Recognition and silencing of a new transposable element [PDF]
Nature CommunicationsGenomes constantly face threats from transposable elements (TEs) and other genomic parasites. While the silencing of existing TE has been well studied, little is known about how cells recognize new invading TEs that they have not previously encountered ...

Dynamic transposable element expression during Hydra head regeneration [PDF]
Mobile DNATransposable elements (TEs) contribute to genome expansions, gene duplications, and the evolution of gene regulatory networks. Recent work has highlighted the role of TE domestication in contributing to regulatory programs during animal development ...

Current Biology, 2022 Transposable elements are known by many names, including 'transposons', 'interspersed repeats', 'selfish genetic elements', 'jumping genes', and 'parasitic DNA', but here we will refer to them simply as transposable elements. Many biologists will have heard of transposable elements and their ability to transpose (change position) within the genome. But

Transposable element landscapes in aging Drosophila.
PLoS Genetics, 2022 Genetic mechanisms that repress transposable elements (TEs) in young animals decline during aging, as reflected by increased TE expression in aged animals. Does increased TE expression during aging lead to more genomic TE copies in older animals?

Whole genome resequencing reveals natural target site preferences of transposable elements in Drosophila melanogaster. [PDF]
PLoS ONE, 2012 Transposable elements are mobile DNA sequences that integrate into host genomes using diverse mechanisms with varying degrees of target site specificity.

Inference of transposable element ancestry. [PDF]
PLoS Genetics, 2014 Most common methods for inferring transposable element (TE) evolutionary relationships are based on dividing TEs into subfamilies using shared diagnostic nucleotides.

Frontiers in Plant Science, 2022 Rose (Rosa sp.) flowers have a rich diversity of colors resulting from the differential accumulation of anthocyanins, flavonols, and carotenoids. However, the genetic and molecular determinants of the red-petal trait in roses remains poorly understood ...

Transposable elements in Drosophila [PDF]
Mobile DNA, 2020 AbstractDrosophila has been studied as a biological model for many years and many discoveries in biology rely on this species. Research on transposable elements (TEs) is not an exception. Drosophila has contributed significantly to our knowledge on the mechanisms of transposition and their regulation, but above all, it was one of the first organisms on

Transposable elements in individual genotypes of Drosophila simulans
Ecology and Evolution, 2020 Transposable elements are abundant, dynamic components of the genome that affect organismal phenotypes and fitness. In Drosophila melanogaster, they have increased in abundance as the species spread out of Africa, and different populations differ in ...
