Figure 3.

Simulated induction of leaf CO₂ uptake (A) from dark to high light with variation in (a) the concentration of pyruvate phosphate dikinase regulatory protein (PDRP), (b) the time constant for the activation of Rubisco by Rubisco activase (τ_Rubisco), and (c) the speed of stomatal opening (g _{s_ki} ); k _i is the rate constant for increase in stomatal conductance. After dark adaptation, and at time 0 above, the light intensity was raised to 1800 µmol m⁻² sec⁻¹ to initiate induction. The input parameters and 'Original values' are listed in Table 2; symbols are defined in Table 1.
