Retrotranspositions in orthologous regions of closely related grass species

BMC Evolutionary Biology, 2006
Background Retrotransposons are commonly occurring eukaryotic transposable elements (TEs). Among these, long terminal repeat (LTR) retrotransposons are the most abundant TEs and can comprise 50–90% of the genome in higher plants.

Telomeric retrotransposons show propensity to form G-quadruplexes in various eukaryotic species

Mobile DNA, 2023
Background Canonical telomeres (telomerase-synthetised) are readily forming G-quadruplexes (G4) on the G-rich strand. However, there are examples of non-canonical telomeres among eukaryotes where telomeric tandem repeats are invaded by specific ...

Isolation of a transcriptionally active element of high copy number retrotransposons in sweetpotato genome [PDF]

, 2004
Many plant retrotransposons have been characterized, but only three families (Tnt1, Tto1 and Tos17) have been demonstrated to be transpositionally competent.

Comprehensive In Silico Analysis of Retrotransposon Insertions within the Survival Motor Neuron Genes Involved in Spinal Muscular Atrophy

Biology, 2022
Transposable elements (TEs) are interspersed repetitive and mobile DNA sequences within the genome. Better tools for evaluating TE-derived sequences have provided insights into the contribution of TEs to human development and disease.

Lost in translation : The biogenesis of non-LTR retrotransposon proteins [PDF]

, 2013
This research was supported by UK Biotechnology and Biological Sciences Research Council (BBSRC) and the Wellcome Trust.“Young” APE-type non-LTR retrotransposons (non-LTRs) typically encode two open reading frames (ORFs 1 and 2).

A comparative investigation of nuclear DNA content and its phenotypic impacts in Silene marizii and S. latifolia [PDF]

, 2008
Considerable variation exists both within and between species in nuclear DNA content. Despite there being no obvious functional role for much of this DNA, many studies have reported phenotypic correlations with genome size at various taxonomic levels ...

Comprehensive DNA Methylation Analysis of Retrotransposons in Male Germ Cells

Cell Reports, 2015
De novo DNA methylation of retrotransposons is critical for silencing. Here, we use DNA methylation analysis to examine retrotransposons in mouse male germ cells.

Large-scale transcriptome data reveals transcriptional activity of fission yeast LTR retrotransposons

BMC Genomics, 2010
Background Retrotransposons are transposable elements that proliferate within eukaryotic genomes through a process involving reverse transcription. The numbers of retrotransposons within genomes and differences between closely related species may yield ...

Retroviral-like determinants and functions required for dimerization of Ty1 retrotransposon RNA

RNA Biology
During replication of long terminal repeat (LTR)-retrotransposons, their proteins and genome (g) RNA assemble into virus-like particles (VLPs) that are not infectious but functionally related to retroviral virions. Both virions and VLPs contain gRNA in a

Nested plant LTR retrotransposons target specific regions of other elements, while all LTR retrotransposons often target palindromes and nucleosome-occupied regions: in silico study

Mobile DNA, 2019
Background Nesting is common in LTR retrotransposons, especially in large genomes containing a high number of elements. Results We analyzed 12 plant genomes and obtained 1491 pairs of nested and original (pre-existing) LTR retrotransposons.
