Rhizobia: from saprophytes to endosymbionts [PDF]
Nature Reviews Microbiology, 2018 Rhizobia are some of the best-studied plant microbiota. These oligotrophic Alphaproteobacteria or Betaproteobacteria form symbioses with their legume hosts. Rhizobia must exist in soil and compete with other members of the microbiota before infecting legumes and forming N2-fixing bacteroids.

The interaction between rhizobia and their legume host plants conduces to the formation of specialized root organs called nodules where rhizobia differentiate into bacteroids which fix atmospheric nitrogen to the benefit of the plant. This beneficial symbiosis is of importance in the context of sustainable agriculture as legumes do not require the ...

Characterization of rhizobia fromLeucaena
World Journal of Microbiology & Biotechnology, 1992Seventy-six rhizobia were isolated from the nodules ofLeucaena plants of various genotypes growing in a wide range of soil types and climatic regions. The isolates were fast-growing and acid-producing. In establishing a serological grouping for the isolates, the intrinsic antibiotic resistance (IAR) patterns to low concentrations of eight antibiotics ...

Sensitivity of Rhizobia to vanillin
Folia Microbiologica, 1974The sensitivity of Rhizobia isolated from pea, fenugreek, gram, cowpea, urid andRhizobium meliloti, Rhizobium trifolii andRhizobium japonicum was studied in asparagine-mannitol, salt-mannitol and salt media. It was observed that Rhizobia from gram were most resistant.Rhizobium japonicum was found to be resistant up to 50 mg vanillin/100 ml.

Phytoremediation Using Rhizobia
2015The use of plants to clean up polluted sites, named phytoremediation, is an attractive methodology for the cleanup of metals and other soil contaminants. While some plants can hyperaccumulate metals from the environment or break down diverse organic contaminants, they typically do not produce a large amount of biomass, and many other plants are unable ...

16S rRNA sequence analyses have been used to infer the phylogenetic relationships among rhizobial species by comparison with results obtained from sequences of two alternative loci. We consider the possibility of whether a biological species approach might be useful in defining species limits in the rhizobia.
