A mathematical model for a plant circadian oscillator
 
 
Description:  Circadian rhythms are generated at the cellular level by a small but tightly regulated genetic network. They are observed in most organisms on earth and are known to play a major role in successful adaptation to the 24-h cycling environment. Understanding the molecular basis of cellular oscillations is more than an exercise in experimental genetics or biochemistry. Oscillators have characteristics (periodicity, robustness, entrainment) that transcend the properties of individual molecules or those interacting with each other through chemical reactions. These properties can only be fully understood by viewing experimental data from the perspective of quantitative mathematical modelling of chemical oscillatory processes. In the present talk we obtain a mathematical model to simulate the core loop of a plant - the Arabidopsis thaliana - circadian clock. Starting from the simple positive-negative feedback model, we aim to build a more comprehensive model that encompasses the key features of system.
