转录因子可以启动靶基因在特定组织中的表达，从而控制一些发育过程，然而,高度有序的染色质结构的确立和动态调控更是植物发育的重要组成部分。核小体装配和沉积复合体，例如CAF1和HIRA1，它们通过确立核小体的位置或用组蛋白变体取代典型的组蛋白在决定染色体结构的早期进程中就起到重要的作用。组蛋白变体和组蛋白翻译后修饰也参与调控很多重要的植物发育基因的表达。这些机制在植物以及其它真核生物中都是高度保守的。染色质结构的严谨控制是极为重要的，因为生物体要维持去分化的细胞状态才能保证胚后发育的进行。因此，对植物染色质结构和构造及其相关途径进行合理的分析和深入的研究是至关重要的。

Although some of the developmental control is carried out by specific transcription factors, that triggers the expression of individual genes in specific tissues, establishment and dynamic regulation of a higher order chromatin structure is an essential component of plant development. Nucleosome assembly and depositing complexes such as CAF1, or HIRA1 are among the very early steps in determining chromatin architecture by establishing nucleosome positioning or substituting canonical histones with histone variants. Histone variants and post-translational modification of histone tails also regulate the expression of many key developmental genes in plants. These mechanisms are highly conserved across the eukaryotic kingdoms although in plants, owing to the maintenance of de-differentiated cell states that allow for post-embryonic changes in development, strict control of chromatin architecture is even more paramount. Therefore, a proper analysis and in-depth knowledge of the pathways that accomplish general chromatin structure and architecture is of crucial importance.
