Growth of the generated Synechocystis strains harboring the sYFP2 expression cassette in the A) chromosome or in the B) native plasmids, in reference to the WT and the control strains (*). The cultivations were carried out in Erlenmeyer flasks, at 30 °C under constant light of 50 μmol photons m⁻² s⁻¹ and 1% CO₂ atmosphere, and the growth was measured as OD₇₅₀ increase over a period of seven days from induction. The mean and standard deviation at each measurement point have been calculated from three independent cultivations
