Abstract

Synchronization phenomena in coupled circadian oscillators of plant leaves were investigated experimentally using bioluminescence technology for a clock gene. Analyzing the phase of circadian oscillation, the phase-wave propagations and the phase delay caused by the vein network were observed. We describe these phase dynamics using a two-layer model with coupled Stuart-Landau equations. Global synchronization of circadian oscillators in the leaf is also investigated.

摘要

利用生物钟基因的生物发光技术，对植物叶片耦合生物钟振荡器中的同步现象进行了实验研究。通过分析昼夜节律振荡的相位，观察到了由叶脉网络引起的相位波传播和相位延迟。我们使用耦合斯图尔特-朗道方程的两层模型来描述这些相位动力学。还研究了叶片中生物钟振荡器的全局同步。
