| lipopolysaccharides from three phytopathogenic pseudomonads. | analysis of the polysaccharide and lipid moieties of the lipopolysaccharides (lpss) of the phytopathogenic bacteria, pseudomonas amygdali and p. syringae pv. ciccaronei has demonstrated that for both bacteria, the o-chain consists of a tetrasaccharide repeating unit of three alpha-l-rhap and one terminal nonreducing alpha-d-fucp3nac. two of the rhamnosyl residues are 3-linked, the third one 2,3-linked. this structure had been previously found for the o-chains of three phytopathogenic strains of ... | 1997 | 9311153 |
| dna relatedness among the pathovars of pseudomonas syringae and description of pseudomonas tremae sp. nov. and pseudomonas cannabina sp. nov. (ex sutic and dowson 1959). | a total of 48 pathovars of pseudomonas syringae and eight related species were studied by dna-dna hybridization (s1 nuclease method) and ribotyping. the existence of nine discrete genomospecies was indicated. genomospecies 1 corresponded to p. syringae sensu stricto and included p. syringae pathovars syringae, aptata, lapsa, papulans, pisi, atrofaciens, aceris, panici, dysoxyli and japonica. genomospecies 2 included p. syringae pathovars phaseolicola, ulmi, mori, lachrymans, sesami, tabaci, mors ... | 1999 | 10319466 |
| pseudomonas frederiksbergensis sp. nov., isolated from soil at a coal gasification site. | phenotypic and genotypic characterization indicated that a group of 29 closely related phenanthrene-degrading bacteria from a coal gasification site in frederiksberg, copenhagen, denmark, belonged to the genus pseudomonas. the strains were isolated at two sampling occasions 2 years apart. the isolates were phenotypically different from any known species of the genus pseudomonas and were therefore subject to further identification. colonies were smooth and pale yellowish and did not produce pigme ... | 2000 | 11155968 |
| high-performance liquid chromatography analyses of pyoverdin siderophores differentiate among phytopathogenic fluorescent pseudomonas species. | the relationship of pyoverdins produced by 41 pathovars of pseudomonas syringae and by phytopathogenic pseudomonas species was investigated. a high-performance liquid chromatography method for analyzing the culture medium proved to be superior to isoelectric focusing for detecting pyoverdin production, for differentiating slightly different pyoverdins, and for differentiating atypical from typical fe(iii)-chelated pyoverdins. nonfluorescent strains were found in pseudomonas amygdali, pseudomonas ... | 2003 | 12571041 |
| genome sequences of pseudomonas amygdali pv. tabaci strain atcc 11528 and pv. lachrymans strain 98a-744. | certain pathovars of pseudomonas amygdali, which is newly reclassified from pseudomonas syringae by dna-dna hybridization and ribotyping, cause many serious diseases of major crop plants. herein, we present draft genome sequences of p. amygdali pv. tabaci strain atcc 11528 and p. amygdali pv. lachrymans strain 98a-744. | 2015 | 26089433 |
| whop, a genomic region associated with woody hosts in the pseudomonas syringae complex contributes to the virulence and fitness of pseudomonas savastanoi pv. savastanoi in olive plants. | bacteria from the pseudomonas syringae complex belonging to phylogroups 1 and 3 (pg1 and pg3, respectively) isolated from woody hosts share a genomic region herein referred to as whop (from woody host and pseudomonas spp.), which is absent in strains infecting herbaceous organs. in this work, we show that this region is also encoded in p. syringae pv. actinidifoliorum (pg1) and six additional members of pg3, namely, pseudomonas savastanoi pv. retacarpa, three p. syringae pathovars, pseudomonas m ... | 2017 | 28027024 |
