From the sequence of a subcloned DNA fragment of a highly conserved plasmid of Clavibacter michiganensis subsp. sepedonicus a pair of oligonucleotides were devised for use as polymerase chain reaction primers. The primer sequences do not show significant homology with any other sequence deposited in public databases. Polymerase chain reactions carried out using this primer pair and untreated cells of all strains of C. michiganensis sepedonicus tested resulted in the amplification of a DNA fragment of about 670 base pairs. No amplification was observed when bacteria belonging to other species were submitted to polymerase chain reaction under the same conditions. The detection limit of the assay was 4 X 10(3) bacteria.

Abstract

From the sequence of a subcloned DNA fragment of a highly conserved plasmid of Clavibacter michiganensis subsp. sepedonicus a pair of oligonucleotides were devised for use as polymerase chain reaction primers. The primer sequences do not show significant homology with any other sequence deposited in public databases. Polymerase chain reactions carried out using this primer pair and untreated cells of all strains of C. michiganensis sepedonicus tested resulted in the amplification of a DNA fragment of about 670 base pairs. No amplification was observed when bacteria belonging to other species were submitted to polymerase chain reaction under the same conditions. The detection limit of the assay was 4 X 10(3) bacteria.
