Abstract excerpt
A system which allows direct selection for curing of plasmids in Gram-negative bacteria was used to generate derivatives of Rhizobium leguminosarum VF39 cured of each of six plasmids present in this strain. Phenotypes could be correlated with the absence of five of the six plasmids. The smallest plasmid, pRleVF39a, carries genes for the production of a melanin-like pigment as has been previously reported. Plasmid...
