Growth and photosynthetic characteristics in WT, Pt43233:GFP2, and Pt43233-i1 cells determined in the seawater of altered pHs

Growth CO2	pH in the assay condition	Cell	Relative doubling rate to WT*	Relative Pmax to WT	Relative K0.5[DIC] to WT	Relative APC to WT
1%	7.5	Pt43233:GFP2	1.06 ± 0.12	0.85 ± 0.04	0.67 ± 0.08	1.12 ± 0.11
Air	7.5	Pt43233-i1	0.65 ± 0.04	0.72 ± 0.01	1.81 ± 0.24	0.40 ± 0.07
	9.0	Pt43233-i1	0.65 ± 0.04	0.72 ± 0.02	1.68 ± 0.61	0.45 ± 0.05

All values are mean ± SD of the three to five separate experiments.

^*Value was determined in the culture medium condition (pH 7.3–7.6 for 1% CO₂ and pH 7.7–8.0 for 0.04% CO₂).
