摘要

昼夜节律是一种约24小时的生物振荡,使生物体能够预测每日的环境周期,以便它们可以指定与这些变化相一致的适当的昼夜功能。动物和真菌的分子时钟由转录-翻译反馈回路组成,植物时钟由多个互锁的反馈回路组成,蓝藻时钟由涉及三种主要蛋白质的磷酸化循环驱动。尽管这些系统的核心时钟机制不同,但所有的生物钟都能够缓冲周期长度,以应对周围生长环境的变化,如温度和营养物质。这种被称为补偿的定义能力对于适当的计时是至关重要的,但是其潜在的机制仍然是难以捉摸的。在这里,我们研究了五种昼夜节律系统中已知的参与者和当前的补偿模型。虽然这些系统的补偿模型尚未统一,但它们之间存在共同的主题,包括通过翻译后修饰的温度依赖变化进行调节。

A Compensated Clock: Temperature and Nutritional Compensation Mechanisms Across Circadian Systems

A Compensated Clock: Temperature and Nutritional Compensation Mechanisms Across Circadian Systems

Circadian rhythms are ∼24-h biological oscillations that enable organisms to anticipate daily environmental cycles, so that they may designate appropriate day/night functions that align with these changes. The molecular clock in animals and fungi consists of a transcription-translation feedback loop, the plant clock is comprised of multiple interlocking feedback-loops, and the cyanobacterial clock is driven by a phosphorylation cycle involving three main proteins. Despite the divergent core clock mechanisms across these systems, all circadian clocks are able to buffer period length against changes in the ambient growth environment, such as temperature and nutrients. This defining capability, termed compensation, is critical to proper timekeeping, yet the underlying mechanism(s) remain elusive. Here we examine the known players in, and the current models for, compensation across five circadian systems. While compensation models across these systems are not yet unified, common themes exist across them, including regulation via temperature-dependent changes in post-translational modifications.

期刊介绍: molecular – cellular – biomedical – physiology – translational research – systems - hypotheses encouraged BioEssays is a peer-reviewed, review-and-discussion journal. Our aims are to publish novel insights, forward-looking reviews and commentaries in contemporary biology with a molecular, genetic, cellular, or physiological dimension, and serve as a discussion forum for new ideas in these areas. An additional goal is to encourage transdisciplinarity and integrative biology in the context of organismal studies, systems approaches, through to ecosystems, where appropriate.
