Tracking the evolution of sex chromosome systems in Melanoplinae grasshoppers through chromosomal mapping of repetitive DNA sequences
(BioMed Central, 2013-08)
Background: The accumulation of repetitive DNA during sex chromosome differentiation is a common feature of many eukaryotes and becomes more evident after recombination has been restricted or abolished. The accumulated ...
Human repetitive and unique sequences coexist in a large circulating DNA species found in cryoprecipitates from SLE patients
(Clinical & Experimental Immunology, 2017)
Genomic organization of repetitive DNAs in the cichlid fish Astronotus ocellatus
(Springer, 2009-07-01)
To contribute to the knowledge of fish genomes, we identified and characterized by means of nucleotide sequencing and physical chromosome mapping, three classes of repetitive DNAs in the genome of the South American cichlid ...

Chromosomal Mapping of Repetitive DNA Sequences in the Genus Bryconamericus (Characidae) and DNA Barcoding to Differentiate Populations
(Mary Ann Liebert, Inc, 2017-06-01)
The mapping of repetitive DNA sites by fluorescence in situ hybridization has been widely used for karyotype studies in different species of fish, especially when dealing with related species or even genera presenting high ...
U1 snDNA chromosomal mapping in ten spittlebug species (Cercopidade, Auchenorrhyncha, Hemiptera)
(Canadian Science Publishing, Nrc Research Press, 2018-01-01)
Spittlebugs, which belong to the family Cercopidae (Auchenorrhyncha, Hemiptera), form a large group of xylemfeeding insects that are best known for causing damage to plantations and pasture grasses. The holocentric chromosomes ...
Molecular characterization of SSS139, a new satellite DNA family in sibling species of the Drosophila buzzatii cluster
(Sociedade Brasileira de Genética, 2008)
We characterized sequences of a novel SSS139 RsaI satellite DNA family in Drosophila gouveai and Drosophila seriema, two members of the Drosophila buzzatii cluster (D. repleta group). The sequences were AT-rich (69%) with ...
Conserved number of U2 snDNA sites in Piabina argentea, Piabarchus stramineus and two Bryconamericus species (Characidae, Stevardiinae)
(2018-01-01)
The chromosomal location of 5S rRNA and U2 snRNA genes of Piabina argentea, Piabarchus stramineus and two Bryconamericus species from two different Brazilian river basins were investigated, in order to contribute to the ...
The tritryps comparative repeatome: insights on repetitive element evolution in trypanosomatid pathogens
(Society for Molecular Biology and Evolution, 2019)
The major human pathogens Trypanosoma cruzi, Trypanosoma brucei, and Leishmania major are collectively known as the Tritryps. The initial comparative analysis of their genomes has uncovered that Tritryps share a great ...
