Two modes of loss of the Tol function from Pseudomonas putida mt-2

Mol Gen Genet. 1977 Jul 20;154(2):203-4. doi: 10.1007/BF00330838.


Some of a set of independently arising Tol- (non toluate-utilising) derivatives of Pseudomonas putida mt-2 have lost the unique plasmid present in the parent strain. In others this plasmid has suffered a deletion of a specific region of about 27 Md.
