Plasmid-mediated catabolism of dicamba by Pseudomonas species strain PXM

Pseudomonas species strain PXM, which is able to use dicamba (3,6-dichloro-2-methoxybenzoic acid; CAS 1918-00-9, Banvel) as its sole carbon source for growth, has been isolated. The catabolism of dicamba and some of its putative metabolic descendants correlates with the presence of a large and unstable plasmid.
