Extracellular Polysaccharides of Rhizobium [PDF]
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.

Cytochromes of Rhizobium [PDF]
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 ...

Pectolytic enzymes in Rhizobium [PDF]
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 Characterization and Symbiotic Performance of Soybean Rhizobia Under Cold and Water-Deficient Conditions in Poland [PDF]
Soybeans have been cultivated in Poland for more than 140 years. However, Poland’s cold and water-deficient climatic conditions hinder soybean cultivation.

Screening and Validation of Rhizobial Strains for Improved Lentil Growth [PDF]
Lentil is a nutritionally valuable legume crop, rich in protein, carbohydrates, amino acids, and vitamins, and is also used as green manure. Symbiotic nitrogen fixation (SNF) plays a crucial role in lentil growth and development, yet there is limited ...

The ubiquitous second messenger c-di-GMP is well-known for its role in biofilm formation and host adaptation of pathogens, whereas it is less investigated in mutualistic symbioses. Here, we reveal a cocktail of eight functional diguanylate cyclases (DGCs)

Transfer of Rhizobium loti, Rhizobium huakuii, Rhizobium ciceri, Rhizobium mediterraneum, and Rhizobium tianshanense to Mesorhizobium gen. nov. [PDF]
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 ...

Modulation of Symbiotic Compatibility by Rhizobial Zinc Starvation Machinery
Pathogenic bacteria need high-affinity zinc uptake systems to counteract the nutritional immunity exerted by infected hosts. However, our understanding of zinc homeostasis in mutualistic systems such as the rhizobium-legume symbiosis is limited. Here, we

Genetic Transformation in Rhizobium [PDF]
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
