Epigenetic information storage in plants

Arbeitsgruppe Transcription Control in Flowering Time



An epigenetic memory determines how strongly genes are expressed. Polycomb Group protein complexes stably shut down genes by compacting the packaging material of DNA. Recent studies in plants showed that two different and short DNA sequences, called teloboxes and RY motifs, are involved in this epigenetic process. Genes that are under epigenetic regulation are enriched in both motifs, often in combination. Specialized transcription factors, which recognize teloboxes and RY motifs, also directly bind to building blocks of the Polycomb Group and thus stabilize the memory of target genes.
