title: Molecular relationships of degradative plasmids determined by in situ hybridisation of their endonuclease-generated fragments.
abstract: Plasmid inter-relationships were studied by hybridisation of a radioactively labelled DNA probe to endonuclease-derived fragmentation patterns of plasmids bound to a nitrocellulose filter. The degradative plasmids SAL and NAH were found to be very closely related, but probably one did not give rise to the other by just a single deletion or insertion. Relationships between SAL and other degradative plasmids are complex; substantial homology was found with TOL and other plasmids encoding toluate dissimilation and significant homology was found with OCT.
