Retrotransposons and Telomeres
Biochemistry (Moscow), 2023 Abstract Transposable elements (TEs) comprise a significant part of eukaryotic genomes being a major source of genome instability and mutagenesis. Cellular defense systems suppress the TE expansion at all stages of their life cycle.

Stress Induced Activation of LTR Retrotransposons in the Drosophila melanogaster Genome
Life, 2023 Background: Retrotransposons with long terminal repeats (LTR retrotransposons) are widespread in all groups of eukaryotes and are often both the cause of new mutations and the source of new sequences.

BMC Genomics, 2021 Background Long Terminal Repeat retrotransposons (LTR retrotransposons) are mobile genetic elements composed of a few genes between terminal repeats and, in some cases, can comprise over half of a genome’s content.

The Journal of Reproduction and Development, 2022 In the male germline, the machinery to repress retrotransposons that threaten genomic integrity via the piRNA pathway is established in gonocytes. It has been reported that disruption of the piRNA pathway leads to activation of retrotransposons and ...

Retrotransposons in pluripotent stem cells
Cell Regeneration, 2020 Transposable elements constitute about half of the mammalian genome, and can be divided into two classes: the class I (retrotransposons) and the class II (DNA transposons).

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 ...

LTR-retrotransposons in R. exoculata and other crustaceans [PDF]
, 2013 Transposable elements are major constituents of eukaryote genomes and have a great impact on genome structure and stability. They can contribute to the genetic diversity and evolution of organisms. Knowledge of their distribution among several genomes is

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
