title: Mobilization of chromosomal determinants for the polar pili of Pseudomonas aeruginosa PAO by FP plasmids.
abstract: Pseudomonas aeruginosa polar pili are determined by chromosomal genes which can be mobilized by the plasmid FP2 into a non-piliated Rec+ recipient, but not into its Rec- derivative. Matings between strains with no pili (selected by resistance to pilus-specific bacteriophages), and strains, with non-retractile pili, give rise to recombinants with retractile pili.
