title: Genetic homology between independently isolated chlorobenzoate-degradative plasmids.
abstract: Two chlorobenzoate-degradative plasmids were studied by the hybridization of the restriction endonuclease-generated fragments of one plasmid after transfer to a nitrocellulose filter with nick-translated radioactive DNA of the other plasmid as a probe. Two strains harboring the 3-chlorobenzoic acid-degradative plasmids were isolated in two different parts of the world at two different times. The plasmids are now found to be closely related to each other by hybridization studies. The chlorobenzoate-degradative plasmid from Pseudomonas sp. strain B13 (termed pB13) has a 6-kilobase deletion but otherwise is homologous with previously described plasmid pAC25.
