Function of chromatin regulators in seed development. a Prior to fertilization, DNA hypomethylation by DME enables maternal expression of PRC2, which deposits H3K27me3 at auxin response genes to inhibit the development of non-embryonic tissues. PRC2 acts in concert with LHP1 and histone H2A deubiquitinases (UBPs). b Post fertilization, paternally expressed genes raise the auxin hormone level and activate non-embryonic tissue development; this requires the endosperm expressed TF AGL62. The increased auxin levels reduce PRC2 expression. c CHD and SWI/SNF chromatin remodelers contribute to embryo pattering after fertilization. Black, chromatin regulators; blue, transcription factors; green, hormones
