Abstract

There is considerable excitement about the potential for epigenetic information to contribute to heritable variation in many species. Our understanding of the molecular mechanisms of epigenetic inheritance is rapidly growing, and it is now possible to profile the epigenome at high resolution. Epigenetic information plays a role in developmental gene regulation, response to the environment, and in natural variation of gene expression levels. Because of these central roles, there is the potential for epigenetics to play a role in crop improvement strategies including the selection for favorable epigenetic states, creation of novel epialleles, and regulation of transgene expression. In this review we consider the potential, and the limitations, of epigenetic variation in crop improvement.
