Mobilization of chromosomal determinants for the polar pili of Pseudomonas aeruginosa PAO by FP plasmids

Canadian Journal of Microbiology

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.
