Eukaryotic genes are packaged into dynamic but stable chromatin structures to deal with transcriptional reprogramming and inheritance during development. Chromatin remodeling factors and histone chaperones are epigenetic factors that target nucleosomes and/or histones to establish and maintain proper chromatin structures during critical physiological processes such as DNA replication and transcriptional modulation. Root apical meristems are vital for plant root development. Regarding the well-characterized transcription factors involved in stem cell proliferation and differentiation, there is increasing evidence of the functional implications of epigenetic regulation in root apical meristem development. In this review, we focus on the activities of chromatin remodeling factors and histone chaperones in the root apical meristems of the model plant species Arabidopsis and rice.
真核基因被包装成动态但稳定的染色质结构,以应对发育过程中的转录重编程和遗传。染色质重塑因子和组蛋白伴侣是表观遗传因子,它们靶向核小体和/或组蛋白,在 DNA 复制和转录调节等关键生理过程中建立和维持适当的染色质结构。根尖分生组织对植物根的发育至关重要。关于参与干细胞增殖和分化的特征明确的转录因子,越来越多的证据表明表观遗传调控在根尖分生组织发育中的功能意义。在这篇综述中,我们重点介绍了模式植物拟南芥和水稻根尖分生组织中染色质重塑因子和组蛋白伴侣的活性。
