High production of a transgenic lettuce through an application of circadian resonance

当植物的生物钟与环境周期一致时，其生长速率和光合速率都取较高值。这一现象被称为昼夜节律共振，莴苣可以观察到这种现象，这可能对莴苣的植物工厂有帮助，推测这一现象是由时钟基因的基因表达共振引起的，通过对其机理的阐明，有望发展到分子水平的控制。因此，本研究主要研究了以下几个方面的问题：（1）利用光脉冲调控生物钟与环境周期的同步;（2）生物钟调控对植物生长、形态和荧光素酶蛋白产生的影响。

When the circadian clock of the plant synchronizes to the environmental cycles, the growth and photosynthesis rates take a higher value. This phenomenon is called circadian resonance and it may be useful in the plant factory for lettuce because lettuce can observe it. It is supposed that this phenomenon is caused by the resonance in the gene expression of clock genes and can expect the development to the control of the molecular level by elucidation of the mechanism. Therefore, in this research, following subjects were addressed :(1) a control of synchronization between circadian clock and environmental cycle using light pulse,(2) effect of that clock control to the growth, morphology and the production of luciferase protein in plant.
