Epigenetic gene silencing by heterochromatin primes fungal resistance [PDF]
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 ...

Candida albicans repetitive elements display epigenetic diversity and plasticity [PDF]
Transcriptionally silent heterochromatin is associated with repetitive DNA. It is poorly understood whether and how heterochromatin differs between different organisms and whether its structure can be remodelled in response to environmental signals. Here,

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]
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 ...

Mediator directs co-transcriptional heterochromatin assembly by RNA interference-dependent and -independent pathways. [PDF]
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

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

Sex Differences in Drosophila melanogaster Heterochromatin Are Regulated by Non-Sex Specific Factors. [PDF]
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
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.

Mechanisms of heterochromatin subnuclear localization. [PDF]
Transcriptionally repressed heterochromatin becomes the dominant form of chromatin in most terminally differentiated cells. Moreover, in most cells, at least one class of heterochromatin is positioned adjacent to the nuclear lamina.

A simulation model of heterochromatin formation at submolecular detail
Summary: Heterochromatin is a physical state of the chromatin fiber that maintains gene repression during cell development. Although evidence exists on molecular mechanisms involved in heterochromatin formation, a detailed structural mechanism of ...
