Transcription in eukaryotes is regulated by many enzymes that influence the nuclear organization of DNA in chromatin. Several of these enzymes regulate histone modifications. These modifications function as a platform for assembly of protein complexes that influence chromatin structure. Dynamic changes between chromatin states that facilitate or inhibit transcription are important in the transcriptional regulation of pathways controlling floral induction in response to environmental and developmental signals. This review focuses on the mechanistic aspects of histone modifications and chromatin changes at flowering-time genes and how these relate to the initiation of flowering.
真核生物中的转录受多种酶的调控，这些酶会影响染色质中DNA的核组织。其中几种酶调控组蛋白修饰。这些修饰作为影响染色质结构的蛋白质复合物组装的平台。染色质状态之间促进或抑制转录的动态变化在响应环境和发育信号控制开花诱导的途径的转录调控中很重要。本综述重点关注开花时间基因处组蛋白修饰和染色质变化的机制方面，以及它们与开花起始的关系。
