Abstract
Nearly all cells in plants show self-sustained circadian oscillation, which is generated through expression of clock genes and interacts each other via the diffusion of materials. Therefore, the plant can be considered as a coupled oscillator system. In general, the coupled oscillator system can regulate itself and produces various spatiotemporal patterns. Hence this mathematical approach may advance our understanding of the self-regulation mechanism in plant.
In this lecture, I introduce the synchronization and the spatiotemporal patterns in plant circadian clocks using transgenic Arabidopsis thaliana CCA1::LUC with the clock gene CCA1 fused to a modified firefly luciferase gene. I explain the mathematics of the plant circadian clocks as a coupled oscillator system, and then discuss about the self-regulation mechanism in plant.
