Six plant pathogenic isolates of Pseudomonas
syringae pv. glycinea, the causal agent of bacterial
blight of Glycine max (L.) Merrill, and one isolate of
P. syringae pv. phaseolicola, the causal agent of halo
blight of Phaseolus vulgaris L., have been examined for
the presence of circular duplex deoxyribonucleic acid
(DNA)....
Five strains of the bean pathogen Pseudomonas syringae pv.
phaseolicola were analyzed for plasmid number, size, and relatedness.
Each strain contained one or two indigenous plasmids which ranged in
size from 6.8 to 151 kbp. BamHI and EcoRI restriction patterns revealed that total plasmid DNA from each strain had a...
