Abstract	The integron platform and the gene cassette arrays of 34 Xanthomonas arboricola pv. juglandis and of 47 Xanthomonas arboricola pv. pruni strains isolated from different geographical areas were screened to check their variability. Genetic variability of the strains was also tested by means of BOX-PCR. For two representative strains of the two pathovars, the integrase gene intI and part of the flanking gene ilvD were also cloned and sequenced. Whereas X. a. pv. pruni strains did not show relevant variability, six X. a. pv. juglandis strains isolated in Australia showed some differences in the gene sequences. The CLUSTALW algorithm indicated that the majority of the X. a. pv. juglandis strains are closely related to X. a. pv. pruni, whereas the X. a. pv. juglandis strains isolated in Australia were more similar to Xanthomonas hortorum pv. pelargonii. Similarly, the gene cassette array pattern of the Australian strains, as well as that of the oldest strain maintained in culture, was different from the other strains. Also, three X. a. pv. pruni strains showed a different cassette array pattern when compared with the majority of other strains but no relationships with geographical area of isolation or host plant was revealed. This study confirmed that in addition to species, integrons may generate diversity also within two X. arboricola pathovars.
