Circadian rhythms in transcription ultimately result in oscillations of key biological processes. Understanding how transcriptional rhythms are generated in plants provides an opportunity for fine-tuning growth, development, and responses to the environment. Here, we present a succinct description of the plant circadian clock, briefly reviewing a number of recent studies but mostly emphasizing the components and mechanisms connecting chromatin remodeling with transcriptional regulation by the clock. The possibility that intergenomic interactions govern hybrid vigor through epigenetic changes at clock loci and the function of epialleles controlling clock output traits during crop domestication are also discussed.

基因转录的昼夜节律最终会影响到关键生物学进程的波动。理解植物中的昼夜节律是如何产生的将有利于精细调控植物的生长、发育以及对环境的响应。本文，作者简明扼要地描述了植物的生物钟，简要地回顾了最近这方面的研究，主要侧重于植物中生物钟介导的染色质重塑和转录调控的机制。作者还讨论了染色体间的互作通过改变生物钟位点的表观修饰产生杂种优势，以及作物驯化过程中控制生物钟输出性状的表观等位基因的功能。
