摘 要:

植物中普遍存在生物钟系统, 使其能够感受外界环境中光强、温度等具有周期性的环境信号, 并通过联锁反馈通路调节下游信号转导网络进而参与调控植物的营养生长、生殖生长、应对非生物胁迫、代谢活动等生长代谢过程, 增强植物的环境适应性。本文综述了近年来生物钟调控植物生长代谢过程的相关研究进展, 以期为今后有关生物钟组分在植物遗传改良上的研究提供理论参考。

Abstract:

The circadian clock system is widespread in plants, which enables it to sense periodic environmental signals such as light intensity and temperature from the external environment. The circadian clock system can regulate downstream signal transduction networks through interlocking feedback loops to participate in the regulation of plant growth and metabolism processes such as vegetative growth, reproductive growth, respond to abiotic stress and metabolic activities, and therefore the environmental suitability of plants will be enhanced. This article summarizes the research progress of the circadian clock regulating plant growth and metabolism in recent years, hoping to provide a theoretical reference for future research on the circadian clock components in plant genetic improvement.

Key words: circadian clock; abiotic-stress; vegetative growth; reproductive growth; plant metabolism
