Epigenetic modifications are stable but potentially reversible alterations in gene expression that occur without permanent changes in DNA sequence. They can be transmitted mitotically to daughter cells and, in some cases, even to the next generation. Epigenetic modifications have an essential role in determining cell fate and regulating flowering. They also defend plants against virus infection, help maintain genome integrity, and prevent deleterious expression of transposable elements and retroviruses.
Recent years have seen a dramatic increase of research activity in this area. This is the first volume to provide an overview of our current knowledge of epigenetic mechanisms in plants. It is directed at researchers and professionals working in plant molecular genetics, developmental biology and biochemistry, and will provide a point of entry to the detailed literature.

Given the rapid increase in publication of scientific papers involved in plant epigenetics, a book that provides comprehensive coverage of recent knowledge is earnestly desired by Plant Scientists. Plant Epigenetics edited by Peter Meyer is published just at the right moment.Annals of Botany, 1-1, 2007
