Fig. 3. Reaction norms of the carbon uptake kinetics of Microcystis PCC 7806 and PCC 7941.

Fig. 3

The reaction norms show the plasticity of maximum uptake rates of (A) CO2 (Vmax,CO2,net) and (B) bicarbonate (Vmax,HCO3) and the plasticity of half-saturation constants for (C) CO2 (K1/2,CO2) and (D) bicarbonate (K1/2,HCO3), in response to acclimation to either low or high pCO2. Data points show parameter values ± SD obtained by Michaelis-Menten fits to replicated measurements of the carbon uptake kinetics (see Fig. 2 and fig. S1; n = 4 for low pCO2 and n = 3 to 4 for high pCO2). Significant differences between parameter values at low pCO2 and high pCO2 were assessed using the independent-samples t test corrected for multiple hypothesis testing (***P < 0.001; *P < 0.05; n.s., not significant). Statistical details are reported in table S3.
