Recent work has shown that changing the photoperiod induces stress in Arabidopsis thaliana. It has particularly dramatic consequences in cytokinin-deficient plants and clock mutants. Here, we argue that studying the impact of an altered photoperiod will provide novel insights into the circadian clock, factors regulating it, and pathways under its control.

通过改变光周期对植物产生新的胁迫

最近的工作表明，改变光周期会在拟南芥中引起胁迫。它对缺乏细胞分裂素的植物和时钟突变体具有特别显着的影响。在这里，我们认为研究改变光周期的影响将提供对生物钟，其调节因素以及受其控制的途径的新颖见解。
