Characterization of Xanthomonas campestris Pathovars by rRNA Gene Restriction Patterns.
Genomic DNA of 191 strains of the family Pseudomonadaceae, including 187 strains of the genus Xanthomonas, was cleaved by EcoRI endonuclease. After hybridization of Southern transfer blots with 2-acetylamino-fluorene-labelled Escherichia coli 16+23S rRNA probe, 27 different patterns were obtained. The strains are clearly distinguishable at the genus, species, and pathovar levels. The variabilit...
متن کاملOuter Membrane Proteins and Lipopolysaccharides in Pathovars of Xanthomonas campestris.
Variations in the outer membrane proteins (OMPs) and lipopolysaccharides (LPSs) of 54 isolates belonging to 16 different pathovars of Xanthomonas campestris were characterized. OMP samples prepared by sarcosyl extraction of cell walls and LPS samples prepared by proteinase K treatment of sonicated cells were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis in the presence o...
متن کاملEpidemiology and Control of Strawberry Bacterial Angular Leaf Spot Disease Caused by Xanthomonas fragariae
Strawberry bacterial angular leaf spot (ALS) disease, caused by Xanthomonas fragariae has become increasingly problematic in the strawberry agro-industry. ALS causes small angular water-soaked lesions to develop on the abaxial leaf surface. Studies reported optimum temperature conditions for X. fragariae are 20°C and the pathogen suffers mortality above 32°C. However, at the nursery stage, dise...
متن کاملInduction of Hydrolytic Enzymes in Brassica campestris in Response to Pathovars of Xanthomonas campestris.
Inoculation of mature leaves of turnip (Brassica campestris) with the incompatible Xanthomonas campestris pv vitians resulted in the induction of beta-1,3-glucanase and chitinase/lysozyme (CHL) activity. No increase in the basal activity of beta-1,3-glucanase was observed after inoculation of leaves with heat- or rifampicin-killed X. c. vitians, Escherichia coli, or sterile water. Inoculation w...
