Lentil yield is very poor in rainfed areas of pothwar due to non-availability improved/recommended lentil varieties compatible some specific rhizobial inoculants along the site-specific production technology. Therefore, study effect inoculating with different Rhizobium strains on and quality, pot experiments were conducted greenhouse University Research Farm, Koont, Chakwal Road, Rawalpindi dur...

The growth and yield of peas cultivated on eight different soils, as well as the diversity of pea microsymbionts derived from these soils were investigated in the present study. The experimental plot was composed of soils that were transferred from different parts of Poland more than a century ago. The soils were located in direct vicinity of each other in the experimental plot. All soils exami...

Rhizobium leguminosarum bv. trifolii is a soil bacterium able to establish symbiosis with agriculturally important legumes, i.e., clover plants (Trifolium spp.). Cell surface properties of rhizobia play an essential role in their interaction with both biotic and abiotic surfaces. Physicochemical properties of bacterial cells are underpinned by the chemical composition of their envelope surround...

abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

Rhizobium leguminosarum bv. viciae is a soil α-proteobacterium that establishes a diazotrophic symbiosis with different legumes of the Fabeae tribe. The number of genome sequences from rhizobial strains available in public databases is constantly increasing, although complete, fully annotated genome structures from rhizobial genomes are scarce. In this work, we report and analyse the complete g...

In the present study, large number of rhizobial strains were isolated from chickpea, lentil and mung been nodules and twenty fast growing colonies of each host legume, were selected. A series of jar experiments were executed and three most efficient isolates of each rhizobium species were screened on the basis of their growth promoting activities under axenic conditions. Results revealed that, ...

Twenty-nine strains were isolated from two samples of the permafrost active layer Spitsbergen archipelago. The estimated number bacteria ranged 4.0⋅104 to 1.7⋅107 CFU∙g-1. As a result sequencing 16S rRNA (rrs) genes, isolates assigned 13 genera belonging phyla Actinobacteria, Proteobacteria (classes α, β, and γ), Bacteroidetes, Firmicutes. Six belonged rhizobial genus Mesorhizobium (order Rhizo...

A positive correlation has been demonstrated between the ability of Rhizobium strains to colonize acidic agar surfaces and their production of extracellular polysaccharide (EPS) in solution culture at pH 7.0. This set of experiments examined the effects of EPS on solution pH levels and Al activity, two common growth-limiting factors in acid soils. Samples of EPS from each of 20 previously acids...

Somatic antigens of Bradyrhizobium japonicum, Rhizobium sp. (Cicer arietinum) and Rhizobium sp. (Leucaena leucocephala) were prepared as standard, single-species type from cultured cells. Equal numbers of the cells of these rhizobia were then combined to obtain a mixed-rhizobial-species antigen preparation. Rabbits were immunized either with the standard, single-species type or with the mixed-r...

Rhizobial isolates that were obtained from both surface and deep soil samples in the Sahelian and Sudano-Guinean areas of Senegal (West Africa) under Acacia albida trees were compared with representative strains of known rhizobial species and genera. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of proteins was used to determine the taxonomic positions of these organisms ...
