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

The inability to predict why legumes develop poorly and fix little nitrogen in fertile soil containing Rhizobium strains active in the symbiosis frequently results from the lack of knowledge of the ecology of the root-nodule bacteria. If the appropriate host and an effective bacterium are both present in fertile land, there ought to be active nitrogen ...

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 ...

Symbiosis between Rhizobium bacteria and legumes leads to the formation of the root nodule. The endosymbiotic bacteria reside in polyploid host cells as membrane-surrounded vesicles where they reduce atmospheric nitrogen to support plant growth by ...

Rhizobia are gram-negative bacteria with two distinct habitats: the soil rhizosphere in which they have a saprophytic and, usually, aerobic life and a plant ecological niche, the legume nodule, which constitutes a microoxic environment compatible with the operation of the nitrogen reducing enzyme nitrogenase.

Plasmid replicons of Rhizobium
Biochemical Society Transactions, 2005Rhizobium spp. are found in soil. They are both free-living and found symbiotically associated with the nodules of leguminous plants. Traditionally, studies have focused on the association of these organisms with plants in nitrogen-fixing nodules, since this is regarded as the most important role of these bacteria in the environment. Rhizobium sp.
