Abstract Chicken repeat 1 (CR1) retroposons are the most abundant superfamily of
transposable elements in the genomes of birds, crocodilians, and turtles. However, CR1 …

Background There is growing recognition that horizontal DNA transfer, a process known to
be common in prokaryotes, is also a significant source of genomic variation in eukaryotes …

Both ZeBrafish (ZB), a recently identified DNA transposon in the zebrafish genome, and SB,
a reconstructed transposon originally discovered in several fish species, are known to …

Transposable elements (TEs) are mobile genetic elements in the genome and broadly
distributed across both prokaryotes and eukaryotes, and play an important role in shaping …

Recent advances in nucleic acid sequencing technology are creating a diverse landscape
for the analysis of horizontal transfer in complete genomes. Previously limited to …

Background A fundamental concept in biology is that heritable material, DNA, is passed from
parent to offspring, a process called vertical gene transfer. An alternative mechanism of …

Molecular domestications of transposable elements have occurred repeatedly during the
evolution of eukaryotes. Vertebrates, especially mammals, possess numerous single copy …

Background Long terminal repeat (LTR) retrotransposons are a widespread kind of
transposable element present in eukaryotic genomes. They are a major factor in genome …

The contribution of the transposons' promoter in the horizontal transfer process is quite
overlooked in the scientific literature. To shed light on this aspect we have mimicked the …

In the genome of Artiodactyla (cow, sheep, pigs, camels, and whales), a major retroposon
group originated from a presumable horizontal transfer of BovB, a retrotransposon-like …
