Regulatory elements located in the upstream region of the Rhizobium leguminosarum rosR global regulator are essential for its transcription and mRNA stability [PDF]
, 2017 Rhizobium leguminosarum bv. trifolii is a soil bacterium capable of establishing a symbiotic relationship with clover (Trifolium spp.). Previously, the rosR gene, encoding a global regulatory protein involved in motility, synthesis of cell-surface ...

chemotaxis of rhizobium phaseoli towards flavones and other related compounds [PDF]
, 1987 The formation of nitrogen-fixing nodules on leguminous plants is the result of a highly specific interaction between the host plant and the soil bacterium Rhizobium.

Bacterial genospecies that are not ecologically coherent : population genomics of Rhizobium leguminosarum [PDF]
, 2015 Biological species may remain distinct because of genetic isolation or ecological adaptation, but these two aspects do not always coincide. To establish the nature of the species boundary within a local bacterial population, we characterized a sympatric ...

Plasmid-determined Bacteriocin Production by Rhizobium leguminosarum [PDF]
Journal of General Microbiology, 1979 Summary: Bacteriocin production by 97 isolates of Rhizobium leguminosarum was investigated and two types of bacteriocins were identified and designated small and medium on the basis of their size. Three isolates appeared to carry determinants of medium bacteriocin production which were self-transmissible at frequencies of 10-1 to 10-2, suggesting the ...

Quinol Oxidase Encoded by \u3cem\u3ecyoABCD\u3c/em\u3e in \u3cem\u3eRhizobium etli\u3c/em\u3e CFN42 is Regulated by ActSR and is Crucial for Growth at Low pH or Low Iron Conditions [PDF]
, 2015 Rhizobium etli aerobically respires with several terminal oxidases. The quinol oxidase (Cyo) encoded by cyoABCD is needed for efficient adaptation to low oxygen conditions and cyo transcription is upregulated at low oxygen. This study sought to determine

Identification of rhizobial strains nodulating Egyptian grain legumes [PDF]
, 2013 The presence of apothecia in mixed species (vegetatively reproducing lichens, occasionally producing ascomata) has been interpreted as a mechanism to increase genetic variability in mostly clonal populations. However, spore viability from these apothecia

\u3cem\u3eRhizobium leguminosarum\u3c/em\u3e CFN42 Genetic Regions Encoding Lipopolysaccharide Structures Essential for Complete Nodule Development on Bean Plants [PDF]
, 1989 Eight symbiotic mutants defective in lipopolysaccharide (LPS) synthesis were isolated from Rhizobium leguminosarum biovar phaseoli CFN42. These eight strains elicited small white nodules lacking infected cells when inoculated onto bean plants.
