Figure 2From: Na+-stimulated phosphate uptake system in Synechocystis sp. PCC 6803 with Pst1 as a main transporterPhosphate uptake of cells grown in BG-11 (open circles) or Pi-limiting BG-11 for 24 h (closed circles) of wild type (A), ΔPst1 (B) and ΔPst2 (C). The concentrations of Pi used in the assay were 50 μM for all three strains. Note the difference in the scale on Y-axis for Figure 2B.Back to article page
