Abstract:: The primary purpose of this investigation was to determine the conditions necessary for the preparation of cell-free extracts of nodule bacteroids capable of catalysing the reduction of acetylene to ethylene and nitrogen to ammonia. Initial investigations were conducted to determine whether intact soybean root nodules would reduce acetylene to ethylene...

Abstract:: The transcriptional promoter sequences for the Rhizobium meliloti nitrogen fixation genes nifA and nifB were cloned to a β-galactosidase gene fusion plasmid vector and transferred by homologous recombination to a specialized transducing phage. The promoter fusions were then transduced to a recombination deficient strain of Escherichia coli as single-copy lysogens...

Abstract:: A major objective of this investigation was to determine the possible roles, if any, of poly-β-hydroxybutyrate and products of its metabolic breakdown in symbiotic nitrogen fixation by nodule bacteroids. Changes in poly -β- hydroxybutyrate content and in activities of nitrogenase, β-hydroxybutyrate dehydrogenase, and isocitrate lyase were studied under various conditions...
