Growth of Synechocystis wild-type and ΔaqpZ cells under hyperosmotic conditions. (A) Growth of WT and ΔaqpZ cells on solid BG11 medium containing the indicated concentrations of NaCl or sorbitol. (B to D) Growth curves of WT (filled symbols) and ΔaqpZ (open symbols) cells growing in liquid culture. Cells were grown either in BG11 medium (B) or in BG11 medium supplemented with 0.5 M sorbitol (C) or 0.5 M NaCl (D). (E) Growth curves of WT and ΔaqpZ cells. Sorbitol (0.5 M) was added to the exponentially growing cultures at 48 h (indicated by the arrow).
