Abstract
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 require, and are the result of, extensive transcriptional reprogramming which importantly are mediated by essential epigenetic mechanisms such as DNA methylation, different histone variants and modifications, as well as by non-coding regulatory RNAs. Studying these mechanisms therefore is essential for understanding the regulation of gene expression during germination. In this review we summarize our current knowledge of these mechanisms in the context of Arabidopsis thaliana seed biology 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.
