Genomic Diversity in the Endosymbiotic Bacterium Rhizobium leguminosarum [PDF]
Rhizobium leguminosarum bv. viciae is a soil α-proteobacterium that establishes a diazotrophic symbiosis with different legumes of the Fabeae tribe. The number of genome sequences from rhizobial strains available in public databases is constantly increasing, although complete, fully annotated genome structures from rhizobial genomes are scarce. In this

Congo Red Absorption by Rhizobium leguminosarum [PDF]
Congo red absorption is generally considered a contraindication of Rhizobium . However, R. leguminosarum takes up the dye on yeast extract-mannitol agar. The uptake of congo red varies among strains of R. leguminosarum , as shown elsewhere with strains of R.

Phenotypic, Molecular and Symbiotic Characterization of the Rhizobial Symbionts of Desmanthus paspalaceus (Lindm.) Burkart That Grow in the Province of Santa Fe, Argentina [PDF]
Desmanthus paspalaceus (Lindm.) Burkart belongs to the D. virgatus complex, subfamily Mimosoidae. The known potential as livestock fodder of several of these legumes prompted us to undertake a phenotypic, molecular, and symbiotic characterization of the ...

Rhizobium leguminosarum contains multiple chaperonin (cpn60) genes [PDF]
We have examined the heat shock response of Rhizobium leguminosarum. After normal growth at 28 degrees C, a 10 min heat shock at 37 degrees C induced the synthesis of proteins with approximate M(r) values of 90,000, 70,000, 60,000, 58,000, 19,000, 17,000 and 13,000. A monoclonal antibody raised against the E. coli Cpn60 cross-reacted with proteins of M(

Higher diversity of Rhizobium leguminosarum biovar viciae populations in arable soils than in grass soils [PDF]
The bacterial genetic diversity after long-term arable cultivation was compared with that under permanent grassland using replicated paired contrasts, Pea-nodulating Rhizobium leguminosarum populations were sampled from pairs of arable and grass sites at

Regulation of tryptophan genes in Rhizobium leguminosarum [PDF]
Twelve tryptophan auxotrophs of Rhizobium leguminosarum were characterized biochemically. They were grown in complex and minimal media with several carbon sources, in both limiting and excess tryptophan. Missing enzyme activities allowed assignment of all mutant to the trpE, trpD, trpB, or trpA gene, confirming earlier results with the same mutants ...

Movements of Ammonia in Rhizobium leguminosarum [PDF]
SUMMARY: Histidine-grown cells of Rhizobium leguminosarum can accumulate more than 100 mM free ammonia in the medium. Growth and respiration are unaffected by these concentrations of ammonia. Measurements of internal and external ammonia concentrations for cells grown on histidine or NH4CI as nitrogen sources suggest rapid equilibration of ammonia ...

Recombinant Nodulation Plasmids in Rhizobium leguminosarum [PDF]
SUMMARY: Plasmids pRL 1JI and pRL6JI, which carry determinants essential for symbiosis in Rhizobium leguminosarum field isolates 248 and 128C53, respectively, were both incompatible with two other transmissible plasmids that did not carry symbiotic determinants.
