Environmental stress and transposons in plants [PDF]
, 2022 Transposons were once thought to be junk repetitive DNA in the genome. However, their importance gradually became apparent as it became clear that they regulate gene expression, which is essential for organisms to survive, and that they are important ...

Evolution of piggyBac Transposons in Apoidea
Insects, 2023 In this study, we investigated the presence of piggyBac (PB) transposons in 44 bee genomes from the Apoidea order, which is a superfamily within the Hymenoptera, which includes a large number of bee species crucial for pollination.

Distinct mechanisms determine transposon inheritance and methylation via small interfering RNA and histone modification. [PDF]
PLoS Biology, 2003 Heritable, but reversible, changes in transposable element activity were first observed in maize by Barbara McClintock in the 1950s. More recently, transposon silencing has been associated with DNA methylation, histone H3 lysine-9 methylation (H3mK9 ...

The relationship of lamins with epigenetic factors during aging
Вавиловский журнал генетики и селекции, 2022 The key factor of genome instability during aging is transposon dysregulation. This may be due to senile changes in the expression of lamins, which epigenetically modulate transposons. Lamins directly physically interact with transposons.

Insects, 2023 Natural transposons (NTs) represent mobile DNA sequences found in both prokaryotic and eukaryotic genomes. Drosophila melanogaster (the fruit fly) is a eukaryotic model organism with NTs standing for about 20% of its genome and has contributed ...

On transposons and totipotency [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2020 Our perception of the role of the previously considered ‘selfish’ or ‘junk’ DNA has been dramatically altered in the past 20 years or so. A large proportion of this non-coding part of mammalian genomes is repetitive in nature, classified as either satellites or transposons. While repetitive elements can be termed selfish in terms of their amplification,

Mobile DNA, 2019 Abstract Transposable elements in prokaryotes are found in many forms and therefore a robust nomenclature system is needed in order to allow researchers to describe and search for them in publications and databases. Here we provide an update on The Transposon Registry which allocates numbers to any prokaryotic transposable element ...

IS481EU Shows a New Connection between Eukaryotic and Prokaryotic DNA Transposons
Biology, 2023 DDD/E transposase gene is the most abundant gene in nature and many DNA transposons in all three domains of life use it for their transposition. A substantial number of eukaryotic DNA transposons show similarity to prokaryotic insertion sequences (ISs ...

Nonhomologous recombination: bacterial transposons
, 2021 International audienceTransposons, also called “jumping genes” are DNA fragments capable of moving/transposing from one locus to another within or between genomes. Transposons are ubiquitous and are present in all kingdoms of life. They can be present as
