A REF6-dependent H3K27me3-depleted state facilitates gene activation during germination in Arabidopsis [RNA-Seq]


ABSTRACT: We report transcriptome changes and genome-wide dynamics of H3K27me3 during seed germination in Arabidopdsis, and investigate the impact of REF6-mediated H3K27 demethylation on germination. Compared with transcriptome changes, we discover delayed H3K27me3 reprogramming closely associated with the embryo to vegetative cell fate switch. REF6-mediated H3K27 demethylation promotes germination but does not significantly contribute to H3K27me3 dynamics during germination, but rather stably establishes an H3K27me3-depleted state permissive to transcription. By analyzing REF6 genomic binding, we show that it is absent from mature embryo chromatin and gradually establishes occupancy during the course of germination to counteract increased PRC2 activity.
