| burkholderia spp. are the most competitive symbionts of mimosa, particularly under n-limited conditions. | bacteria isolated from mimosa nodules in taiwan, papua new guinea, mexico and puerto rico were identified as belonging to either the alpha- or beta-proteobacteria. the beta-proteobacterial burkholderia and cupriavidus strains formed effective symbioses with the common invasive species mimosa diplotricha, m. pigra and m. pudica, but the alpha-proteobacterial rhizobium etli and r. tropici strains produced a range of symbiotic phenotypes from no nodulation through ineffective to effective nodulatio ... | 2009 | 19040456 |
| genetic diversity of mimosa pudica rhizobial symbionts in soils of french guiana: investigating the origin and diversity of burkholderia phymatum and other beta-rhizobia. | the genetic diversity of 221 mimosa pudica bacterial symbionts trapped from eight soils from diverse environments in french guiana was assessed by 16s rrna pcr-rflp, rep-pcr fingerprints, as well as by phylogenies of their 16s rrna and reca housekeeping genes, and by their nifh, noda and nodc symbiotic genes. interestingly, we found a large diversity of beta-rhizobia, with burkholderia phymatum and burkholderia tuberum being the most frequent and diverse symbiotic species. other species were als ... | 2011 | 22093060 |
| burkholderia mimosarum sp. nov., isolated from root nodules of mimosa spp. from taiwan and south america. | fourteen strains were isolated from nitrogen-fixing nodules on the roots of plants of the genus mimosa growing in taiwan, brazil and venezuela. on the basis of 16s rrna gene sequence similarities, all of the strains were previously shown to be closely related to each other and to belong to the genus burkholderia. a polyphasic approach, including dna-dna reassociation, whole-cell protein analysis, fatty acid methyl ester analysis and extensive biochemical characterization, was used to clarify the ... | 2006 | 16902019 |
| burkholderia heleia sp. nov., a nitrogen-fixing bacterium isolated from an aquatic plant, eleocharis dulcis, that grows in highly acidic swamps in actual acid sulfate soil areas of vietnam. | nitrogen-fixing bacteria, strains sa41(t), sa42 and sa53, were isolated from an aquatic plant, eleocharis dulcis, that grows in highly acidic swamps (ph 2-4) in actual acid sulfate soil areas of vietnam. the isolates were gram-negative, aerobic, non-spore-forming, rod-shaped bacteria, having a cell width of 0.6-0.7 microm and a length of 1.5-1.7 microm. they showed good growth between ph 3.0 and 7.0, and between 17 and 37 degrees c. the organisms contained ubiquinone q-8 as the predominant isopr ... | 2010 | 19666801 |
