| prevalence of burkholderia sp. nodule symbionts on four mimosoid legumes from barro colorado island, panama. | sequences of 16s rrna and partial 23s rrna genes and pcr assays with genotype-specific primers indicated that bacteria in the genus burkholderia were the predominant root nodule symbionts for four mimosoid legumes (mimosa pigra, m. casta, m. pudica, and abarema macradenia) on barro colorado island, panama. among 51 isolates from these and a fifth mimosoid host (pithecellobium hymenaeafolium), 44 were burkholderia strains while the rest were placed in rhizobium, mesorhizobium, or bradyrhizobium. ... | 2005 | 15709366 |
| nodulation of cyclopia spp. (leguminosae, papilionoideae) by burkholderia tuberum. | species of the genus burkholderia, from the betaproteobacteria, have been isolated from legume nodules, but so far they have only been shown to form symbioses with species of mimosa, sub-family mimosoideae. this work investigates whether burkholderia tuberum strains stm678 (isolated from aspalathus carnosa) and dus833 (from aspalathus callosa) can nodulate species of the south african endemic papilionoid genera cyclopia (tribe podalyrieae) and aspalathus (crotalarieae) as well as the promiscuous ... | 2007 | 17881339 |
| burkholderia tuberum sp. nov. and burkholderia phymatum sp. nov., nodulate the roots of tropical legumes. | the taxonomic status of five root nodule isolates from tropical legumes was determined using a polyphasic taxonomic approach. two isolates were identified as b. caribensis, an organism originally isolated from soil in martinique (the french west indies). one isolate was identified as burkholderia cepacia genomovar vi, a b. cepacia complex genomovar thus far only isolated from sputum of cystic fibrosis patients. the remaining two isolates were identified as novel burkholderia species for which we ... | 2002 | 12583710 |
| 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 |
| diversity of bacteria associated with bursaphelenchus xylophilus and other nematodes isolated from pinus pinaster trees with pine wilt disease. | the pinewood nematode (pwn), bursaphelenchus xylophilus, has been thought to be the only causal agent of pine wilt disease (pwd), however, since bacteria have been suggested to play a role in pwd, it is important to know the diversity of the microbial community associated to it. this study aimed to assess the microbial community associated with b. xylophilus and with other nematodes isolated from pine trees, pinus pinaster, with pwd from three different affected forest areas in portugal. one hun ... | 2010 | 21151611 |
| mixotrophic metabolism in burkholderia kururiensis subsp. thiooxydans subsp. nov., a facultative chemolithoautotrophic thiosulfate oxidizing bacterium isolated from rhizosphere soil and proposal for classification of the type strain of burkholderia kururiensis as burkholderia kururiensis subsp. kururiensis subsp. nov. | a thiosulfate-oxidizing facultative chemolithoautotrophic burkholderia sp. strain atsb13(t) was previously isolated from rhizosphere soil of tobacco plant. strain atsb13(t) was aerobic, gram-staining-negative, rod shaped and motile by means of sub-terminal flagellum. strain atsb13(t) exhibited mixotrophic growth in a medium containing thiosulfate plus acetate. a phylogenetic study based on 16s rrna gene sequence analysis indicated that strain atsb13(t) was most closely related to burkholderia ku ... | 2009 | 19841903 |
| proof that burkholderia strains form effective symbioses with legumes: a study of novel mimosa-nodulating strains from south america. | twenty mimosa-nodulating bacterial strains from brazil and venezuela, together with eight reference mimosa-nodulating rhizobial strains and two other beta-rhizobial strains, were examined by amplified rrna gene restriction analysis. they fell into 16 patterns and formed a single cluster together with the known beta-rhizobia, burkholderia caribensis, burkholderia phymatum, and burkholderia tuberum. the 16s rrna gene sequences of 15 of the 20 strains were determined, and all were shown to belong t ... | 2005 | 16269788 |
