Selected aspects of transgenerational epigenetic inheritance and resetting in plants


Paszkowski, J; Grossniklaus, U (2011). Selected aspects of transgenerational epigenetic inheritance and resetting in plants. Current Opinion in Plant Biology, 14(2):195-203.

Abstract

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 molecular mechanisms involved are only rarely verified. This especially applies to the heritability of environmentally induced traits, which have gained interest over the last years. Here we will discuss selected examples of epigenetic inheritance in plants and artificially divide them according to the occurrence of inter-generational resetting. The decision which epigenetic marks are reset and which ones are not is crucial for the understanding of TEI. We will consider examples of epialleles found in natural populations and epialleles induced by genetic and/or environmental factors used in experimental setups.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
