The genetic similarity observed among species is normally attributed to the existence of a
common ancestor. However, a growing body of evidence suggests that the exchange of …

Background All living species contain genetic information that was once shared by their
common ancestor. DNA is being inherited through generations by vertical transmission (VT) …

The transposable IFP2 element of Trichoplusia ni was originally isolated as a host DNA
insertion in spontaneous FP mutants of Galleria mellonella or Autographa californica …

Several studies have suggested that P elements have rapidly spread through natural
populations of Drosophila melanogaster within the last four decades. This observation …

Horizontal transfer (HT), defined as the transfer of genetic material between species, is
considered to be an essential step in the 'life cycle'of transposable elements. We present a …

Transposable elements (TEs) are genomic repeated sequences that display complex
evolutionary patterns. They are usually inherited vertically, but can occasionally be …

Transposable elements (TEs) are both important drivers of genome evolution and genetic
parasites with potentially dramatic consequences for host fitness. The recent explosion of …

Motivation: Horizontal transfer of transposable (HTT) elements among eukaryotes was
discovered in the mid-1980s. As then,> 300 new cases have been described. New findings …

This review summarizes recent data on the development of non-drosophilid insect
transformation systems. The discussion focuses on one particular approach to developing …

Relatively few organisms serve as experimental material for biologists and one could argue
that of the several millions of species of plants and animals extant today, no single organism …
