Plants monitor changes in photoperiod and temperature to synchronize their flowering with seasonal changes to maximize fitness. In the Arabidopsis photoperiodic flowering pathway, the circadian clock-regulated components, such as FLAVIN-BINDING, KELCH REPEAT, F-BOX 1 and CONSTANS, both of which have light-controlled functions, are crucial to induce the day-length specific expression of the FLOWERING LOCUS T (FT) gene in leaves. Recent advances indicate that FT transcriptional regulation is central for integrating the information derived from other important internal and external factors, such as developmental age, amount of gibberellic acid, and the ambient temperature. In this review, we describe how these factors interactively regulate the expression of FT, the main component of florigen, in leaves.
植物通过监测光周期和温度的变化，使其开花期与季节性变化同步，以最大限度地提高适应性。在拟南芥的光周期开花途径中，生物钟调节的成分，如黄素结合蛋白、KELCH 重复、F-BOX1 和 CONSTANS，它们都具有光控功能，对于诱导叶片中 FLOWERING LOCUS T（FT）基因的特定于日长的表达至关重要。最近的进展表明，FT 转录调控对于整合来自其他重要的内部和外部因素的信息至关重要，如发育年龄、赤霉素的量和环境温度。在这篇综述中，我们描述了这些因素如何相互作用调节 FT 的表达，FT 是成花素的主要成分，在叶片中表达。
