A wide range of biological processes exhibit circadian rhythm, enabling plants to adapt to the environmental day-night cycle. This rhythm is generated by the so-called 'circadian clock'. Although a number of genetic approaches have identified >25 clock-associated genes involved in the Arabidopsis clock mechanism, the molecular functions of a large part of these genes are not known. Recent comprehensive studies have revealed the molecular functions of several key clock-associated proteins. This progress has provided mechanistic insights into how key clock-associated proteins are integrated, and may help in understanding the essence of the clock's molecular mechanisms.
广泛的生物过程表现出昼夜节律，使植物能够适应环境的日-夜循环。这种节律是由所谓的“生物钟”产生的。虽然有许多遗传方法已经确定了 >25 个与生物钟机制相关的基因，但这些基因的大部分分子功能尚不清楚。最近的综合研究揭示了几个关键生物钟相关蛋白的分子功能。这一进展为关键生物钟相关蛋白如何整合提供了机制上的见解，并可能有助于理解生物钟分子机制的本质。
