Abstract

The genomic island pKLC102 first detected in Pseudomonas aeruginosa clone C strains can cross species barriers and exhibits the highest mobilization rate of a genomic island known to date. Homologous genomic islands of 81-108 kb in size were identified in the completely sequenced P. aeruginosa strains PA7, PA14, 2192, C3719 and PACS2, but not in strains PAO1 and LES. All pKLC102-like genomic islands are integrated in chromosomal tRNA(Lys) genes and share a syntenic set of more than 70 homologous ORFs, part of which are related to DNA replication or mobility genes. The conserved backbone has predilection sites for the uptake of island-specific gene cassettes. A major difference between the islands is the organization of the origin of replication oriV.
