| diazotrophic burkholderia species isolated from the amazon region exhibit phenotypical, functional and genetic diversity. | forty-eight burkholderia isolates from different land use systems in the amazon region were compared to type strains of burkholderia species for phenotypic and functional characteristics that can be used to promote plant growth. most of these isolates (n=46) were obtained by using siratro (macroptilium atropurpureum - 44) and common bean (phaseolus vulgaris - 2) as the trap plant species; two isolates were obtained from nodules collected in the field from indigofera suffruticosa and pithecellobi ... | 2012 | 22609342 |
| efficient nitrogen-fixing rhizobium strains isolated from amazonian soils are highly tolerant to acidity and aluminium. | one of the most cultivated and consumed vegetables in brazil is the common bean, phaseolus vulgaris l. the symbiosis of this plant species with nitrogen-fixing bacteria that are adapted to the stresses commonly found in tropical soils can increase production. the aim of this study was to evaluate the symbiotic effectiveness of bacterial strains from soils under different land uses in the amazon region. further, rhizobia tolerance to acidity and aluminium and the involvement of some possible phys ... | 2012 | 22806016 |
