Heterochromatin in plant meiosis

open access: yesNucleus
Heterochromatin 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.

The Cell Biology of Heterochromatin

open access: yesCells, 2022
A conserved feature of virtually all higher eukaryotes is that the centromeres are embedded in heterochromatin. Here we provide evidence that this tight association between pericentric heterochromatin and the centromere is essential for proper metaphase ...

Heterochromatin revisited [PDF]

open access: yesNature 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.

Imaging the response to DNA damage in heterochromatin domains reveals core principles of heterochromatin maintenance

open access: yesNature Communications, 2021
The heterochromatin compartment is key for genome stability and cell fate transitions. Here, by tracking the heterochromatin response to UV damage in real time, the authors reveal how heterochromatin features are preserved following a genotoxic stress ...

How HP1 Post-Translational Modifications Regulate Heterochromatin Formation and Maintenance [PDF]

open access: yesCells, 2020
Heterochromatin Protein 1 (HP1) is a highly conserved protein that has been used as a classic marker for heterochromatin. HP1 binds to di- and tri-methylated histone H3K9 and regulates heterochromatin formation, functions and structure.

The highly dynamic heterochromatin protein Swi6 mediates degradation of heterochromatic transcripts [PDF]

open access: yes, 2014
The aim of my thesis was to investigate the mechanism of heterochromatin repression mediated by heterochromatin protein Swi6 in S. pombe. Research over the years challenged the view of heterochromatin as a static and transcriptionally inert structure ...

Transcriptional gene silencing mutants in "Arabidopsis thaliana" and their impact on nuclear architecture and heterochromatin organization [PDF]

open access: yes, 2004
The epigenetic regulation of gene expression is defined by covalent modifications of DNA and histone tails as well as by chromatin structure and nuclear architecture.

Genome mapping and characterization of the Anopheles gambiae heterochromatin

open access: yesBMC Genomics, 2010
Background Heterochromatin plays an important role in chromosome function and gene regulation. Despite the availability of polytene chromosomes and genome sequence, the heterochromatin of the major malaria vector Anopheles gambiae has not been mapped and

Epigenetic gene silencing by heterochromatin primes fungal resistance [PDF]

open access: yes, 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 ...
