BackgroundThe importance of transposable elements (TEs) in the genomic remodeling and chromosomal rearrangements that accompany lineage diversification in vertebrates remains the subject of debate. The major impediment to understanding the roles of TEs in genome evolution is the lack of comparative and integrative analyses on complete taxonomic groups. To help overcome this problem, we have focused on the Antarctic teleost genus Trematomus (Notothenioidei: Nototheniidae), as they experienced… 
Insertion Hot Spots of DIRS1 Retrotransposon and Chromosomal Diversifications among the Antarctic Teleosts Nototheniidae
TLDR
The strong intrafamily TE conservation and wide distribution across species of the whole family suggest an ancestral acquisition with potential secondary losses in some lineages, including the Trematomus, the plunderfishes, and the icefishes.
Multiple independent chromosomal fusions accompanied the radiation of the Antarctic teleost genus Trematomus (Notothenioidei:Nototheniidae)
TLDR
Comparing the timing of acquisition of the fusions in the closely related genera Notothenia and Trematomus of the nototheniid species family, it is concluded that they exhibit distinct chromosomal evolutionary histories, which may be relevant to different speciation scenarios.
Comparative analysis of transposable elements provides insights into genome evolution in the genus Camelus
TLDR
It is revealed that the distribution of transposable elements across camelid genomes is approximately similar, and a characterization of TE content in four camelid species is presented to contribute to developing a better understanding of camelid genome architecture and evolution.
Movement of transposable elements contributes to cichlid diversity
TLDR
The study suggests that TEs may contribute to key regulatory changes, and may facilitate rapid phenotypic change and possibly speciation in African cichlids.
Movement of transposable elements contributes to cichlid diversity
TLDR
This study suggests that TEs may be an important driver of key regulatory changes, facilitating rapid phenotypic change and possibly speciation in African cichlids.
Evolution and diversity of transposable elements in fish genomes
TLDR
This study suggests CR1 distribution in fish genomes to be obviously regular, and provides new clues concerning important events in vertebrate evolution.
Why did the Tc1-like elements of mollusks acquired the spliceosomal introns?
TLDR
A new group of Tc1-like elements in the mollusks is identified, which is named TLEWI, and the hypothesis of co-optation of TleWI gene by the bivalves is considered.
Prokaryotic and Eukaryotic Horizontal Transfer of Sailor (DD82E), a New Superfamily of IS630-Tc1-Mariner DNA Transposons
TLDR
A new superfamily of IS630-Tc1-mariner (ITm) DNA transposons, termed Sailor, is identified, that is characterized by a DD82E catalytic domain and is distinct from all previously known superfamilies of the ITm group.
Transposable elements in vertebrates: species evolution and environmental adaptation
TLDR
The importance of TEs in creating new regulatory sequences and genetic innovations extremely useful for diversification of vertebrates is highlighted and an increasing number of evidence suggests a link between TEs and environment.
The Tc1-like elements with the spliceosomal introns in mollusk genomes
TLDR
The study of 19 mollusk genomes revealed a new group of ITm superfamily elements, which are characterized by the low copy number, the lack of terminal inverted repeats, the catalytic domain with DD36E signature and the presence of spliceosomal introns in transposase coding sequence, which will facilitate the understanding of the mechanisms of TE domestication by the host genome.

Genome differentiation in a species pair of coregonine fishes: an extremely rapid speciation driven by stress-activated retrotransposons mediating extensive ribosomal DNA multiplications
TLDR
Genetic consequences of a rapid ecological speciation on the level undetectable by neither sequence nor karyotype analysis are demonstrated and causal interplay between genome differentiation, retrotransposons (re)activation and environmental conditions may become a topic to be explored in a broader genomic context in future evolutionary studies.
LTR-Retrotransposons in R. exoculata and Other Crustaceans: The Outstanding Success of GalEa-Like Copia Elements
TLDR
The results support the hypothesis of the Copia retrotransposon scarcity in metazoans compared to Gypsy elements and identify 35 Copia and 46 Gypsy families in 15 and 18 crustacean species, respectively.
DIRS1-like retrotransposons are widely distributed among Decapoda and are particularly present in hydrothermal vent organisms
TLDR
The first degenerate primers designed to look specifically for DIRS1-like retrotransposons are provided, allowing for revealing for the first time a widespread distribution of these elements among a large phylum, here the order Decapoda.
Evolutionary dynamics of retrotransposable elements Rex1, Rex3 and Rex6 in neotropical cichlid genomes
TLDR
The distribution of Rex elements in cichlid genomes suggests that such elements are under the action of evolutionary mechanisms that lead to their accumulation in particular chromosome regions, mostly in heterochromatins.
Transposable elements as drivers of genomic and biological diversity in vertebrates
TLDR
Observations indicate that transposable elements are major drivers of genomic and biological diversity in vertebrates, with possible important roles in speciation and major evolutionary transitions.
Chromosome Evolution in African Cichlid Fish: Contributions from the Physical Mapping of Repeated DNAs
TLDR
The comparative chromosome mapping of the ROn-1 SINE-like element and BAC-C4E09 shows that the repeated sequences have been maintained among tilapiine, haplochromine and hemichromine fishes and has demonstrated the homology of the largest chromosomes among these groups.
Cytogenetic Mapping of the Retroelements Rex1, Rex3 and Rex6 among Cichlid Fish: New Insights on the Chromosomal Distribution of Transposable Elements
TLDR
Comparison analysis suggests that Rex elements could differ in their chromosomal distribution among different fish groups or species and that intrinsic aspects of the genomes could influence the spread, accumulation or elimination of TEs.
Genome-wide comparative analysis of copia retrotransposons in Triticeae, rice, and Arabidopsis reveals conserved ancient evolutionary lineages and distinct dynamics of individual copia families.
TLDR
It is estimated that half of the rice copia elements are truncated or otherwise rearranged after approximately 790,000 yr, which is almost twice the half-life of Arabidopsis elements, and wheat and barleyCopia elements appear to have a massively longer half- life, beyond the ability to estimate from the available data.
Genome dynamics and chromosomal localization of the non-LTR retrotransposons Rex1 and Rex3 in Antarctic fish
TLDR
This report is the first description and analysis of retrotransposable elements in Antarctic fish genomes and suggests the presence of autosomal and gonosomal regions of preferential accumulation for different types of repeated elements in notothenioid genomes.
