In eukaryotic cells, chromatin, a highly dynamic nucleoprotein complex, plays a critical role in
controlling gene expression notably by regulating the interaction between transcription factors and
regulatory elements. The structure of the chromatin is determined by epigenetic mechanisms,
including DNA methylation, histone modifications, and chromatin remodeling. A growing body of
evidence indicates that epigenetic regulations are involved in plant adaptation to environmental
stresses, and in plant development, including flowering control, fruit and root development, as well
as seed maturation and germination. Furthermore, epigenetic mechanisms have the potential to
stabilize cell identity and maintain tissue organization. Hence, epigenetic diversity is now emerging
as a new source of phenotypic variation to improve adaptation to changing environment and ensure
yield and quality of crops. The 14 articles published in this Research Topic highlight recent
progresses, opinions, and reviews to advance our knowledge in the role of the epigenome on
controlling plant development, plant response to environmental stresses, and plant evolution. For
instance, gene duplication and chromatin remodeling contribute to increase the morphological and
cellular complexity of plants during their evolution according to Hajheidari et al.
