Hemoproteins of Bradyrhizobium japonicum Cultured Cells and Bacteroids.
The hemoprotein content of 17 strains of Bradyrhizobium japonicum bacteroids from field-grown plants and the corresponding strains of cultured cells was determined spectrally. The major terminal oxidases, cytochromes (cyt) aa(3) and o, were present in all strains of cultured cells. cyt aa(3) was present in significant amounts in bacteroids only in strains of DNA homology group II. cyt o appeare...
متن کاملInvolvement of glutamate in the respiratory metabolism of Bradyrhizobium japonicum bacteroids.
Bradyrhizobium japonicum bacteroids were isolated anaerobically and supplied with 14C-labeled succinate, malate, aspartate, or glutamate for periods of up to 60 min in the presence of myoglobin to control the O2 concentration. Succinate and malate were absorbed about twice as rapidly as glutamate and aspartate. Conversion of substrate to CO2 was most rapid for malate, followed by succinate, glu...
متن کاملFormation of Novel Polysaccharides by Bradyrhizobium japonicum Bacteroids in Soybean Nodules.
Certain strains of Bradyrhizobium japonicum form a previously unknown polysaccharide in the root nodules of soybean plants (Glycine max (L.) Merr.). The polysaccharide accumulates inside of the symbiosome membrane-the plant-derived membrane enclosing the bacteroids. In older nodules (60 days after planting), the polysaccharide occupies most of the symbiosome volume and symbiosomes become enlarg...
متن کاملAerobic vanillate degradation and C1 compound metabolism in Bradyrhizobium japonicum.
Bradyrhizobium japonicum, a symbiotic nitrogen-fixing soil bacterium, has multiple gene copies for aromatic degradation on the genome and is able to use low concentrations of vanillate, a methoxylated lignin monomer, as an energy source. A transcriptome analysis indicated that one set of vanA1B, pcaG1H1, and genes for C(1) compound catabolism was upregulated in B. japonicum USDA110 cells grown ...
متن کاملPutative porin of Bradyrhizobium sp. (Lupinus) bacteroids induced by glyphosate.
Application of glyphosate (N-[phosphonomethyl] glycine) to Bradyrhizobium sp. (Lupinus)-nodulated lupin plants caused modifications in the protein pattern of bacteroids. The most significant change was the presence of a 44-kDa polypeptide in bacteroids from plants treated with the higher doses of glyphosate employed (5 and 10 mM). The polypeptide has been characterized by the amino acid sequenc...
