Transfer and integration of chromosomal genes from Pseudomonas glycinea into Pseudomonas aeruginosa

Abstract

The plasmids FP2 and R68.45 were shown to function as chromosome-mobilizing plasmids in a series of interspecific crosses between the phytopathogen Pseudomonas glycinea and the human pathogen Pseudomonas aeruginosa. At least four of seven loci tested were transferred from P. glycinea donors to P. aeruginosa auxotrophic recipients. Transductional analysis indicates that a leu+ locus of the P. glycinea chromosome transferred is stably integrated into the P. aeruginosa chromosome.
