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.
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.
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.
Soon after fertilisation, a critical portion of the embryonic genome is switched on through the actions of maternally inherited Stella, in part through controlling the activation of transposable elements.
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.
