摘要: 生物钟几乎参与调控了植物体所有的新陈代谢、生长发育过程,使植物体与外界环境条件达到时间和空间的同步,极大地增强了植物环境适应性和竞争能力。笔者首先从植物生物钟的研究历史入手,回顾了中国古代农业生产中对节律性的认识和应用;然后介绍了现代植物生物钟研究的起源、基本概念和理论知识;最后重点论述了本领域的最新研究进展,揭示了植物生物钟作为复杂的信号转导网络的“整体水平”调控特性和“牵一发而动全身”的独特性。

Abstract: Circadian clock generates endogenous rhythms to confer the fitness advantages for most organisms. Plants with the evolved self-sustaining rhythms could anticipate the changes of environment, synchronize own growth and development with oscillated outer signals. This review summarizes the emerging of research work on the various circadian rhythms, introduces the concepts of chronobiology and related theory, etc, and describes in detail on the current basic network architecture of circadian systems of higher plants, including the prominent transcriptional and posttranslational mechanism.

Key words: biological clock, circadian rhythm, chronobiology, plant
