Fully functional regulatory elements can arise rapidly from transposable elements via a novel route where non-allelic gene conversion can act to speed up the evolutionary fine-tuning of regulatory elements.

Genetic and epigenetic editing experiments establish causal links between transposon-derived enhancers and gene regulation in mouse embryonic and extraembryonic lineages.
The ability of transposable elements to epigenetically influence adjacent genes impacts genome evolution by driving substantial variation in transposon numbers between species.
The ultimate driver for the substantial between-species difference in the success of transposable elements, the widely distributed genetic parasite, may lie in the overall chromatin environment.

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.

An investigation of transposable element evolution in a group of long-term asexual animals shows that many of the predicted effects of asexuality are not observed.
Fine mapping of transposable element presence/absence variation amongst 216 Arabidopsis strains uncovers widespread novel genetic diversity that underlies differences in transcription and DNA methylation patterns.
The activation of transposable elements and relaxed purifying selection underpin an incipient expansion of the genome in populations of a major wheat pathogen.
