Plants as sessile organisms have remarkable developmental plasticity ensuring heir
continuous adaptation to the environment. An extreme example is somatic embryogenesis …

Histone methylation plays a fundamental role in regulating diverse developmental
processes and is also involved in silencing repetitive sequences in order to maintain …

Trimethylation of histone H3 lysine 27 (H3K27me3) plays critical roles in regulating animal
development, and in several cases, H3K27me3 is also required for the proper expression of …

Polycomb group complexes, which are known to regulate homeotic genes, have now been
found to control hundreds of other genes in mammals and insects. First believed to …

Polycomb-group (PcG) genes encode chromatin proteins involved in stable and heritable
transcriptional silencing. PcG proteins participate in distinct multimeric complexes that …

TERMINAL FLOWER 2/LIKE HETEROCHROMATIN PROTEIN 1 (TFL2/LHP1) is the only
Arabidopsis protein with overall sequence similarity to the HETEROCHROMATIN PROTEIN …

Correct expression of specific sets of genes in time and space ensures the establishment
and maintenance of cell identity, which is required for proper development of multicellular …

Seeds represent the main source of nutrients for animals and humans, and knowledge of
their biology provides tools for improving agricultural practices and managing genetic …

Epigenetics refers to heritable changes in patterns of gene expression that occur without
alterations in DNA sequence. The epigenetic mechanisms involve covalent modifications of …

Polycomb group (PcG) proteins form conserved regulatory complexes that modify chromatin
to repress the genes that are not required in a specific differentiation status [1]. In animals …
