Growth depression of Serratia marcescens by plasmids that belong to incompatibility group P.
Microbios - 1 Jan 1990
Platt D J, Chesham J S
Abstract excerpt
The IncP plasmids R702, RP4 and derivative plasmids including RP4::Mu cts were studied in two pigmented strains of Serratia marcescens. Maintenance of these plasmids resulted in reduced pigmentation and the growth rate of colonies was slower than the plasmid-free parent organisms. DNA inserts and deletions in RP4 altered both the pigmentation phenotype and growth rate of S. marcescens transconjugants and was...
