Plant Epigenomics

Guest Editors: Nathan Springer and Claudia Köhler

Epigenetic modifications (表观修饰) contribute to phenotypic variation at multiple levels, from gene regulation, to development, stress response, and population-level phenotypic diversity and evolution. As sessile organisms (固着生物), plants are particularly dependent on epigenetic mechanisms to express diverse phenotypic responses from the same genome sequence. Technological advances that allow genome-wide analysis of DNA or histone modifications (组蛋白修饰) coupled with new opportunities for editing the epigenome (表观基因组) have the potential to reveal the functions of epigenetic regulation in plants. Here, Genome Biology highlights advances in our understanding of the functions of epigenetic modifications, and the application of this knowledge.

Genome Biology专刊：表观修饰从多个水平贡献于表型变异，包括基因调控、发育、胁迫响应以及群体层面的表型多样性和进化。作为固着生物，植物尤其依赖于表观机制从同样的基因组序列表达不同的表型响应。近年来技术上的提升使得基因组范围的DNA或组蛋白修饰分析偶联表观基因组编辑成为可能，能够帮助揭示植物表观调控的功能。Genome Biology本次"植物表观基因组学"专刊重点突出了表观修饰功能的理解及应用。
