Epigenetic reprogramming that prevents transgenerational inheritance of the vernalized state.

ABSTRACT: The reprogramming of epigenetic states in gametes and embryos is essential for correct development in plants and mammals. In plants, the germ line arises from somatic tissues of the flower, necessitating the erasure of chromatin modifications that have accumulated at specific loci during development or in response to external stimuli. If this process occurs inefficiently, it can lead to epigenetic states being inherited from one generation to the next. However, in most cases, accumulated epigenetic modifications are efficiently erased before the next generation. An important example of epigenetic reprogramming in plants is the resetting of the expression of the floral repressor locus FLC in Arabidopsis thaliana. FLC is epigenetically silenced by prolonged cold in a process called vernaliza
