Use of nitrous oxide as the terminal electron acceptor during growth and respiration of Bradyrhizobium Japonicum USDA 143
Bradyrhizobium japonicum USDA 143 grew chemoorganotrophically when supplied with exogenous nitrous oxide as the terminal electron acceptor, or as the alternate terminal electron acceptor to nitrate under anoxic conditions. Cell growth and dissimilatory N₂O reduction were significantly inhibited by …

The effect of phosphorus fertilizer and bradyrhizobium innoculation on grain yield and nutrients accumulation in two chickpea (Cicer aritienum L.) genotypes
Chickpea (Cicer aritienum L.) is an ancient crop that originated in South-Eastern Turkey and belongs to the genus Cicer, tribe Cicereae, and family Fabaceae. Chickpea has the ability to fix atmospheric nitrogen (N) for its growth. However, chickpea productivity not only depends on N2 fixation or …

The symbiotic interaction of Bradyrhizobium japonicum with bambara groundnut and cowpea and the effects of NOD gene-inducers, daidzein and genistein
The aim of this project was to investigate whether nodulation, and nitrogen concentration of legumes can be increased by providing additional nod geneinducer compounds. Both daidzein and genistein are nod gene-inducers for rhizobia nodulating cowpea, bambara groundnut, soybean and the common bean.

Rhizobia inoculant effects on bambara groundnut growth and yield in Namibia
… Kavango region to ascertain how well the various Bradyrhizobium strains promote nodulation and yield components among three varieties of Bambara groundnut was conducted. The study also evaluated the strains that are most competitive to reach the roots and promote nodulation in a given period. For …

Systematics, Specificity, and Ecology of New Zealand Rhizobia
… legumes of this study were nodulated by diverse Bradyrhizobium spp. that had nodA genotypes typical of Australian and European species. The origins of these bacteria can not be categorically determined. However the evidence is presented to suggest that nodulating Mesorhizobium spp. arrived with …
