[F1ANNEX I U.K. TEST SCHEME FOR DIAGNOSIS, DETECTION AND IDENTIFICATION OF THE RING ROT BACTERIUM, CLAVIBACTER MICHIGANENSIS (Smith) Davis et al. ssp. SEPEDONICUS (Spieckermann et Kotthoff) Davis et al. SCOPE OF THE TEST SCHEME

Appendix 6 Validated PCR protocol and reagents

1. Multiplex PCR protocol with internal PCR control (Pastrik, 2000) U.K.

1.4. Restriction enzyme analysis of amplicon. U.K.

PCR products amplified from C. m. subsp. sepedonicus DNA produce a distinctive restriction fragment length polymorphism with enzyme Bgl II after incubation at 37 °C for 30 minutes. The restriction fragments obtained from C. m. subsp. sepedonicus -specific fragment are 282 bp and 220 bp in size.]
