Analysis of repeat elements in the Pristionchus pacificus genome reveals an ancient invasion by horizontally transferred transposons

BMC Genomics, 2022
Background Repetitive sequences and mobile elements make up considerable fractions of individual genomes. While transposition events can be detrimental for organismal fitness, repetitive sequences form an enormous reservoir for molecular innovation.

Normalization of genomic DNA using duplex-specific nuclease

BioTechniques, 2010
An application of duplex-specific nuclease (DSN) normalization technology to whole-genome shotgun sequencing of genomes with a large proportion of repetitive DNA is described.

Epigenetics and triplet repeat neurological diseases

Frontiers in Neurology, 2015
The term ‘junk DNA’ has been reconsidered following the delineation of the functional significance of repetitive DNA regions. Typically associated with centromeres and telomeres, DNA repeats are found in nearly all organisms throughout their genomes ...

Contrasting the Chromosomal Organization of Repetitive DNAs in Two Gryllidae Crickets with Highly Divergent Karyotypes. [PDF]

PLoS ONE, 2015
A large percentage of eukaryotic genomes consist of repetitive DNA that plays an important role in the organization, size and evolution. In the case of crickets, chromosomal variability has been found using classical cytogenetics, but almost no ...

Chromosomal Differentiation of Deschampsia (Poaceae) Based on Four Satellite DNA Families

Frontiers in Genetics, 2021
Diverse families of satellite DNA (satDNA) were detected in heterochromatin regions of Deschampsia. This kind of repetitive DNA consists of tandem repeat sequences forming big arrays in genomes, and can contribute to lineages differentiation.

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 ...

The genome organization of repetitive sequences in the Golden Damselfish, Amblyglyphidodon aureus (Cuvier, 1830) (Family Pomacentridae): insights from extensive pericentric inversions

Caryologia
The genus Amblyglyphidodon (damselfishes) is one of the most distinctive fish groups in the Indo-Pacific coral reef ecosystem. It consists of 11 recognized species, which display complex taxonomic relationships and cryptic lineages across their extensive

Nucleolar epigenomics by dynamic molecular combing and nucleolar matrix analysis [PDF]

, 2013
With the sequencing of the human genome essentially complete, a comprehensive view is now needed on how the genetic information is established in different cell types and developmental stages and how it is inherited through cell divisions.

A new repetitive DNA sequence from Trypanosoma cruzi

Memorias do Instituto Oswaldo Cruz, 1991
Tandemly repeated DNA sequences are found in the genome of higher eukaryotes, and have also been demonstrated in Trypanosoma cruzi. Repeated DNA sequences are potentially useful for the diagnostic detection of T. cruzi (A.
