Evolutionary Dynamics of Satellite DNA Repeats across the Tettigoniidae Family: Insights from Genomic Analysis [PDF]

open access: yesBiomolecules
Satellite DNA repeats are repetitive DNA sequences found in eukaryotic genomes, typically consisting of short DNA motifs repeated in tandem arrays. Despite the vast body of literature on satellite DNA repeats in other taxa, investigations specifically ...

Antibiotics induce overexpression of alpha satellite DNA accompanied with epigenetic changes at alpha satellite arrays as well as genome-wide [PDF]

open access: yesEpigenetics & Chromatin
The transcription of satellite DNA is highly sensitive to environmental factors and represents a source of genomic instability. Therefore, tight regulation of (peri)centromeric transcription is essential for genome maintenance.

Multi-tissue characterization of the constitutive heterochromatin proteome in Drosophila identifies a link between satellite DNA organization and transposon repression. [PDF]

open access: yesPLoS Biology
Noncoding satellite DNA repeats are abundant at the pericentromeric heterochromatin of eukaryotic chromosomes. During interphase, sequence-specific DNA-binding proteins cluster these repeats from multiple chromosomes into nuclear foci known as ...

Topoisomerase I is an evolutionarily conserved key regulator for satellite DNA transcription [PDF]

open access: yesNature Communications
RNA Polymerase (RNAP) II transcription on non-coding repetitive satellite DNAs plays an important role in chromosome segregation, but a little is known about the regulation of satellite transcription.

Genome size and identification of repetitive DNA sequences using low coverage sequencing in Hancornia speciosa Gomes (Apocynaceae: Gentianales) [PDF]

open access: yesGenetics and Molecular Biology, 2020
Repetitive DNA is an important component of eukaryotic genomes, accounting for more than 90% of the genome size of some species, including mobile elements and satellite DNA sequences.

Test of the correlation between body size and DNA content in Pimelia (Coleoptera: Tenebrionidae) from the Canary Islands

open access: yesEuropean Journal of Entomology, 2003
Comparative analyses of interspecific data in evolutionary biology usually require specific methods to remove the effects of phylogenetic inertia. When phylogenetic inertia is not considered, the Canarian Pimelia species show a positive, and almost ...

GlaI digestion of mouse γ-satellite DNA: study of primary structure and ACGT sites methylation

open access: yesBMC Genomics, 2009
Background Patterns of mouse DNA hydrolysis with restriction enzymes are coincided with calculated diagrams of genomic DNA digestion in silico, except presence of additional bright bands, which correspond to monomer and dimer of γ-satellite DNA.

The modular mechanism of chromocenter formation in Drosophila

open access: yeseLife, 2019
A central principle underlying the ubiquity and abundance of pericentromeric satellite DNA repeats in eukaryotes has remained poorly understood. Previously we proposed that the interchromosomal clustering of satellite DNAs into nuclear structures known ...

Conservation of Major Satellite DNAs in Snake Heterochromatin

open access: yesAnimals, 2023
Repetitive DNA sequences constitute a sizeable portion of animal genomes, and tandemly organized satellite DNAs are a major part of them. They are usually located in constitutive heterochromatin clusters in or near the centromeres or telomeres, and less ...

Evaluation of intra- and interspecific divergence of satellite DNA sequences by nucleotide frequency calculation and pairwise sequence comparison

open access: yesBiological Procedures Online, 2003
Satellite DNA sequences are known to be highly variable and to have been subjected to concerted evolution that homogenizes member sequences within species.
