Phase and amplitude sensitivities of the entrained system. A. Phase and relative amplitude changes resulting from perturbations of the entrained clock in its maximally flexible direction. Solid and open symbols denote WT and 1% wc-1 loop coupling respectively. Perturbed solutions were computed for proportional parameter increases of 2%. Note that the reduction in wc-1 loop coupling strength causes the variation in FRQ protein phase to decrease significantly. B. Comparisons of the FRQ phase changes s_FRQ for WT and 1% loop coupling with the corresponding changes Δϕ_FRQ in FRQ-dependent conidiation phase. s_FRQ and Δϕ_FRQ are similar, indicating that the reduced FRQ phase sensitivity also results in reduced conidiation phase sensitivity.
