Reciprocity Between Robustness of Period and Plasticity of Phase in Biological Clocks

Abstract: Circadian clocks exhibit the robustness of period and plasticity of phase against environmental changes such as temperature and nutrient conditions. Thus far, however, it is unclear how both are simultaneously achieved. By investigating distinct models of circadian clocks, we demonstrate reciprocity between robustness and plasticity: higher robustness in the period implies higher plasticity in the phase, where changes in period and in phase follow a linear relationship with a negative coefficient. The robustne… Show more

“…In conclusion, GLVs and sesquiterpene HIPVs emitted from N. attenuata leaves provide two ways of conveying timely information to native predators: sesquiterpenes are persistent and temporally synchronized with predator activity, whereas GLVs are transient but convey relevant temporal information as a result of qualitative blend differences (Figure ). Robustness is a ubiquitous characteristic of biological systems which allows organisms to survive under unpredictable environments (Kitano, ); phenotypic plasticity is one important “fail‐safe” mechanism through which biological systems obtain robustness (Hatakeyama & Kaneko, ; Whitacre, ). We conclude that temporal plasticity in HIPV emissions maintains robustness of plant indirect defence in response to temporally heterogeneous herbivore communities.…”

“…This is a clear signature of another mechanism of period robustness: at higher phosphorylation rates, corresponding to higher α ATP , the rate at which a system goes through state space increases, yet the length of one cycle also increases (4,8). It is important to note that the phenomenon of the variation of the phosphorylation cycle with the bulk ATP level emerges as a prediction of the Paijmans model; we did not deliberately design the model to have this property.…”

“…Compatibility between robustness and plasticity (or sensitivity) to external changes is a basic characteristic of a biological system. In biological clocks, it is represented as reciprocity between robustness of period and plasticity in phase of oscillation [24], and it will be important to uncover a principle of how signaling pathways achieve both sensitivity to certain inputs while keeping robustness to other external changes.…”
