Genetic markers for Xanthomonas oryzae pv.oryzae, primers for the markers, and method for detecting and discriminating Xanthomonas oryzae pv.oryzae

摘要

PURPOSE: A gene marker of Xanthomonas oryzae pv. oryzae causing bacterial leaf blight is provided to quickly and accurately determine gene polymorphism. CONSTITUTION: A gene marker of Xanthomonas oryzae pv. oryzae contains a base sequence of sequence number 1, 2, or 3. A primer pair has sequence numbers 4 and 5 which are specific to the base of sequence number 1. A primer pair has sequence numbers 6 and 7 which are specific to the base of sequence number 2. A primer pair has sequence numbers 8 and 9 which are specific to the base of sequence number 3. A method for determining infection of bacterial leaf blight comprises: a step of preparing rice plant sample; a step of performing PCR using the primer; and a step of confirming PCR product by electrophoresis.
