Plant epigenetics has recently gained unprecedented interest, not only as a subject of basic
research but also as a possible new source of beneficial traits for plant breeding. We …

Heritable patterns of gene activity and gene silencing arise by the formation and the propagation
of specific chromatin states that restrict or permit gene expression. In mammals and in …

Transgenerational epigenetic inheritance (TEI), which is the inheritance of expression states
and thus traits that are not determined by the DNA sequence, is often postulated but the …

Evidence for direct, gene‐mediated stable genetic transformation of plant cells of Nicotiana
tabacum is presented. A selectable hybrid gene comprising the protein coding region of the …

Eukaryotic genomes consist to a significant extent of retrotransposons that are suppressed
by host epigenetic mechanisms, preventing their uncontrolled propagation 1 , 2 . However, it …

Maintenance of CG methylation ( m CG) patterns is essential for chromatin-mediated epigenetic
regulation of transcription in plants and mammals. However, functional links between m …

In mammals, the DNA methyltransferase 1 (Dnmt1) faithfully copies the pattern of cytosine
methylation at CpG sites to the newly synthesized strand, and this is essential for epigenetic …

Although the generation of transgenic plants is now routine, the integration of foreign genetic
information has so far been at random sites in the genome. We now present evidence for …
