The effect of salt concentrations on the growth of Synechocystis. The strains WT, WT_M, ΔGGPS, ΔGGPS_M, ΔCS and ΔCS_M were grown to OD730 = 1.0, after which 5 µl of WT, WT_M, ΔGGPS and ΔGGPS_M were transferred to a plate with a linear gradient of NaCl with a maximum salt concentration of 1 M; in addition, 5 µl of ΔCS and ΔCS_M was grown on a plate with a linear gradient with a maximum salt concentration of 0.5 M. The plates were incubated for 12 days at 30 °C. Red rectangles emphasize differences in salt resistance between corresponding strains (i.e., the same genetic background, but with and without the mannitol cassette)
