摘要

种子萌发作为一个发育过程已被广泛研究，以模式植物拟南芥为研究对象。从种子的成熟和休眠调控到萌发和萌发后的转变，其种子生物学已被普遍了解。这些事件需要并且是广泛的转录重编程的结果，重要的是，转录重编程是由基本的表观遗传机制介导的，如DNA甲基化，不同的组蛋白变异和修饰，以及非编码调节rna。因此，研究这些机制对于理解萌发过程中基因表达的调控至关重要。本文综述了拟南芥种子生物学背景下这些机制的研究进展，并对需要进一步研究的方面进行了讨论。

Non-coding and epigenetic mechanisms in the regulation of seed germination in Arabidopsis thaliana.

Seed germination as a developmental process has been extensively studied using the model plant Arabidopsis thaliana. Its seed biology is generally well understood, from the regulation of seed maturation and dormancy to germination and the post-germinative transition. These events are the result of extensive transcriptional reprogramming mediated by essential epigenetic mechanisms such as DNA methylation, different histone variants and modifications, and non-coding regulatory RNAs. Studying these mechanisms is essential for understanding the regulation of gene expression during germination. In this review, we summarize our current knowledge of the mechanisms regulating seed biology in Arabidopsis and discuss aspects requiring further study.

期刊介绍： The Journal of Experimental Botany publishes high-quality primary research and review papers in the plant sciences. These papers cover a range of disciplines from molecular and cellular physiology and biochemistry through whole plant physiology to community physiology. Full-length primary papers should contribute to our understanding of how plants develop and function, and should provide new insights into biological processes. The journal will not publish purely descriptive papers or papers that report a well-known process in a species in which the process has not been identified previously. Articles should be concise and generally limited to 10 printed pages.
