title: Molecular relationships between pseudomonas INC P-9 degradative plasmids TOL, NAH, and SAL.
abstract: We have examined the extent to which the degradative plasmids SAL, NAH, and TOL of the Inc P-9 incompatibility group share common DNA sequences. The homology we observe using 32P-labeled SAL and NAH DNA probes can be assigned to six regions of the TOL (pWWO) restriction endonuclease cleavage map. At least three of these regions are probably related to transfer and replication functions, whereas a fourth region is related to the common metacleavage pathway. Restriction endonuclease maps of the SAL and NAH plasmids are derived and the relationships between these plasmids discussed.
