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 ...
A Glimpse into the Satellite DNA Library in Characidae Fish (Teleostei, Characiformes)
(Frontiers Media Sa, 2017-08-14)
Satellite DNA (satDNA) is an abundant fraction of repetitive DNA in eukaryotic genomes and plays an important role in genome organization and evolution. In general, satDNA sequences follow a concerted evolutionary pattern ...
Origin and differentiation of a sex chromosome system in Parodon hilarii (Pisces, Parodontidae). Satellite DNA, G- and C-banding
(Kluwer Academic Publ, 2003-10-01)
A satellite DNA sequence of Parodon hilarii ( named pPh2004) was isolated, cloned and sequenced. This satellite DNA is composed of 200 bp, 60% AT rich. In situ hybridization ( FISH) results revealed that the satellite DNA ...
Genomic organization and transcription analysis of the 195-bp satellite DNA in Trypanosoma cruzi
(ELSEVIER SCIENCE BV, 2008)
The 195-bp satellite DNA is the most abundant Trypanosoma cruzi repetitive sequence. Here we show by RNA blotting and RT-PCR that 195 SAT is intensely transcribed. We observed a positive correlation between the level of ...
Isolation and characterization of a satellite DNA family in Achirus lineatus (Teleostei : Pleuronectiformes : Achiridae)
(Springer, 2005-11-01)
Agarose gels stained with Ethidium bromide and Southern blot experiments of HindIII-digested genomic DNA of Achirus lineatus evidenced the presence of monomers and multimers of a DNA segment of about 200 bp, named here ...
Molecular characterization and chromosomal localization of two families of satellite DNA in Prochilodus lineatus (Pisces, Prochilodontidae), a species with B chromosomes
(2003-05-01)
Prochilodus lineatus, an abundant species in the Mogi-Guaçu river basin, represents a large part of the region's fishing potential. Karyotypic analyses based on classic cytogenetic techniques have revealed the presence of ...
Low Satellite DNA Variability in Natural Populations of Drosophila antonietae Involved in Different Evolutionary Events
(OXFORD UNIV PRESS INC, 2010)
Drosophila antonietae is a cactophilic species that is found in the mesophilic forest of the Parana`-Paraguay river basin and in the dunes of the South Atlantic coast of Brazil. Although the genetic structure of the ...
A tandemly repetitive centromeric DNA sequence of the fish Hoplias malabaricus (Characiformes : Erythrinidae) is derived from 5S rDNA
(Springer, 2006-05-01)
A substantial fraction of the eukaryotic genome consists of repetitive DNA sequences that include satellites, minisatellites, microsatellites, and transposable elements. Although extensively studied for the past three ...
