A CORE OLIGOSACCHARIDE COMPONENT FROM SACCHARIDE OF Rhizobium trifolii ANU843
نویسنده
چکیده
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 use of ‘Hand 13C-n.m.r. spectroscopy, f.a.b.-m.s., and g.l.c.m.s. techniques. This oligosaccharide had not previously been reported to be present in the lipopolysaccharides from Gram-negative bacteria.

Distribution of O-acetyl groups in the exopolysaccharide synthesized by Rhizobium leguminosarum strains is not determined by the Sym plasmid.
The patterns of O-acetylation of the exopolysaccharide (EPS) from the Sym plasmid-cured derivatives of Rhizobium leguminosarum bv. trifolii strain LPR5, R. leguminosarum bv. trifolii strain ANU843 and R. leguminosarum bv. viciae strain 248 were determined by 1H and 13C NMR spectroscopy. Beside a site indicative of the chromosomal background, these strains have one site of O-acetylation in commo...
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...
متن کاملComparison of characteristics of the nodX genes from various Rhizobium leguminosarum strains.
We have analyzed the nucleotide sequences of the nodX genes from two strains of Rhizobium leguminosarum bv. viciae able to nodulate Afghan peas (strains A1 and Himalaya) and from two strains of R. leguminosarum bv. trifolii (ANU843 and CSF). The nodX genes of strains A1 and ANU843 were shown to be functional for the induction of nodules on Afghan peas. To analyze the cause of phenotypic differe...
متن کاملReexamination of the presence and linkage of 3-hydroxybutyryl substituents in the acidic capsular polysaccharide of Rhizobium trifolii 0403.
We resolved previous conflicting results concerning the presence of 3-hydroxybutyryl substituents on the extracellular acidic polysaccharide from Rhizobium trifolii 0403. These substituents were indeed present in the polysaccharide and in the oligosaccharide fragments obtained by hydrogen fluoride solvolysis of the extracellular and capsular polysaccharides of the bacteria grown on plates. The ...
متن کاملRhizobium cellulase CelC2 is essential for primary symbiotic infection of legume host roots.
The rhizobia-legume, root-nodule symbiosis provides the most efficient source of biologically fixed ammonia fertilizer for agricultural crops. Its development involves pathways of specificity, infectivity, and effectivity resulting from expressed traits of the bacterium and host plant. A key event of the infection process required for development of this root-nodule symbiosis is a highly locali...
