Role of chromatin remodelers in callus formation and root development. a Spontaneous de-differentiation of meristematic plant tissues is prevented by Polycomb repression (PRC2, PRC1), while the CHD chromatin remodeler PKL prevents induced callus formation. Histone deacetylation (HDA9) promotes de-differentiation in induced callus. b Stem cell maintenance is promoted by upregulation of auxin transport (via PIN1) through BRM/SWP73B and histone acetylation (GCN5) to promote expression of the PLT TFs. It also requires repression of CDF4 by WOX5 and TPL/HDA19. Differentiation is promoted by PRC2 (which represses PIN1 expression) and by ROW1, which prevents expansion of WOX5 expression. Black, chromatin regulators; blue, transcription factors; green, hormones
