Cytochromes of Rhizobium [PDF]
Nature, 1958 LEGHAEMOGLOBIN, the red pigment associated with the bacteroid form of Rhizobium in effective legume root nodules, appears to be closely linked with the nitrogen fixation process1, but its connexion with Rhizobium respiration is disputed2,3. We are endeavouring to clarify the latter problem by a comparative study of respiratory pigments in several free ...

Extracellular Polysaccharides of Rhizobium [PDF]
Journal of General Microbiology, 1959 SUMMARY: The extracellular polysaccharides of seventeen strains (four species) of Rhizobium were studied chromatographically. The seven strains from lucerne (R. meliloti) produced polysaccharides which contained glucose but consistently lacked glucuronic acid. The remaining ten strains, which were isolated from pea (R.

Transfer of Rhizobium loti, Rhizobium huakuii, Rhizobium ciceri, Rhizobium mediterraneum, and Rhizobium tianshanense to Mesorhizobium gen. nov. [PDF]
International Journal of Systematic and Evolutionary Microbiology, 1997 Reasons are advanced for removal of Rhizobium ciceri, Rhizobium huakuii, Rhizobium loti, Rhizobium mediterraneum, and Rhizobium tianshanense from the genus Rhizobium and for establishment of Mesorhizobium gen. nov. for these species. A description of the genus Mesorhizobium and amended descriptions of Mesorhizobium ciceri, Mesorhizobium huakuii ...

Pectolytic enzymes in Rhizobium [PDF]
Applied and Environmental Microbiology, 1978 A sensitive pectin agar plate assay was used to demonstrate low levels of pectolytic enzymes in infective and noninfective strains of Rhizobium. The possible relation of this characteristic to legume infection is discussed.

Genetic Transformation in Rhizobium [PDF]
Journal of General Microbiology, 1969 SUMMARY: Mutants of ground nut (Rhizobium cowpea group) strain gr3 were isolated using ultraviolet radiation and N-methyl-N'-nitrosoguanidine (NTG) as mutagenic agents. An adenine-requiring mutant was used as the recipient and its wild type as the donor in transformation studies. Initially minimal medium supplemented with 2 μg. adenine/ml. was used for

Lifestyle adaptations of Rhizobium from rhizosphere to symbiosis
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Rhizobia are soil-dwelling bacteria that form symbioses with legumes and provide biologically useable nitrogen as ammonium for the host plant. High-throughput DNA sequencing has led to a rapid expansion in publication of complete genomes for
