摘要:

表观遗传是DNA序列不变而基因表达发生可遗传改变的生物现象,包括DNA甲基化、组蛋白修饰及变体、RNA修饰、染色质重塑和非编码RNA等。表观遗传主要在转录和转录后水平调控基因表达及转座子活性,在作物重要农艺性状形成和倍性育种等方面发挥重要调控作用。综述了目前与作物育种直接相关表观遗传调控研究的重要进展,并分析了其应用于作物育种上的潜力及途径方法,以期加快和推动植物表观遗传调控的基础与应用研究。

Abstract:

Epigenetic is a biological phenomenon that DNA sequence unchanged but gene expression was genetically altered, and it includs DNA methylation, histone modification and variants, RNA modification, chromatin remodeling and non coding RNA etc. Epigenetic mainly regulates gene expression and transposon activity at transcriptional and post transcriptional levels. More and more research showed that epigenetic plays an important role in the formation of important agronomic traits and ploidy breeding of crops. This paper reviewed the important progress in the research of epigenetic regulation directly related to crop breeding, and analyzed its potential and ways of application in crop breeding, which were expected to accelerate and promote the basic and applied research of plant epigenetic regulation.

Key words: epigenetic, crop breeding, epigenetic variation
