DNA restriction fragment length polymorphisms (RFLPs) were evaluated as a tool for distinguishing among three races of Xanthomonas campestris pv vasculorum (Xcv), causal agent of gumming disease of sugar cane. Two probes, pUFT-1 and pUFT-11, derived from X.c. pv citri, and six restriction enzymes, EcoR I, Hind III, Bgl II, Xho I, Bam H I and Ava I, were used. RFLPs were detected among the three races with bands specific to race 2, after digestion with enzyme Ava I and hybridization with probe pUFT-1. RFLPs were not found with the other enzyme-probe combinations. Races 1 and 3 could not be distinguished. The results indicated that the three races were genetically closely related and that, to detect small variations in their chromosomal DNA, probes derived from a genomic DNA library of Xcv will have probably to be used. | |
