Prediction of the low-temperature gating of CBF expression closely matches experimental data if cold is assumed to increase the level of the LHY protein. Simulations for the model in which CBF expression is controlled by LHY, TOC1 and EC were scaled and plotted against data for the low-temperature induction of CBF2 expression, gathered from Fowler et al. (2005; closed circles) and the cold induction of CBF3 (Dong et al., 2011). Low temperature was simulated by increasing C_LHY (open circles) or C_CBF3 ^m (closed triangles, to simulate a cold signal arriving directly at the CBF locus) five-fold at the indicated times after subjective dawn.
