  • Effect of oxygen on the synthesis, activity and breakdown of the rhizobium denitrification system

    O'Hara, G.W.; Daniel, Roy M.; Steele, K.W. (1983)
    The synthesis, activity and breakdown of the denitrifying enzymes of Rhizobium japonicum, R. lupini and R. meliloti were found to be regulated by O₂. Nitrogen oxide reductases were present in anaerobically grown and symbiotic ...
  • Effect of rhizobial strain and host plant on nitrogen isotopic fractionation in legumes

    Steele, K.W.; Bonish, P.M.; Daniel, Roy M.; O'Hara, G.W. (American Society of Plant Biologists, 1983)
    Lotus pedunculatus L., Medicago sativa L., Macroptilium atropurpureum, Glycine max, and Trifolium repens L. were grown in a N-free medium and inoculated with one of ten Rhizobium strains. Dry matter, N content, and tV5N ...
  • Nitrogen losses from soils caused by Rhizobium-dependent denitrification

    O'Hara, G.W.; Daniel, Roy M.; Steele, K.W.; Bonish, P.M. (Elsevier, 1984)
    Biological nitrogen fixation by the Rhizobium-legume symbiosis is of considerable agronomic importance, and most research on rhizobia is aimed at a better understanding of symbiotic nitrogen fixation (e.g. Hardy er nl.. ...
  • Rhizobial denitrification: A review

    O'Hara, G.W.; Daniel, Roy M. (1985)
    The root-nodule bacteria, Rhizobium spp, in a symbiotic relationship with leguminous plants, make an important contribution to nitrogen input in soils. For this reason most research on rhizobia has as its aim a better ...
