A Circadian Clock-Regulated Toggle Switch Explains AtGRP7 and AtGRP8 Oscillations in Arabidopsis thaliana
Figure 7
Damped, autonomous, and noise-induced oscillations after decoupling the slave from the core oscillator.
A) Relaxation dynamics are observed for the optimal parameter set from Table 1. Dashed lines denote the corresponding fixed points. B) After changing the AtGRP7 and AtGRP8 protein degradation rates to and
, respectively, the slave oscillator develops autonomous oscillations. C) Pure noise-induced oscillations of a single cell (
) for the parameter set from Table 1. D) Same after averaging over an ensemble of
cells. See Text S1 C/D for further details (especially the noise-strength
).
