| diversity analysis of diazotrophic bacteria associated with the roots of tea (camellia sinensis (l.) o. kuntze). | the diversity elucidation by amplified ribosomal dna restriction analysis and 16s rdna sequencing of 96 associative diazotrophs, isolated from the feeder roots of tea on enriched nitrogen-free semisolid media, revealed the predominance of gram-positive over gram-negative bacteria within the kangra valley in himachal pradesh, india. the gram-positive bacteria observed belong to two taxonomic groupings; firmicutes, including the genera bacillus and paenibacillus; and actinobacteria, represented by ... | 2011 | 21715960 |
| tolerance of mesorhizobium type strains to different environmental stresses. | the symbiosis between rhizobia and legumes is affected by different environmental conditions. our aims were to evaluate stress tolerance of mesorhizobium species and investigate species-specific stress response mechanisms. tolerance of mesorhizobium type strains to temperature, salt and ph stress was evaluated. mesorhizobium thiogangeticum showed highest growth with 1.5% nacl and mesorhizobium ciceri at ph 5. mesorhizobium plurifarium showed higher growth at 37°c. sds-page analysis revealed chan ... | 2010 | 21152981 |
| characterization of strains unlike mesorhizobium loti that nodulate lotus spp. in saline soils of granada, spain. | lotus species are forage legumes with potential as pastures in low-fertility and environmentally constrained soils, owing to their high persistence and yield under those conditions. the aim of this work was the characterization of phenetic and genetic diversity of salt-tolerant bacteria able to establish efficient symbiosis with lotus spp. a total of 180 isolates able to nodulate lotus corniculatus and lotus tenuis from two locations in granada, spain, were characterized. molecular identificatio ... | 2010 | 20435777 |
| mesorhizobium albiziae sp. nov., a novel bacterium that nodulates albizia kalkora in a subtropical region of china. | a novel mesorhizobium group associated with albizia kalkora [wang et al. (2006), syst appl microbiol 29, 502-517] was further characterized. the seven strains in this group showed similar protein patterns and were different from defined mesorhizobium species in sds-page of whole-cell proteins. the representative strain ccbau 61158(t) formed a novel mesorhizobium lineage in phylogenetic analyses of 16s rrna, atpd, glnii and nifh genes. however, its nodc gene sequence was more similar to that of r ... | 2007 | 17551028 |
