Additional ORFs in Plant LTR-Retrotransposons. [PDF]
Front Plant Sci, 2020 LTR-retrotransposons share a common genomic organization in which the 5' long terminal repeat (LTR) is followed by the gag and pol genes and terminates with the 3' LTR. Although GAG-POL-encoded proteins are considered sufficient to accomplish the LTR-retrotransposon transposition, a number of elements carrying additional open reading frames (aORF) have

Skipper, an LTR retrotransposon of Dictyostelium [PDF]
Nucleic Acids Research, 1998 The complete sequence of a retrotransposon from Dictyostelium discoideum , named skipper , was obtained from cDNA and genomic clones. The sequence of a nearly full-length skipper cDNA was similar to that of three other partially sequenced cDNAs. The corresponding retrotransposon is represented in approximately 15-20 copies and is abundantly transcribed.

Identification of an active LTR retrotransposon in rice [PDF]
The Plant Journal, 2009 SummaryTransposable elements are ubiquitous components of plant genomes. When active, these mobile elements can induce changes in the genome at both the structural and functional levels. Availability of the complete genome sequence for several model plant species provides the opportunity to study TEs in plants at an unprecedented scale.

RetrOryza: a database of the rice LTR-retrotransposons [PDF]
Nucleic Acids Research, 2007 Long terminal repeat (LTR)-retrotransposons comprise a significant portion of the rice genome. Their complete characterization is thus necessary if the sequenced genome is to be annotated correctly. In addition, because LTR-retrotransposons can influence the expression of neighboring genes, the complete identification of these elements in the rice ...

PLoS ONE, 2011 Transposable elements with long terminal direct repeats (LTR TEs) are one of the best studied groups of mobile elements. They are ubiquitous elements present in almost all eukaryotic genomes. Their number and state of conservation can be a highlight of genome dynamics.

Activation of a LTR-retrotransposon by telomere erosion [PDF]
Proceedings of the National Academy of Sciences, 2003 Retrotransposons can facilitate repair of broken chromosomes, and therefore an important question is whether the host can activate retrotransposons in response to chromosomal lesions. Here we show that Ty1 elements, which are LTR-retrotransposons in Saccharomyces cerevisiae , are mobilized when DNA lesions are ...

Chromodomains and LTR retrotransposons in plants [PDF]
Communicative & Integrative Biology, 2009 A chromodomain is a domain contained in various proteins involved in chromatin remodeling and the regulation of gene expression in eukaryotes during development. Chromodomains perform a wide range of diverse functions including chromatin targeting and interactions between different proteins, RNA and DNA.

Non-LTR retrotransposons and microsatellites [PDF]
Mobile Genetic Elements, 2013 The human genome is laden with both non-LTR (long-terminal repeat) retrotransposons and microsatellite repeats. Both types of sequences are able to, either actively or passively, mutagenize the genomes of human individuals and are therefore poised to dynamically alter the human genomic landscape across generations.

LTR retrotransposons and the evolution of dosage compensation in Drosophila [PDF]
BMC Molecular Biology, 2008 Dosage compensation in Drosophila is the epigenetic process by which the expression of genes located on the single X-chromosome of males is elevated to equal the expression of X-linked genes in females where there are two copies of the X-chromosome. While epigenetic mechanisms are hypothesized to have evolved originally to silence transposable elements,

The diversity of LTR retrotransposons.
Genome biology, 2004 Eukaryotic genomes are full of long terminal repeat (LTR) retrotransposons. Although most LTR retrotransposons have common structural features and encode similar genes, there is nonetheless considerable diversity in their genomic organization, reflecting the different strategies they use to proliferate within the genomes of their hosts.
