The transcription machinery is required for the disassembly of the promoter-proximal H2A.Z nucleosome, contributing to the constitutive histone turnover at yeast promoters.
Virus infection in mosquitoes initiates a highly discriminatory process in which fragments of viral RNA are reverse transcribed to create DNA copies that serve as templates of small antiviral RNAs.

Helitron transposable elements, by providing high density transcription factor binding sites upstream of host genes, have diversified the heat shock response within and among Caenorhabditis species.

Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.
The cell-surface protein Stranded at second is a targeting ligand for extracellular vesicles that can deliver dArc1 capsids containing dArc1 mRNA to distant cells in vivo.
Mathieu Hénault, Souhir Marsit ... Christian R Landry
The gain of transposable elements in yeast hybrids does not scale with genetic divergence levels and is most impacted by structural variations and multiple aspects of individual hybrid genetic backgrounds.

Disentangling the different selective forces shaping the evolutionary dynamics of transposable elements (TEs) in the wild grass Brachypodium distachyon.
