Abstract

Precise timing of flowering in plants is critical for their growth and reproductive processes. One factor controlling flowering time is the cycle of light and darkness within a day, known as the photoperiod. Plants are classified into long-day, short-day, and day-neutral plants based on light requirements for floral initiation. Although the molecular mechanisms that govern this differentiation remain incompletely understood, studies have consistently shown that the circadian clock plays a central role in regulating photoperiod response across diverse plant species. However, there is a scarcity of reviews describing the regulatory network linking the circadian clock with photoperiodic flowering. This review summarizes that regulatory network, focusing on the distinct roles of clock genes in long-day and short-day plants. We also discuss the strategies of clock gene mutations contributing to geographic variation in long-day and short-day crops.
生物钟对开花时间的调节:从拟南芥到农作物
精确的开花时间对植物的生长和繁殖过程至关重要。控制开花时间的一个因素是一天内的光暗循环,称为光周期。植物根据成花所需的光照可分为长日照植物、短日照植物和中性日照植物。尽管控制这种分化的分子机制仍不完全清楚,但研究一致表明,昼夜节律钟在调节不同植物物种的光周期反应中起着核心作用。然而,描述生物钟和光周期开花之间联系的调控网络的综述很少。本文综述了生物钟调控网络,重点介绍了生物钟基因在长日照植物和短日照植物中的不同作用。我们还讨论了时钟基因突变对长日照和短日照作物地理变异的影响。
