Genomic differentiation of Deschampsia antarctica and D. cespitosa (Poaceae) based on satellite DNA
(Wiley Blackwell Publishing, Inc, 2020-07-04)
Repetitive DNA is a rapidly evolving component of vascular plant genomes, which can account for genomic differentiation in plant lineages. Satellite DNA (satDNA) is tandem repetitive DNA for which array size and disposition ...
Origin of B chromosomes in the genus Astyanax (Characiformes, Characidae) and the limits of chromosome painting
(Springer, 2016-06-01)
Eukaryote genomes are frequently burdened with the presence of supernumerary (B) chromosomes. Their origin is frequently investigated by chromosome painting, under the hypothesis that sharing the repetitive DNA sequences ...
Satellite DNA and chromosomal evolution in Ctenomys rodents: a necessary clarification
(Karger, 2011-05)
Ctenomys is a quite large group of South American subterranean rodents (more than 60 species) that exhibits the widest range of karyotype diversity in mammals with chromosomal diploid numbers (2n) ranging from 10 to 70. ...
Molecular and cytogenetic characterization of an AT-rich satellite DNA family in Urvillea chacoensis Hunz. (Paullinieae, Sapindaceae)
(Springer, 2009-12)
Urvillea chacoensis is a climber with 2n = 22 and some terminal AT-rich heterochromatin blocks that differentiate it from other species of the genus. The AT-rich highly repeated satellite DNA was isolated from U. chacoensis ...
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 ...
