PCR analysis of the largest tandem segmental duplicons. (a) A schematic illustration of the largest duplicons, with PCR primers used for genotyping labeled. (b) A representative gel for strains that do not carry the largest duplication. (c) A representative gel for strains carrying the largest duplication. Lane 1 shows PCR product using primers 319L and 319OR; lane 2 shows PCR product using primers 319L and 319IR; lane 3 shows PCR product using primers DupOL and DupIR; lane 4 shows PCR product using primers DupIL and DupIR; and lane 5 shows PCR product using primers DupIL and DupOR.
