From http://www.nature.com/nature/journal/v447/n7143/full/447395a.html:
"Epigenetics is typically defined as the study of heritable changes in gene expression that are not due to changes in DNA sequence. Diverse biological properties can be affected by epigenetic mechanisms: for example, the morphology of flowers and eye colour in fruitflies.
............
In this Insight, we take a wide view of the epigenetics field, highlighting current topics of interest — from the influence of chromatin and chromosome organization on gene expression to the roles of epigenetic mechanisms in development and disease. And under this broad umbrella, the very definition of epigenetics is scrutinized. We hope that you enjoy these exciting reviews and thank the authors for their contributions."
