Physiological responses of cells of Synechocystis PCC6803 to aeration for up to 6 h with CO₂-free air. A, V_max of net O₂ evolution. The mean ± sd of three separate experiments are shown. B, Pooled average increase in ndhF3, sbtA, and cmpA transcripts replotted from the RT-PCR experiment shown in Figure 4 (black circles) and the rates of Ci uptake (white squares) or net O₂ evolution (white triangles) supported by 20 μm Ci in the assay medium replotted from the drawdown experiments shown in Figure 2B.
