A Circadian Clock-Regulated Toggle Switch Explains AtGRP7 and AtGRP8 Oscillations in Arabidopsis thaliana
Figure 2
Systems dynamics for the “optimal” parameter set under 12h∶12h LD and LL conditions.
Solid lines denote solutions of equations (1)–(6) for the “optimal” parameter set from Table 1: A) AtGRP7 pre-mRNA (), mRNA (
), and protein (
) concentrations. B) AtGRP8 pre-mRNA (
), mRNA (
), and protein (
) concentrations. Dashed lines denote the protein concentration
of the core oscillator gene LHY/CCA1. Shown are the last two days in 12h∶12h LD conditions (
) and the first four days after switching to constant light conditions (
). Throughout this paper, a gray-shaded background indicates darkness.
