Two DNA fragments from Xanthomonas albilineanswere used as probes to study the molecular diversity among strains of this pathogen. Two serologically distinct groups, serovars I and II, could be differentiated by hybridization to the probes. These probes, designated 830 and 838, were cloned after subtractive DNA hybridization of common sequences of Xanthomonas campestrispv. vasculorumfrom a serovar I strain of X. albilineans.They did not hybridize to the DNA of several other xanthomonads or to sugarcane DNA under the conditions of hybridization used. Faint bands were observed upon hybridization of probe 830 with one strain of X. campestrispv. phaseoli.The same banding patterns were obtained with a strain of X. albilineansfrom Burkina Faso and the serovar II strains of Mauritius. The serovar I strains from Mauritius and two other strains each from Reunion and South Africa had similar pattern. |
