Transcription of satellite DNAs in insects [PDF]
, 2011 Chromatin condensation is an important regulatory mechanism of gene silencing as well as gene activation for the hundreds of functional protein genes harbored in heterochromatic regions of different insect species.

Satellite DNA in Neotropical Deer Species [PDF]
Genes, 2021 The taxonomy and phylogenetics of Neotropical deer have been mostly based on morphological criteria and needs a critical revision on the basis of new molecular and cytogenetic markers. In this study, we used the variation in the sequence, copy number, and chromosome localization of satellite I-IV DNA to evaluate evolutionary relationships among eight ...

Uncoupling of satellite DNA and centromeric function in the genus Equus. [PDF]
PLoS Genetics, 2010 In a previous study, we showed that centromere repositioning, that is the shift along the chromosome of the centromeric function without DNA sequence rearrangement, has occurred frequently during the evolution of the genus Equus.

A species-specific satellite DNA family in the genome of the coffee root-knot nematode Meloidogyne exigua : Application to molecular diagnostics of the parasite [PDF]
, 2002 A new Bg/II satellite DNA has been isolated, cloned and sequenced from the coffee root-knot nematode, Meloidogyne exigua (Nematoda: Tylenchida). It is represented as tandemly repeated sequences with a monomeric unit of 277 bp. The monomers are present at

Scientific Reports, 2022 Amphibians have some of the most variable genome sizes among vertebrates. Genome size variation has been attributed to repetitive and noncoding DNA, including satellite repeats, transposable elements, introns, and nuclear insertions of viral and ...

Rapid generation of chromosome-specific alphoid DNA probes using the polymerase chain reaction [PDF]
, 1992 Non-isotopic in situ hybridization of chromosome-specific alphoid DNA probes has become a potent tool in the study of numerical aberrations of specific human chromosomes at all stages of the cell cycle. In this paper, we describe approaches for the rapid

European Journal of Entomology, 2017 Satellite DNAs are the major repetitive DNA components in eukaryotic genomes. Although satellite DNA has long been called "parasite DNA" there is substantial evidence that it could be associated with some functions of chromosome biology. Ladybird beetles

Molecular analysis and genomic organization of major DNA satellites in banana (Musa spp.). [PDF]
PLoS ONE, 2013 Satellite DNA sequences consist of tandemly arranged repetitive units up to thousands nucleotides long in head-to-tail orientation. The evolutionary processes by which satellites arise and evolve include unequal crossing over, gene conversion ...

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

Intra-specific variability and unusual organization of the repetitive units in a satellite DNA from Rana dalmatina: molecular evidence of a new mechanism of DNA repair acting on satellite DNA. [PDF]
, 2006 We have characterized the S1 satellite from eight European populations of Rana dalmatina by Southern blot, cloning and a new method that determines the sequence variability of repetitive units in the genome.
