Defending the genome from the enemy within:mechanisms of retrotransposon suppression in the mouse germline [PDF]
, 2013 The viability of any species requires that the genome is kept stable as it is transmitted from generation to generation by the germ cells. One of the challenges to transgenerational genome stability is the potential mutagenic activity of transposable ...

Small RNA pathways in mammalian oocytes. [PDF]
FEBS Open BioThree distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

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).

Current Plant Biology, 2014 Retrotransposons are major components of higher plant genomes, and long terminal repeat (LTR) retrotransposons are especially predominant. Thus, numerous LTR retrotransposon families with high copy numbers exist in most plant genomes.

Short-term mutagenicity test by using IRAP molecular marker in rice grown under herbicide treatment
Biotechnology & Biotechnological Equipment, 2018 Rice is an economically important plant as well as a model organism. The rice genome consists of 35% retrotransposons. Although most of the retrotransposons are inactivated through evolutionary processes, they can be activated under various biotic and ...

R-loop landscape in mature human sperm: Regulatory and evolutionary implications
Frontiers in Genetics, 2023 R-loops are three-stranded nucleic acid structures consisting of an RNA:DNA hybrid and a displaced DNA strand. While R-loops pose a potential threat to genome integrity, they constitute 5% of the human genome.
