The clockwork of plant circadian oscillators has been resolved through investigations in Arabidopsis thaliana. The circadian oscillator is an important regulator of much of plant physiology, though many of the mechanisms are unclear. New findings demonstrate that the oscillator adjusts phase and period in response to abiotic and biotic signals, providing insight in to how the plant circadian oscillator integrates with the biology of the cell and entrains to light, dark and temperature cycles. We propose that the plant circadian oscillator is dynamically plastic, in constant adjustment, rather than being an isolated clock impervious to cellular events.
通过对拟南芥的研究，植物生物钟振荡器的运转机制已经得到了解决。生物钟振荡器是植物生理学的重要调节因子，尽管许多机制尚不清楚。新的发现表明，振荡器会根据非生物和生物信号调整相位和周期，这为我们深入了解植物生物钟振荡器如何与细胞生物学相整合以及如何与光、暗和温度周期同步提供了线索。我们提出，植物生物钟振荡器是动态可塑的，处于不断的调整之中，而不是一个与细胞事件隔绝的独立时钟。
