Genome-wide profiling and functional analyses reveal a network of heterochromatin and small RNA factors that silences repetitive elements and prevents genotoxic stress to ensure fertility.

Suv39h1 chromodomain possesses nucleic acid-binding activity and this activity is coupled with its H3K9 methylation recognition in assembling heterochromatin.

Epigenetic restriction of herpes simplex virus occurs in a biphasic manner, in which ATRX maintains viral heterochromatin after an initial phase of chromatin deposition.

Genome-wide identification of long non-coding RNAs produced by RNA Polymerase V identifies their role in heterochromatin maintenance on the boundaries of repressed regions.

Origin recognition complex-associated (ORCA) is crucial for the stability of the Histone H3 lysine 9 methyltransferase megacomplex, which is essential for heterochromatin organization.

Linker histone H1 and cytosine DNA methylation in contexts other than CG explain patterns of 24 nucleotide small RNA biogenesis in Arabidopsis thaliana.

Heterochromatin spreading in fission yeast predominantly produces intergenerationally unstable outcomes, requiring an accessory element that represses histone turnover.

The efficient deployment of RdDM for transposon silencing is hierarchically controlled by the linker histone H1.

Fission yeast loses its heterochromatin stability at mating-type locus under high temperature due to compromised binding between heterochromatin protein Swi6^HP1 and Atf1.

Heterochromatic sequences evolve rapidly, as do ZAD-ZNF genes-encoding proteins involved in heterochromatin functions, explaining why evolutionarily dynamic ZAD-ZNF genes are more likely to be essential in Drosophila.
