| characterization of symbiotic and endophytic bacteria isolated from root nodules of herbaceous legumes grown in qinghai-tibet plateau and in other zones of china. | qinghai-tibet plateau is the highest place in the world and the environment in that plateau is hard for animals and plants, with low temperature, low concentration of oxygen and high solar radiation. in this study, 61 root nodule isolates from vicia, oxytropis, medicago, melilotus and onobrychis species grown in qinghai-tibet plateau and in loess plateau were comparatively characterized. based upon the results of numerical taxonomy, ardra, aflp, dna-dna hybridization and 16s rdna sequencing, the ... | 2007 | 17541555 |
| rhizobial resource associated with epidemic legumes in tibet. | a total of 128 bacterial test strains originated from astragalus, caragana, gueldenstaedtia, medicago, melilotus, oxytropis, trifolium, and vicia grown in tibet were characterized phenotypically and genomically. based upon the consensus of grouping results, they were identified as 16 putative species. twenty-five test strains belonging to seven putative species of agrobacterium, bradyrhizobium, and rhizobium might be nonsymbiotic bacteria and the remaining 103 test strains were symbiotic bacteri ... | 2009 | 18568286 |
| [analysis of dna homology and 16s rdna sequence of rhizobia, a new phenotypic subgroup, isolated from xizang autonomous region of china]. | based on the studies of numerical taxonomy, the seven rhizobial strains isolated from the root nodules of leguminous plants trigonella spp. and astragalus spp. growing in the xizang autonomous region of china constituted a new phenotypic subgroup, where wide phenotypic and genotypic diversity among legume crops had been reported due to complex terrain and various climate. the new phenotypic subgroup were further identified to clarify its taxonomic position by dna homology analysis and 16s rdna g ... | 2006 | 16579480 |
| rhizobium tubonense sp. nov., isolated from root nodules of oxytropis glabra. | four rhizobial strains, designated ccbau 85046(t), ccbau 85051, ccbau 85048 and ccbau 85049, isolated from root nodules of oxytropis glabra grown in tibet, china, were previously defined, using amplified 16s rrna gene restriction analysis, as a novel group within the genus rhizobium. to clarify their taxonomic position, these strains were further analysed and compared with reference strains of related bacteria using a polyphasic approach. the 16s rrna gene analysis showed that the four isolates ... | 2011 | 20382797 |
| rhizobium tibeticum sp. nov., a symbiotic bacterium isolated from trigonella archiducis-nicolai (sirj.) vassilcz. | isolated from root nodules of trigonella archiducis-nicolai (sirj.) vassilcz. grown in tibet, china, cells of the bacterial strains ccbau 85039(t) and ccbau 85027 were gram-negative, aerobic, motile, non-spore-forming rods that formed colonies that were semi-translucent and opalescent on yeast extract-mannitol agar. in numerical taxonomy, sds-page analysis of whole-cell proteins and dna-dna hybridization, the two strains were very similar and were different from reference strains of defined rhiz ... | 2009 | 19643889 |
