Concentration and time course dependence of two structurally related plant flavonoids naringenin and quercetin on the nodABC gene transcriptional activity (as reporter gene nodC-lacZ activity) in Rh. leguminiosarum bv. vicae strain D923 and respective growth, nodulation and nitrogen fixing responses of plant host (garden pea) to inoculation with pre-induced strains were studied. Naringenin was ...

The genetic structure of a population of nonsymbiotic Rhizobium leguminosarum strains was determined by the electrophoretic mobilities of eight metabolic enzymes. Nonsymbiotic strains were isolated from the rhizosphere of bean plants and characterized by growth on differential media and at different temperatures, intrinsic antibiotic resistance, the lack of homology to a nifH probe, and their i...

abstractin order to investigate the effects of the inoculation with p. putida, r. leguminosarum bv. phaseoli and f. mosseae on yield and nutrient uptake of common bean (phaseolus vulgaris l.), a greenhouse experiment in a completely randomized factorial design with 3 treatment including a: microorganism in four level (no inoculation, p. putida, f. mosseae and mix inoculation of fungi and bacter...

The free-living legume symbiont Rhizobium leguminosarum is of significant economic value because of its ability to provide fixed nitrogen to globally important leguminous food crops, such as peas and lentils. Discovery based research into the genetics and physiology of R. leguminosarum provides the foundational knowledge necessary for understanding the bacterium's complex lifestyle, necessary f...
