Stress-induced activation of heterochromatic transcription. [PDF]

PLoS Genetics, 2010
Constitutive heterochromatin comprising the centromeric and telomeric parts of chromosomes includes DNA marked by high levels of methylation associated with histones modified by repressive marks.

On the evolution of Yeti, a Drosophila melanogaster heterochromatin gene. [PDF]

PLoS ONE, 2014
Constitutive heterochromatin is a ubiquitous and still unveiled component of eukaryotic genomes, within which it comprises large portions. Although constitutive heterochromatin is generally considered to be transcriptionally silent, it contains a ...

On the relations of phase separation and Hi-C maps to epigenetics [PDF]

Royal Society Open Science, 2020
The relationship between compartmentalization of the genome and epigenetics is long and hoary. In 1928, Heitz defined heterochromatin as the largest differentiated chromatin compartment in eukaryotic nuclei.

Local chromatin context regulates the genetic requirements of the heterochromatin spreading reaction.

PLoS Genetics, 2022
Heterochromatin spreading, the expansion of repressive chromatin structure from sequence-specific nucleation sites, is critical for stable gene silencing.

Imaging the Response to DNA Damage in Heterochromatin Domains

Frontiers in Cell and Developmental Biology, 2022
The eukaryotic genome is assembled in a nucleoprotein complex called chromatin, whose organization markedly influences the repair of DNA lesions. For instance, compact chromatin states, broadly categorized as heterochromatin, present a challenging ...

Histone variants shape chromatin states in Arabidopsis

eLife, 2023
How different intrinsic sequence variations and regulatory modifications of histones combine in nucleosomes remain unclear. To test the importance of histone variants in the organization of chromatin we investigated how histone variants and histone ...
