Insights into the genome of the ‘Loco’ Concholepas concholepas (Gastropoda: Muricidae) from low-coverage short-read sequencing: genome size, ploidy, transposable elements, nuclear RNA gene operon, mitochondrial genome, and phylogenetic placement in the family Muricidae

BMC Genomics
Background The Peruvian ‘chanque’ or Chilean ‘loco’ Concholepas concholepas is an economically, ecologically, and culturally important muricid gastropod heavily exploited by artisanal fisheries in the temperate southeastern Pacific Ocean.

Shuffling the yeast genome using CRISPR/Cas9-generated DSBs that target the transposable Ty1 elements

PLoS Genetics, 2023
Although homologous recombination between transposable elements can drive genomic evolution in yeast by facilitating chromosomal rearrangements, the details of the underlying mechanisms are not fully clarified.

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

Transposable elements and viruses as factors in adaptation and evolution: an expansion and strengthening of the TE-Thrust hypothesis [PDF]

, 2012
In addition to the strong divergent evolution and significant and episodic evolutionary transitions and speciation we previously attributed to TE-Thrust, we have expanded the hypothesis to more fully account for the contribution of viruses to TE-Thrust ...

Conversion of DNA Sequences: From a Transposable Element to a Tandem Repeat or to a Gene [PDF]

Genes, 2019
Eukaryotic genomes are rich in repetitive DNA sequences grouped in two classes regarding their genomic organization: tandem repeats and dispersed repeats. In tandem repeats, copies of a short DNA sequence are positioned one after another within the genome, while in dispersed repeats, these copies are randomly distributed.

Transposon insertion profiling by sequencing (TIPseq) for mapping LINE-1 insertions in the human genome

Mobile DNA, 2019
Background Transposable elements make up a significant portion of the human genome. Accurately locating these mobile DNAs is vital to understand their role as a source of structural variation and somatic mutation. To this end, laboratories have developed

Comprehensive analysis of the Xya riparia genome uncovers the dominance of DNA transposons, LTR/Gypsy elements, and their evolutionary dynamics

BMC Genomics
Transposable elements (TEs) are DNA sequences that can move or replicate within a genome, and their study has become increasingly important in understanding genome evolution and function.

Unraveling the role of satellite DNAs in the evolution of the giant XY sex chromosomes of the flea beetle Omophoita octoguttata (Coleoptera, Chrysomelidae)

BMC Biology
Background The flea beetle Omophoita octoguttata (Coleoptera, Chrysomelidae) is a member of a group in which the males completely lack meiotic recombination (male-specific achiasmy) and that have extraordinarily large X and Y chromosomes.

Enhancer activation from transposable elements in extrachromosomal DNA

Nature Cell Biology
Abstract Extrachromosomal DNA (ecDNA) drives oncogene amplification and intratumoral heterogeneity in aggressive cancers. While transposable element (TE) reactivation is common in cancer, its role on ecDNA remains unexplored.

Characterization of Transposable Elements in Pangenomes

, 2022
International audienceTransposable elements (TEs) are mobile DNA elements that can invade the genomes by transposition. Despite their reputation as parasitic sequences, these elements can enrich the genomes with functional novelties that foster genome ...
