During 2010, black rot symptoms were observed in oilseed rape plants grown in a commercial plot in Serbia. Ten bacterial isolates obtained from diseased plants, and identified as Xanthomonas campestris pv. campestris (Xcc) based on pathogenicity, physiological and biochemical tests, PTA-ELISA and 16S rDNA sequences analysis, were investigated in detail. Strains were characterized by comparing them by rep-PCR fingerprints using ERIC and (GTG)5 primers. The 16S rDNA sequences of strains TUr1 and TUr6 were deposited in GenBank under accession Nos. KF057196 and KF057197, respectively. Phylogenetic analysis of the 16S regions showed high similarity level for oilseed rape representative strains and Xcc strains of different origin isolated from kale, cabbage and broccoli.
