Heterochromatin: Guardian of the Genome [PDF]
Annual Review of Cell and Developmental Biology, 2018 Constitutive heterochromatin is a major component of the eukaryotic nucleus and is essential for the maintenance of genome stability. Highly concentrated at pericentromeric and telomeric domains, heterochromatin is riddled with repetitive sequences and has evolved specific ways to compartmentalize, silence, and repair repeats.

Heterochromatin in plant meiosis
NucleusHeterochromatin is an organizational property of eukaryotic chromosomes, characterized by extensive DNA and histone modifications, that is associated with the silencing of transposable elements and repetitive sequences.

Global regulation of heterochromatin spreading by Leo1 [PDF]
Open Biology, 2015 Heterochromatin plays important roles in eukaryotic genome regulation. However, the repressive nature of heterochromatin combined with its propensity to self-propagate necessitates robust mechanisms to contain heterochromatin within defined boundaries ...

Heterochromatin Formation Promotes Longevity and Represses Ribosomal RNA Synthesis [PDF]
PLoS Genetics, 2012 Organismal aging is influenced by a multitude of intrinsic and extrinsic factors, and heterochromatin loss has been proposed to be one of the causes of aging. However, the role of heterochromatin in animal aging has been controversial.

Heterochromatin revisited [PDF]
Nature Reviews Genetics, 2007 The formation of heterochromatin, which requires methylation of histone H3 at lysine 9 and the subsequent recruitment of chromodomain proteins such as heterochromatin protein HP1, serves as a model for the role of histone modifications and chromatin assembly in epigenetic control of the genome.

Epigenetics & Chromatin, 2022 Budding yeast Saccharomyces cerevisiae and fission yeast Schizosaccharomyces pombe are good models for heterochromatin study. In S. pombe, H3K9 methylation and Swi6, an ortholog of mammalian HP1, lead to heterochromatin formation. However, S.

The proper splicing of RNAi factors is critical for pericentric heterochromatin assembly in fission yeast. [PDF]
PLoS Genetics, 2014 Heterochromatin preferentially assembles at repetitive DNA elements, playing roles in transcriptional silencing, recombination suppression, and chromosome segregation.

Constitutive Heterochromatin in Eukaryotic Genomes: A Mine of Transposable Elements
Cells, 2022 Transposable elements (TEs) are abundant components of constitutive heterochromatin of the most diverse evolutionarily distant organisms. TEs enrichment in constitutive heterochromatin was originally described in the model organism Drosophila ...

Different behaviour of C-banded peri-centromeric heterochromatin between sex chromosomes and autosomes in Polyphagan beetles [PDF]
Comparative Cytogenetics, 2019 Heterochromatin variation was studied after C-banding of male karyotypes with a XY sex formula from 224 species belonging to most of the main families of Coleoptera.

Maternal depletion of Piwi, a component of the RNAi system, impacts heterochromatin formation in Drosophila. [PDF]
PLoS Genetics, 2013 A persistent question in epigenetics is how heterochromatin is targeted for assembly at specific domains, and how that chromatin state is faithfully transmitted.
