(A,B) Images are a merge of phase contrast and GFP channel. 26 × 39 μm fields of view are shown. Scale bar represent 5 μm. Representative replicates are shown. Three independent experiments were performed. (C) Survival assay performed with ON cultures of F. novicida U112 pFNMB1 msfgfp and F. novicida U112 pFNMB2 msfgfp plated on ampicillin and ampicillin/kanamycin plates. Three independent experiments were performed. (D) Digestion of pFNMB1 msfgfp with SacI and SpeI restriction enzymes. (E) Digestion of pFNMB2 msfgfp with SacI and SpeI restriction enzymes. (D,E) Plasmids were passaged in F. novicida for 4 days before being transformed into E. coli . Controls were isolated directly from E. coli . Representative replicates are shown. Three independent experiments were performed.
