表观遗传与花期调控研究进展

Research Progress on Epigenetic and Flowering-time Regulation

目前,关于高等植物成花机理的研究已经取得突破性进展,对表观遗传的研究也越来越深入,而将两者联系起来调控花期的研究虽然还处于初步探索阶段,但已取得了一定的理论成果。本文总结了常见的表观遗传(DNA甲基化、组蛋白修饰、非编码RNA、染色质重塑)在不同开花诱导途径中调控花期的研究进展,为通过表观遗传途径调控花期技术研究提供参考。

At present, it has made breakthrough progress about the research of higher plant flowering mechanism. Along with epigenetics research more and more thoroughly, it has made some theoretical achievements although the study of the linkage between flowering control and epigenetic is still in the preliminary exploration stage. The author summarized present situation about the role of common epigenetics （DNA methylation, histone modification, non-coding RNA, chromatin remodeling） in different flower induction pathway. The purpose of this paper is to provide reference for the study which through the epigenetic technology to regulate flowering-time.
