PLoS Genetics, 2019 H3K9 methylation (H3K9me) is a conserved marker of heterochromatin, a transcriptionally silent chromatin structure. Knowledge of the mechanisms for regulating heterochromatin distribution is limited.

FISH mapping and molecular organization of the major repetitive sequences of tomato [PDF]
, 2008 This paper presents a bird's-eye view of the major repeats and chromatin types of tomato. Using fluorescence in-situ hybridization (FISH) with Cot-1, Cot-10 and Cot-100 DNA as probes we mapped repetitive sequences of different complexity on pachytene ...

Histone crosstalk directed by H2B ubiquitination is required for chromatin boundary integrity [PDF]
, 2011 Genomic maps of chromatin modifications have provided evidence for the partitioning of genomes into domains of distinct chromatin states, which assist coordinated gene regulation.

Epigenetic gene silencing by heterochromatin primes fungal resistance [PDF]
, 2021 Genes embedded in H3 lysine 9 methylation (H3K9me)–dependent heterochromatin are transcriptionally silenced. In fission yeast, Schizosaccharomyces pombe, H3K9me-mediated heterochromatin can be transmitted through cell division provided the ...

Mediator directs co-transcriptional heterochromatin assembly by RNA interference-dependent and -independent pathways. [PDF]
PLoS Genetics, 2013 Heterochromatin at the pericentromeric repeats in fission yeast is assembled and spread by an RNAi-dependent mechanism, which is coupled with the transcription of non-coding RNA from the repeats by RNA polymerase II. In addition, Rrp6, a component of the

HP1 reshapes the nucleosome core to promote phase separation of heterochromatin
Nature, 2019 Heterochromatin affects genome function at many levels. It enables heritable gene repression, maintains chromosome integrity and provides mechanical rigidity to the nucleus1,2.

Sex Differences in Drosophila melanogaster Heterochromatin Are Regulated by Non-Sex Specific Factors. [PDF]
PLoS ONE, 2015 The eukaryotic genome is assembled into distinct types of chromatin. Gene-rich euchromatin has active chromatin marks, while heterochromatin is gene-poor and enriched for silencing marks.

Ccq1–Raf2 interaction mediates CLRC recruitment to establish heterochromatin at telomeres
Life Science Alliance, 2021 This study unveils a role of Ccq1–Raf2 interaction in CLRC recruitment to establish heterochromatin at telomeres, providing a positive feedback mechanism between shelterin and CLRC for subtelomeric heterochromatin assembly.

Drosophila HP1c is regulated by an auto-regulatory feedback loop through its binding partner Woc [PDF]
, 2009 HP1 is a major component of chromatin and regulates gene expression through its binding to methylated histone H3. Most eukaryotes express at least three isoforms of HP1 with similar domain architecture.
