O polysaccharides (OPS) of the lipopolysaccharides (LPS) of Pseudomonas syringae pathovar tomato GSPB 483 and pathovar maculicola IMV 381 were studied by 1H-NMR and 13C-NMR spectroscopy, including two-dimensional COSY, rotating-frame NOE spectroscopy (ROESY), and H-detected 1H,13C heteronuclear multiple-quantum coherence (HMQC) experiments. The OPS from(More)
Transfer of plasmid pRD1 from Escherichia coli K12J62-1 to phytopathogenic bacteria, Agrobacterium tumefaciens, Xanthomonas beticola and Erwinia carotovora subsp. carotovora caused changes in conjugant properties not determined by the plasmid and the emergence of the properties not present in the parent strains. Clones have been obtained with intermediate(More)
The paper deals with a comparative analysis of the serological and ecological properties of Pseudomonas syringae pv. atrofaciens strains from the collections of microbial cultures at the Malkov Institute for Plant Genetic Resources and Zabolotny Institute of Microbiology and Virology. All of the strains from the Bulgarian collection, except for one, fall(More)
Pseudomonas syringae pv. maculicola dissociants producing colonies of different morphotypes were found to possess similar biochemical and serological properties but different virulence to the host plant. The heterogeneous extracellular and intracellular lipopolysaccharide–protein complexes of the dissociants differed in their chemical composition and(More)
Polyamine profiles of 91 pectolytic and other plant-associated strains from 30 taxa of the Enterobacteriaceae were obtained by gradient high performance liquid chromatography (HPLC). Pectobacterium carotovorum, basonym Erwinia carotovora, contained a high amount of putrescine and less diaminopropane. Diaminopropane was absent in Pectobacterium chrysanthemi,(More)
