Replicating plasmids for expressing genes in Synechocystis 6803. a Schematic map of three replicating plasmids with different marker genes for antibiotic-resistance selection. K Rm , C Rm , and SpecR represent the resistance genes for kanamycin, chloramphenicol, and spectinomycin, respectively. b Comparison of fluorescence from EYFP protein in three strains with different plasmids. The fluorescence data was normalized with Abs730 for cell cultures in BG11 medium with corresponding antibiotics. Error bars indicate standard deviations (n = 3)
