Population genomics in Arabidopsis thaliana uncovers an extensive repertoire of active transposable element families at the species level and reveals their importance as a source of rare alleles with large effects.
Linker histone H1 and cytosine DNA methylation in contexts other than CG explain patterns of 24 nucleotide small RNA biogenesis in Arabidopsis thaliana.
Phosphate starvation in rice induces widespread, but transient, modulation of DNA methylation near stress responsive genes that is independent from the RNA-directed DNA methylation pathway.
A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

Activation of a piRNA cluster is achieved by high temperature and without maternal inheritance of homologous piRNAs highlighting how variations of species natural habitat can become heritable and shape epigenome.
Heterochromatin is established at nucleation sites associated with open chromatin and RNA transcripts and matures into stable domains if they are found near transposable elements targeted by maternally deposited piRNAs.
To protect the germ line genome, chickens acquire new small RNA-based immune defense in response to recently endogenized retroviruses by turning a truncated provirus into a weapon.

An epigenomic analysis in mouse macrophages reveals that a highly abundant transposable element exhibits activity as an immune inducible regulatory element.

Rice transposable element polymorphisms already present in the wild ancestors are associated with transcriptional variability and have been differentially selected in indica and japonica populations.
