Replicon typing of plasmids of phytopathogenic xanthomonads

Replicon types of plasmids of phytopathogenic Xanthomonads have been identified. Plasmids of Xanthomonas oryzae pathovar oryzae belonged to types RepP, RepW, RepY, RepU, and RepF1 and 50% of the plasmids of different isolates of X.o.pv.oryzae belonged to type RepP. X.c.pv.citri contained plasmids belonging to RepF1 and RepF11. Of the 19 replicon probes used, only 9 (repP, repF1, repF11, repY, repQ, repW, repX, and repU) hybridized with various plasmids of Xanthomonas.
