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 ...

SUV39 SET domains mediate crosstalk of heterochromatic histone marks
eLife, 2021 The SUV39 class of methyltransferase enzymes deposits histone H3 lysine 9 di- and trimethylation (H3K9me2/3), the hallmark of constitutive heterochromatin.

Nde1 is required for heterochromatin compaction and stability in neocortical neurons
iScience, 2022 Summary: The NDE1 gene encodes a scaffold protein essential for brain development. Although biallelic NDE1 loss of function (LOF) causes microcephaly with profound mental retardation, NDE1 missense mutations and copy number variations are associated with

Constitutive heterochromatin polymorphism in river buffalo chromosomes
Caryologia, 1995 Constitutive heterochromatin (HC) distribution among river buffalo (Bubalus bubalis L., 2n=50) chromosomes was analyzed by using both the CBA-technique and GBA + CBA technique. CBA-banding revealed the presence of HC in the centromeric regions of all the chromosomes of the 15 animals we investigated.

CHROMOSOMAL POLYMORPHISMS OF CONSTITUTIVE HETEROCHROMATIN AND INVERSIONS IN DROSOPHILA [PDF]
Genetics, 1977 ABSTRACT A simple technique for preparing mitotic metaphases from a larval ganglion of Drosophila is described. Parallel examination of polytene and metaphase chromosome groups shows that inversion polymorphism in chromosome 3 of D.

A Modular and Customizable CRISPR/Cas Toolkit for Epigenome Editing of Cis‐regulatory Modules
Advanced Science, EarlyView.Epigenome editing surpasses genome editing in gene regulation. Modular epigenome editing frameworks are developed to interrogate cis‐regulome, enabling tunable reprogramming of cis‐elements, uncovering their epigenetic responsiveness and cross‐species portability.

HP1 recruits activity-dependent neuroprotective protein to H3K9me3 marked pericentromeric heterochromatin for silencing of major satellite repeats. [PDF]
PLoS ONE, 2011 H3 lysine 9 trimethylation (H3K9me3) is a histone posttranslational modification (PTM) that has emerged as hallmark of pericentromeric heterochromatin.
