Abstract:
Understanding the mechanisms that trigger the embryogenic program in plant somatic cells remains a major focus of modern molecular biology, because this process is widely used for clonal propagation, cryopreservation, and genetic transformation. Recently, Iwase et al. demonstrated that the transcription factor WOUND INDUCED DEDIFFERENTIATION 1 (WIND1) can simultaneously promote histone H3 acetylation at lysine 27 and induce expression of genes associated with the embryogenic response, while also activating deacetylation of this histone and repressing genes associated with differentiation.

Chromatin Modification in iPS Cells
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...
