Silencing of rRNA by epigenetic modification in newly formed amphidiploid plants. rRNA genes active in genomes of species I (A) and II (B). After formed amphidiploid plants, rRNA derived from species I is silenced by increased DNA methylation and enrichment of histone modification (H3K27me3 and H3K9me2) (C).
