LTR retrotransposons in fungi. [PDF]
, 2011 Transposable elements with long terminal direct repeats (LTR TEs) are one of the best studied groups of mobile elements. They are ubiquitous elements present in almost all eukaryotic genomes.

The CACTA transposon Bot1 played a major role in Brassica genome divergence and gene proliferation [PDF]
, 2008 We isolated and characterized a Brassica C genome-specific CACTA element, which was designated Bot1 (Brassica oleracea transposon 1). After analysing phylogenetic relationships, copy numbers and sequence similarity of Bot1 and Bot1 analogues in B ...

Evolutionary Applications, 2021 Insecticide use is pervasive as a selective force in modern agroecosystems. Insect herbivores exposed to these insecticides have been able to rapidly evolve resistance to them, but how they are able to do so is poorly understood. One possible but largely

The CCCTC-binding factor (CTCF) of Drosophila contributes to the regulation of the ribosomal DNA and nucleolar stability. [PDF]
PLoS ONE, 2011 In the repeat array of ribosomal DNA (rDNA), only about half of the genes are actively transcribed while the others are silenced. In arthropods, transposable elements interrupt a subset of genes, often inactivating transcription of those genes. Little is

Zisupton--A Novel Superfamily of DNA Transposable Elements Recently Active in Fish [PDF]
Molecular Biology and Evolution, 2011 Transposable elements are widespread mobile DNA sequences able to integrate into new locations within genomes. Through transposition and recombination, they significantly contribute to genome plasticity and evolution. They can also regulate gene expression and provide regulatory and coding sequences (CDSs) for the evolution of novel gene functions.

BMC Genomics, 2017 Background Switchgrass is a crop with many desirable traits for bioenergy production. Plant genomes have high DNA methylation levels throughout genes and transposable elements and DNA methylation is known to play a role in silencing transposable elements.

Mangrove Forests: Natural Laboratories for Studying Epigenetic and Climate Changes
Frontiers in Plant Science, 2022 In the adaptation market, plants cash in the changes of their DNA (either genetic or epigenetic) to purchase fitness. Fitness is negatively affected by stressful conditions caused by climate change and well-designed studies are required to investigate ...

Precise targeted integration by a chimaeric transposase zinc-finger fusion protein [PDF]
, 2010 Transposons of the Tc1/mariner family have been used to integrate foreign DNA stably into the genome of a large variety of different cell types and organisms.

A MODEL FOR DNA SEQUENCE EVOLUTION WITHIN TRANSPOSABLE ELEMENT FAMILIES [PDF]
Genetics, 1986 ABSTRACT A quantitative model is proposed for the expected degree of relationship between copies of a family of transposable elements in a finite population of hosts. Special cases of the model (in which the process of homogenization of element copies either is or is not limited by transposition rate) are presented and illustrated, using

A complex repeated DNA sequence within the Drosophila transposable element copia [PDF]
Nucleic Acids Research, 1981 A 320 nucleotide repeated DNA sequence within the copia coding element of Drosophila melanogaster has been identified and characterized. This sequence has been localized by DNA-DNA hybridization and electron microscopic analysis of heteroduplexes to the approximate middle of the 5 kb copia coding region.
