Involvement of Multiple Gene-Silencing Pathways in a Paramutation-like Phenomenon in Arabidopsis.

Abstract excerpt

Paramutation is an epigenetic phenomenon that has been observed in a number of multicellular organisms. The epigenetically silenced state of paramutated alleles is not only meiotically stable but also "infectious" to active homologous alleles. The molecular mechanism of paramutation remains unclear, but components involved in RNA-directed DNA methylation (RdDM) are required. Here, we report a multi-copy...
