FIG 4

Plasmid stability of the pLeptin-ThyA construct in LRΔthyA::rpoB(H488R). Plasmid stability is represented by the percentage of cells from plain MRS broth that retained pLeptin-ThyA, pCtl-ThyA, or pLeptin over the course of ∼100 generations without antibiotic in the medium. (Inset) Plasmid stability of pLeptin-ThyA, pCtl-ThyA, or pLeptin from mMRS without thymidine (no beef extract) (P < 0.01, Tukey’s HSD). The results shown are averages from three independent experiments ± standard error. Different letters indicate statistical differences between the respective treatment groups.
