Convergence of retrotransposons in oomycetes and plants [PDF]
Mobile DNA, 2017 Retrotransposons comprise a ubiquitous and abundant class of eukaryotic transposable elements. All members of this class rely on reverse transcriptase activity to produce a DNA copy of the element from the RNA template. However, other activities of the retrotransposon-encoded polyprotein may differ between diverse retrotransposons.

Scattered organization of the histone multigene family and transposable elements in Synbranchus
Genetics and Molecular Biology, 2014 The fish species Synbranchus marmoratus is widely distributed throughout the Neotropical region and exhibits a significant karyotype differentiation. However, data concerning the organization and location of the repetitive DNA sequences in the genomes of

The evolution of tyrosine-recombinase elements in Nematoda [PDF]
, 2014 Transposable elements can be categorised into DNA and RNA elements based on their mechanism of transposition. Tyrosine recombinase elements (YREs) are relatively rare and poorly understood, despite sharing characteristics with both DNA and RNA elements.

ADAR1 restricts LINE-1 retrotransposition [PDF]
, 2016 Adenosine deaminases acting on RNA (ADARs) are involved in RNA editing that converts adenosines to inosines in double-stranded RNAs. ADAR1 was demonstrated to be functional on different viruses exerting either antiviral or proviral effects.

LTRs of Endogenous Retroviruses as a Source of Tbx6 Binding Sites
Frontiers in Chemistry, 2017 Retrotransposons are abundant in mammalian genomes and can modulate the gene expression of surrounding genes by disrupting endogenous binding sites for transcription factors (TFs) or providing novel TFs binding sites within retrotransposon sequences ...

FISH mapping and molecular organization of the major repetitive sequences of tomato [PDF]
, 2008 This paper presents a bird's-eye view of the major repeats and chromatin types of tomato. Using fluorescence in-situ hybridization (FISH) with Cot-1, Cot-10 and Cot-100 DNA as probes we mapped repetitive sequences of different complexity on pachytene ...

Sequencing the extrachromosomal circular mobilome reveals retrotransposon activity in plants
PLoS Genetics, 2017 Retrotransposons are mobile genetic elements abundant in plant and animal genomes. While efficiently silenced by the epigenetic machinery, they can be reactivated upon stress or during development.

Distribution and conservation of the transposable element gypsy in drosophilid species
Genetics and Molecular Biology, 2007 In an attempt to understand the dynamics of transposable elements (T'S) in the genome of host species, we investigated the distribution, representativeness and conservation of DNA sequences homologous to the Drosophila melanogaster gypsy retrotransposon ...

The Chern-Simons Current in Time Series of Knots and Links in Proteins [PDF]
, 2018 A superspace model of knots and links for DNA time series data is proposed to take into account the feedback loop from docking to undocking state of protein-protein interactions. In particular, the direction of interactions between the 8 hidden states of DNA is considered.
