蓝光受体ZTLs家族调控植物光周期途径研究进展

Research Advances of in the Regulation of the Blue Light Receptor ZTLs in Plant Photoperiodic Pathway

光周期途径是调控植物开花的重要途径之一,在长期的进化过程中,植物对光周期途径中的光诱导形成了极其精细和完善的光感受系统。植物接收光信号主要通过光感受系统中的光受体(photoreceptor)实现。ZTLs家族是一类蓝光受体蛋白,泛素化调节植物体内蛋白质的降解,在光信号向生物钟输入和调节下游开花基因表达中发挥重要作用。本文对不同植物中ZTLs家族蛋白的结构、功能等研究进行了综述与展望,为阐明ZTLs家族通过光周期途径调控开花的机制提供了一定的理论依据。

Photoperiodic pathway is one of the important ways to regulate the flowering time in plants, during the long evolutionary process, plants have formed an extremely precise and sophisticated light-sensitive system in the photoperiod pathway. Plants receive the light signal which is mainly completed by the photoreceptor of light receptor system. The ZTLs family is a class of blue light receptor proteins which regulate the degradation of proteins in plant, ubiquitination enzymes,which play an important role in the light signal entering the circadian clock and regulating the expression of flowering genes downstream. In this study, reviewed and predicted the research on the structure and function of ZTLs family proteins in different plants, and provides a certain theoretical basis for understanding and studying the mechanism of ZTLs family in regulating flowering through photoperiodic pathway.
