The location of genes in the vicinity of the major FP2 origin on the chromosome of Pseudomonas aeruginosa PAO has been revised. The markers hisI (a transduction group of histidine biosynthetic genes) and pru (a gene cluster encoding proline utilization functions) were located in the 90 to 95/0 min chromosome region by a series of plate matings mediated by R68.45. Three-factor-crosses using this plasmid established the following marker order: pur-67 pru hisI/cys-59 proB ilvB/C. Genetic evidence is presented to confirm the previous observations that FP2 can mobilize the chromosome from at least two origins near proB and in both directions. Thus, when markers in this chromosome region are analyzed by FP2 crosses only, the mapping data may be difficult to interpret. This complication can be overcome by the use of R68.45 and Tfr (transposon-facilitated recombination) or Hfr donors.
