Interstrain Competition between Representatives of Indigenous Serotypes of Rhizobium trifolii.
The symbiotic characteristics of Rhizobium trifolii strains 1-01 and 2-01 were evaluated both individually and in various combinations on two cultivars (Mt. Barker and Woogenellup) of subterranean clover (Trifolium subterraneum L.). Nodules were observed on day 8 independent of cultivar or strain. Cultivar differences were measured in nodulating efficiency by 1-01 since 54% of the primary nodul...
متن کاملMolecular mechanism for loss of nodulation properties of Rhizobium trifolii.
Of 18 Rhizobium trifolii strains tested, 12 showed a high frequency of loss of nodulation ability after incubation in cultures at elevated temperatures. A correlation between loss of nodulation ability and loss of a large plasmid was demonstrated for R. trifolii. In some nonnodulating (Nod-) mutants, deletions occurred instead of total elimination of the plasmid molecule. The maximum curing eff...
متن کاملStudies on the Aspartic Acid Decarboxylase of Rhizobium Trifolii.
Virtanen and Laine (1937) were the first to suggest the existence of an aspartic acid decarboxylase in Rhizobium trifolii, by the isolation of beta-alanine from a 47-day fermentation mash containing aspartic acid. Shive and Macow (1946), working with hydroxyaspartic acid as a competitive analogue for aspartic acid in the metabolism of Escherichia coli, found that the addition of this compound t...
متن کاملA CORE OLIGOSACCHARIDE COMPONENT FROM SACCHARIDE OF Rhizobium trifolii ANU843
The major oligosaccharide from the core region of the lipopolysaccharide from R. trifolii ANU843 was isolated and its structure determined. It is a trisaccharide consisting of two galacturonic acid residues and one 3-deoxy-D-manno2octulosonic acid (KDO) residue. The two galacturonic acid residues are terminally linked alpha to the C-4 and C-7 atoms of KDO. This structure was determined through ...
متن کاملCell-associated pectinolytic and cellulolytic enzymes in Rhizobium leguminosarum biovar trifolii.
The involvement of Rhizobium enzymes that degrade plant cell wall polymers has long been an unresolved question about the infection process in root nodule symbiosis. Here we report the production of enzymes from Rhizobium leguminosarum bv. trifolii that degrade carboxymethyl cellulose and polypectate model substrates with sensitive methods that reliably detect the enzyme activities: a double-la...
