To develop a rapid and reliable detection and identification method for Clavibacter michiganensis subsp. sepedonicus and C. michiganensis subsp. michiganensis, two biotinylated probes and derived primer sets were evaluated for specificity using a large number of bacterial strains. Detection in dot blot analysis using the Diagen probe against C. michiganensis subsp. sepedonicus was possible with all 32 C. michiganensis subsp. sepedonicus strains tested. Cross-hybridization occurred with all nine C. michiganensis subsp. insidiosus strains tested. No hybridization occurred with any of 54 other related and unrelated bacterial strains including C. michiganensis subsp. michiganensis, C. michiganensis subsp. nebraskensis, C. michiganensis subsp. tessellarius, C. iranicus, C. rathayi, and C. tritici and potato saprophytes. Hybridization of the MIC 1 probe against C. michiganensis subsp. michiganensis was obtained with 22 out of 24 C. michiganensis subsp. michiganensis strains. A weak hybridization signal occurred only with two strains of C. michiganensis subsp. insidiosns. No hybridization occurred with any of the 71 other related and unrelated bacterial strains tested including tomato saprophytes. Restriction fragment length polymorphisms detected with the Diagen probe allowed differentiation between C. michiganensis subsp. sepedonicus and the related C. michiganensis subsp. insidiosus. Restriction fragment length polymorphism analysis using the MIC 1 probe and BamH1 showed at least two groups of patterns within C. michiganensis subsp. michiganensis. By using a primer set derived from the Diagen probe, a DNA sequence could be amplified with all C. michiganensis subsp. sepedonicus strains tested. Only the nontarget organism C. michiganensis subsp. insidiosus yielded a similar polymerase chain reaction product. Restriction enzyme analysis of the polymerase chain reaction product enabled rapid distinction between the subspecies. With a CMM primer set derived from the MIC 1 probe a DNA sequence was amplified from the same 22 out of 24 C. michiganensis subsp. michiganensis strains that showed hybridization with the MIC 1 probe. The polymerase chain reaction product could be verified by restriction enzyme analysis. The Diagen and MIC 1 probes and derived primer sets were shown to be useful for the detection and identification of C. michiganensis subsp. sepedonicus and C. michiganensis subsp. michiganensis. The MIC 1 probe, however, failed to detect two strains of the latter subspecies.Key words: biotin, PCR, REA, potato bacterial ring rot, bacterial canker of tomato, RFLP, Clavibacter michiganensis subsp. insidiosus.
