摘　　要：某些植物的叶片存在夜间折叠下垂的感夜运动现象,植物感夜运动是由于叶枕运动细胞体积的可逆变化引起的光敏感性膨压运动。这一运动过程的实现不仅需要膜蛋白(泵、载体、离子和水通道)对水和离子通量的严格控制,还受到光信号和生物钟的调控。梳理分析了近年来感夜运动在解剖学、化学生物学,以及光信号和质膜转运蛋白等方面的相关研究,归纳总结了运动细胞体积变化的各种因素,为更好地理解感夜运动提供理论依据。The leaves of some plants have nyctinasty phenomenon of folding and drooping at night.Plant nyctinasty is a light-sensitive turgor movement caused by the reversible change of the volume of pulvinus motor cells.The realization of this movement process not only requires the membrane proteins(pumps,carriers,ions and water channels)to strictly control water and ion flux,but also is regulated by light signals and biological clocks.This paper combs recent studies on plant nyctinasty in anatomy,chemical biology,light signals and plasma membrane transporters and summarizes the various factors of the changes in the volume of motor cells,so as to provide a theoretical basis for a better understanding of plant nyctinasty.
