Xad . Although the closest match for all three strains is X. axonopodis , the 16S sequence is too conserved to be used for identification to the species level. Numerous other Xanthomonas spp. (i.e., X. campestris , X. vasicola , X. gardneri , and
Bacterial spot of tomato is caused by as many as four species of Xanthomonas : X. euvesicatoria , X. vesicatoria , X. perforans , and X. gardneri ( Jones et al., 2000 , 2005 ); the former three species were previously named X. campestris
Bacterial spot is a major disease of tomato ( Solanum lycopersicum ) in Florida and worldwide ( Jones, 1991 ; Jones et al., 2004 ). The disease is associated with four species of Xanthomonas : X. euvesicatoria , X. vesicatoria , X. perforans
