摘要:

光照是影响植物生长发育的重要环境因子, 开花是高等植物生活史上最重要的事件。植物通过光受体感知外界环境中的光照变化, 激活一系列信号转导过程从而适时开花。该文介绍了高等植物光受体的种类、结构特征和生理功能的研究进展, 并系统阐述了红光/远红光受体光敏色素、蓝光受体隐花色素以及FKF1/ZTL/LKP2等介导光信号调控植物开花的分子机制, 包括光受体对CO转录及转录后水平调控和对FT转录水平的调控等。此外, 还介绍了光受体整合光信号与温度和赤霉素等信号调控植物开花的研究进展, 并展望了未来的研究方向。

Abstract:

Light is an important environmental factor that affects plant growth and development. Flowering is the most important event in higher plants. Plants perceive accurately changes in the surrounding light environments by photoreceptors, thus activating a series of signaling transduction processes and initiating flowering. Here, we summarized the current understanding of the structural characteristics and physiological functions of various photoreceptors in higher plants. We reviewed the molecular mechanisms of phytochromes, cryptochromes, and FKF1/ZTL/LKP2 in mediating signaling transduction and flowering time, including transcriptional and post-transcriptional regulation of CO and FT. Finally, we described the advances in photoreceptor-mediated-integration of light, temperature, and gibberellin signals in regulating flowering. Future directions in this area were also proposed.
