Abstract:
Many plant species can propagate asexually or be regenerated in vitro; but asexual offspring are more likely to maintain environmentally induced epigenetic marks, for instance, inheritance of the prolonged cold-induced 'vernalized state' in overwintering plants through asexual reproduction. Here we demonstrate that 'vernalized state' is reprogrammed during Arabidopsis asexual propagation through somatic embryogenesis. This overturns a long-standing idea, that the vernalized state could not be reset through asexual reproduction, and provides a strategy to erase parental effects on offspring during asexual reproduction.

Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
