Rhizobium–plant signal exchange
Nature, 1992Initial stages in the Rhizobium-legume symbiosis can be thought of as a reciprocal molecular conversation: transmission of a gene inducer from legume host to bacterium, with ensuing bacterial synthesis of a morphogen that is transmitted to the plant, switching the developmental fate of the legume root.

Interspecific transformation in Rhizobium
Archiv f�r Mikrobiologie, 1967Two characters, “Penicillin resistance” and “fructose utilizing ability”, were transferred in the recipient Rhizobium cowpea (source—Ground nut roots) with the help of the DNA extracted from Rhizobium phaseoli culture (source—French bean roots). The recipient culture enters the logarithmic growth phase at the end of 60 min.

LYSOGENY IN RHIZOBIUM TRIFOLII
Canadian Journal of Microbiology, 1961A phage-like particle (phage i) found in filtrates of Rhizobium trifolii (strain RT 9) did not produce plaques but induced development of two different phages in a presumed defective lysogenic strain (RT 10). These induced phages (phages 9 and 10) differed in their host ranges and produced plaques on strains RT 9 and RT 10, respectively.

Rhizobium strains (one each of Rh. japonicum, Rh. lupini, Rh. leguminosarum) take up 2-ketoglutaric acid in general much faster and from lower concentrations in the medium than strains of Escherichia coli, Bacillus subtilis and Chromobacterium violaceum. A strain of Enterobacter aerogenes, however, is more similar to some Rhizobium strains.

Comparison between Rhizobium galegae and Rhizobium meliloti plasmid contents
Letters in Applied Microbiology, 1990Plasmid profiles of two strains of a newly classified rhizobial species-Rhizobium galegae-were compared with the profiles of several strains of another fast-growing Rhizobium species-Rhizobium meliloti. The existence of a plasmid DNA band with a lower electrophoretic mobility than the R.

Seven of eight Rhizobium strains survived 70° C but not 80° C for half an hour in liquid media. The proportion of cells surviving heat treatment varied with the composition of the media and the age of the cultures, but did never exceed 0.7%. It appears that this heat resistance is not an effect of sporulation, according to the classical definition of a

Transformation in Rhizobium japonicum
Archiv für Mikrobiologie, 1969The transformation of streptomycin resistance in Rhizobium japonicum was studied. The susceptible strain 211 was selected from sixty strains and one step mutant resistant to streptomycin in concentration 1 mg per 1 ml was used as the donor. The peak of the competence curve appeared at the ninth hour of growth; the frequency, when the homologous strain ...

?????????????????????????????? ???????????????????? ???????????? Rhizobium radiobacter
2011The possibility of Rhizobium radiobacter strains isolated from rhizosphere of winter wheat to produce phytohormones of stimulatory action at use of methods of biotesting was established. It was shown, that bacterial culture liquid possesses high auxin, gibberellin and cytokinin activity at dilution ratio 1:10 and 1:100.
