Strains PG401 (amyE::PcomG-lacZ-gfp, PcomG-comK, ΔmecA) and PG401-Tn4 (amyE::PcomG-lacZ-gfp, PcomG-comK, ΔmecA, ykyB:Tn) were grown on nutrient agar plates (A) or competence medium plates (B) supplemented with X-gal. Cells from plates were imaged by fluorescent light microscopy. Insets show related phase contrast images and arbitrary GFP colour intensity scales. Pictures and microscopy images were taken after overnight incubation at 37°C.
