摘 要:

昼夜节律属于具有周期性的生物节律, 受到包括非生物胁迫在内许多外界环境的影响。植物昼夜节律与外界环境越相适应, 对非生物胁迫的耐受力越高。本文综述了植物昼夜节律的特点, 生物钟结构及调控, 植物昼夜节律对干旱、盐、寒冷三种非生物胁迫的响应, 并对未来植物昼夜节律与非生物胁迫相互关系的研究前景进行了展望。

Abstract:

Circadian rhythms are the subset of biological rhythms with period, affected by numerous stimuli of exogenous environment, especially abiotic stresses. The more suitable adaptation between plant circadian rhythms and environment, the more capable of resistance to abiotic stresses. In this review, the research advances on the characteristics of plant circadian rhythm, the feedback loops of circadian clock, the response of plant circadian rhythm to drought, salt and cold stresses were presented, meanwhile, the prospective of the future research direction for the plant circadian rhythm and its response to abiotic stresses were addressed.

Key words: circadian rhythm; abiotic stresses; Arabidopsis thaliana; circadian clock
