Résumé : #Xanthomonas campestris# pv. mangiferaeindicae (#Xcm#) causes mango black spot disease. We assessed the relationships among strains within pathovar mangiferaeindicae by using restriction fragment length polymorphism (RFLP) analysis. The probes were a 1,9 kb DNA fragment, containing a repetitive element cloned from #Xcm#, and two clones, which contain an avirulence gene and the #hrp# gene cluster, respectively, from #X. oryzae# pv oryzae. One hundred strains of #Xcm# were clustered after analysis with each of the three different probes into groups that were consistent with culture phenotypes or host origin. The most typical strains, found in the largest cluster, are those with white colonies and which were isolated from mango or pepper tree (in the same family as mango). Less typical strains were either yellow pigmented or were isolated from amberella, an other host of the same family of mango
