Histone modifiers control chromatin architecture by triggering formation of chromatin repressive or active domains to allow gene coregulation. Model of the formation of tissue-specific active and repressive chromatin domains in Arabidopsis seedlings. The green structures represent active compartments, which are associated with H3K9ac-marked euchromatin. The pink structures represent PcG-repressive compartments, which are associated with H3K27me3-marked facultative heterochromatin.
