Inherited variation at the epigenetic level: paramutation from the plant to the mouse.

Abstract excerpt

In contrast with a wide definition of the 'epigenetic variation', including all changes in gene expression that do not result from the alteration of the gene structure, a more restricted class had been defined, initially in plants, under the name 'paramutation'. It corresponds to epigenetic modifications distinct from the regulatory interactions of the cell differentiation pathways, mitotically stable and...
