植物利用生物钟使它们的生理和发育事件与环境中每日和每年的变化同步。近年来拟南芥研究的进展使我们对生物钟和光周期的分子机制有了更好的了解。其中一个最重要的问题是，在拟南芥中研究的机制是否在其他植物中保守。许多拟南芥时钟基因的同源性已经在多种植物中被发现，一些基因的功能已经被表征。植物的生物钟似乎是相似的。最近分子遗传学的成功也揭示了谷物光周期开花的机制。昼长植物和昼短植物之间的昼长感知机制似乎比昼夜节律时钟的差异更大。
Plants utilize circadian clocks to synchronize their physiological and developmental events with daily and yearly changes in the environment. Recent advances in Arabidopsis research have provided a better understanding of the molecular mechanisms of the circadian clock and photoperiodism. One of the most important questions is whether the mechanisms studied in Arabidopsis are conserved in other plants. Homologs of many Arabidopsis clock genes have been identified in various plants and some gene functions have been characterized. It seems that the circadian clocks in plants are similar. Recent success in molecular genetics has also revealed the mechanisms of photoperiodic flowering in cereals. The day-length sensing mechanisms appear to have diverged more between long-day plants and short-day plants than the circadian clock.
