Retrotransposons as pathogenicity factors of the plant pathogenic fungus Botrytis cinerea
Genome Biology, 2021 Background Retrotransposons are genetic elements inducing mutations in all domains of life. Despite their detrimental effect, retrotransposons can become temporarily active during epigenetic reprogramming and cellular stress response, which may ...

Current Biology, 2012 June 27, 1970 was a significant day for our understanding of both the flow of information in biological systems and the evolution of eukaryotic genomes as this was the day that Nature published back-to-back papers reporting the discovery of an enzyme that copies RNA into DNA. This soon became known as reverse transcriptase and the RNA tumour viruses in

Agronomy, 2022 Pennisetum purpureum is a potential species for biofuel production. Characterization and chromosomal distribution of retrotransposons could enhance the comprehension of the role and dynamics of the repetitive elements in plants.

Long interspersed element-1 (LINE-1): passenger or driver in human neoplasms? [PDF]
PLoS Genetics, 2013 LINE-1 (L1) retrotransposons make up a significant portion of human genomes, with an estimated 500,000 copies per genome. Like other retrotransposons, L1 retrotransposons propagate through RNA sequences that are reverse transcribed into DNA sequences ...

The Singular Evolution of Olea Genome Structure
Frontiers in Plant Science, 2022 The current view of plant genome evolution proposes that genome size has mainly been determined by polyploidisation and amplification/loss of transposons, with a minor role played by other repeated sequences, such as tandem repeats.

Caryologia, 2020 Long terminal repeat retrotransposons have a main role in shaping the structure of plant genomes. We used available genomic resources to study as several factors affect the expression of long terminal repeat retrotransposons in Populus trichocarpa.

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 ...

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.

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.
