Plant epigenetics has become one of the hottest topics of research not only as a subject of basic research but also as a possible new source of beneficial traits for plant breeding. In addition, epigenetic mechanisms are also crucial to appropriate plant reactions to stress. Given the sessile lifestyle and the late differentiation of the germ line, plants can perceive stresses during vegetative growth and also memorize them, possibly by epigenetic mechanisms. Plants use three systems to initiate and regulate epigenetic gene regulation, like other higher organisms, which include DNA methylation, histone modifications, and RNA interference. New concepts are being evolved to show how these epigenetic components interact and stabilize each other. The role of epigenetic mechanisms in hybrid vigor and epigenetic transgene silencing is also being explored. In this chapter, we have tried to highlight the epigenetic mechanisms that play key roles in plants. ? Springer India 2015.
