title: Passing the message on: inheritance of epigenetic traits.
abstract: Epigenetic modifiers play an important role in genome organization, stability and the control of gene expression. Three research groups that are exploring the transfer of epigenetic information between generations have recently published papers. Mary Alleman et al. have shown that RNA-directed chromatin changes mediate paramutation in maize, and Minoo Rassoulzadegan et al. have demonstrated that RNA also plays a role in paramutation in mice. A new aspect of epigenetic regulation has been revealed by Jean Molinier et al. - they have demonstrated that the memory of exposure to stress is transferred through several generations.
