Synchronization of plant circadian oscillators with a phase delay effect of the vein network

Phys Rev Lett. 2007 Aug 31;99(9):098102. doi: 10.1103/PhysRevLett.99.098102. Epub 2007 Aug 29.


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.
