Introduction of Rhizobium into Soils
1988Preliminary results of the common experiment designed to investigate gene transfer in the environment between introduced Rhizobium leguminosarum bv viceae RSM2004 and native strains of bacteria are reported. They show an exclusive nodulation of the pea by wild type strains, which casts some doubt on the successful introduction of the strain.

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

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 ...

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 ...

A plant flavone, luteolin, induces expression of Rhizobium meliloti nodulation genes.
Science, 1986The symbiotic interaction of Rhizobium meliloti and alfalfa results in the formation of nitrogen-fixing root nodules. Rhizobium meliloti nodABC genes are required for the early host responses of cortical cell divisions and root hair curling.

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 Nodulation Factors in Perspective
1997Since the discovery of Nod factors (NFs) six years ago (Lerouge et al 1990), many studies have concentrated on the role of the various rhizobial nod genes in the control of NF synthesis, the diversity of NF structures, and the various types of responses that NFs elicit in plants.
