| Outline of Final Research Achievements |
The circadian clock system is basically cell-autonomous in plants. On the other hand, circadian clock phase of individual cells are presumably influenced by other cells.
In order to understand the mechanisms of intercellular clock phase communication among cellular circadian clocks in plants, we have utilized a single-cell bioluminescence monitoring system in higher plants. In this project we newly developed a manipulation system of illumination on a microarea in duckweed plants for long-term experiments of circadian rhythms. We combined this device with the bioluminescence reporter imaging technology. During this project we also established a stable transformation methods in a duckweed lemna minor and lemna turionifera. This tecunique also enable us to analyse circadian phase synchronization mechanisms between tissues and/or individual organs.
