Establishment of cell-based transposon-mediated transgenesis in cattle
(Elsevier Science Inc, 2016-04)
Transposon-mediated transgenesis is a well-established tool for genome modification in small animal models. However, translation of this active transgenic method to large animals warrants further investigations. Here, the ...
Organization of Repeated DNA Elements in the Genome of the Cichlid Fish Cichla kelberi and Its Contributions to the Knowledge of Fish Genomes
(Karger, 2009-01-01)
Repeated DNA elements have been extensively applied as physical chromosome markers in comparative studies for the identification of chromosomal rearrangements, the identification of sex chromosomes, chromosome evolution ...
Revisiting horizontal transfer of transposable elements in Drosophila
(Nature Publishing Group, 2008-06-01)
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 broad overview of suspected cases of ...
New mariner elements in Anastrepha species (Diptera: Tephritidae)
(2011-09-01)
Mariner-like elements (MLE) are members from class II of transposable elements also known as DNA transposons. These elements have a wide distribution among different groups of organisms, including insects, which can be ...
The contribution of transposable elements to Bos taurus gene structure
(Elsevier B.V., 2007-04-01)
In an effort to identify the contribution of TEs to bovine genome evolution, the abundance, distribution and insertional orientation of TEs were examined in all bovine nuclear genes identified in sequence build 2.1 (released ...
Molecular analysis of a mutant Anticarsia gemmatalis multiple nucleopolyhedrovirus (AgMNPV) shows an interruption of an inhibitor of apoptosis gene (iap-3) by a new class-II piggyBac-related insect transposon
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
A new piggyBac-related transposable element (TE) was found in the genome of a mutant Anticarsia gemmatalis multiple nucleopolyhedrovirus interrupting an inhibitor of apoptosis gene. This mutant virus induces apoptosis upon ...
DNA transposon invasion and microsatellite accumulation guide W chromosome differentiation in a Neotropical fish genome
(Springer, 2019-12-01)
Sex chromosome differentiation is subject to independent evolutionary processes among different lineages. The accumulation of repetitive DNAs and consequent crossing-over restriction guide the origin of the heteromorphic ...
Report of a chimeric origin of transposable elements in a bovine-coding gene
(2008-04-22)
Despite the wide distribution of transposable elements (TEs) in mammalian genomes, part of their evolutionary significance remains to be discovered. Today there is a substantial amount of evidence showing that TEs are ...
The protist Trichomonas vaginalis harbors multiple lineages of transcriptionally active Mutator-like elements
(Biomed Central LtdLondonInglaterra, 2009)
UV-B radiation induces Mu element somatic transposition in maize
(Oxford University Press, 2013-11)
The maize Mutator (MuDR/Mu) transposon family is the most active DNA transposon inplants (Lisch 2002). The Mu family contains diverse elements, all sharing similar ~215 bpterminal inverted repeats (TIRs). MuDR is the ...
