Epigenetics in Health and Disease

3. Chromatin dynamics and chromatin remodeling in plants

Chromatin remodeling plays a crucial role throughout plant development, including embryonic and post-embryonic developmental processes such as seed maturation, germination, organogenesis, and flowering. Plant developmental plasticity is regulated by a number of epigenetic regulatory switches operating at the embryo stage as well as during the transition to postembryonic development, in sharp contrast to animals where epigenetic states are established early during embryonic development and cell/tissue differentiation. For this reason, plants might require a higher degree of flexibility in chromatin remodeling. Both shoot and root apical meristems (SAM and RAM) contain groups of pluripotent ...
