The Green Valley of Drosophila melanogaster Constitutive Heterochromatin: Protein-Coding Genes Involved in Cell Division Control. [PDF]
Constitutive heterochromatin represents a significant fraction of eukaryotic genomes (10% in Arabidopsis, 20% in humans, 30% in D. melanogaster, and up to 85% in certain nematodes) and shares similar genetic and molecular properties in animal and plant ...

Constitutive heterochromatin formation and transcription in mammals. [PDF]
Constitutive heterochromatin, mainly formed at the gene-poor regions of pericentromeres, is believed to ensure a condensed and transcriptionally inert chromatin conformation.

Suv39h1 links the SUMO pathway to constitutive heterochromatin. [PDF]
The Suv39h lysine methyltransferases, known as key enzymes responsible for histone H3 lysine 9 methylation, are critical for heterochromatin protein 1 enrichment at constitutive heterochromatin.

The Polycomb Repressive Complex 1 Protein BMI1 Is Required for Constitutive Heterochromatin Formation and Silencing in Mammalian Somatic Cells. [PDF]
Background: BMI1 silences the expression of genes located at the facultative heterochromatin. Results: BMI1 is abundant at repetitive genomic regions, including the pericentromeric heterochromatin (PCH), where it is required for compaction and silencing.

Position effect variegation and viability are both sensitive to dosage of constitutive heterochromatin in Drosophila. [PDF]
The dosage effect of Y-chromosome heterochromatin on suppression of position effect variegation (PEV) has long been well-known in Drosophila. The phenotypic effects of increasing the overall dosage of Y heterochromatin have also been demonstrated ...

Histone hypoacetylation is required to maintain late replication timing of constitutive heterochromatin [PDF]
The replication of the genome is a spatio-temporally highly organized process. Yet, its flexibility throughout development suggests that this process is not genetically regulated.
