| 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 |
