Comparison of model predictions to data at 45 minutes. (Colour) A: Dose responses predicted by the model to different doses of ABA (blue line), ACC (red line), and a combination of both (green line), 45 minutes after the stimulus. Inset: Response of AOX2 at t=45 to the dose combinations between 0.1μ M and 30μ M ABA and ACC. The markers are there to indicate the response of AOX2 to the treatments used on the right image. B: Dose responses observed in experimental measurements of stomatal closure 45 minutes after single and combined doses of 0.1μ M, 1.0μ M, 10μ M, and 20μ M ABA and ACC (n=30×3, these data were not used to re-parametrise the model).
