to water stress, and chromium nanocarboxylate enhances nodulation and nitrogen-fixing activity under optimal conditions.
