The plant circadian clock has a pervasive influence on many aspects of plant biology and is proposed to function as a developmental manager. To do so, the circadian oscillator needs to be able to integrate a multiplicity of environmental signals and coordinate an extensive and diverse repertoire of endogenous rhythms accordingly. Recent studies on tissue-specific characteristics and spatial structure of the plant circadian clock suggest that such plasticity may be achieved through the function of distinct oscillators, which sense the environment locally and are then coordinated across the plant through both intercellular coupling and long-distance communication. This review summarizes the current knowledge on tissue-specific features of the clock in plants and their spatial organization and synchronization at the organismal level.
植物生物钟对植物生物学的许多方面都有广泛的影响，被认为是一种发育管理器。为此，生物钟振荡器需要能够整合多种环境信号，并相应地协调广泛多样的内源性节律。最近关于植物生物钟的组织特异性特征和空间结构的研究表明，这种可塑性可能是通过感知局部环境的不同振荡器的功能来实现的，然后通过细胞间耦合和长距离通讯在整个植物中进行协调。本文综述了目前关于植物生物钟的组织特异性特征及其在生物体水平上的空间组织和同步的知识。
