Comparative cytogenetics of cichlid fishes through genomic in-situ hybridization (GISH) with emphasis on Oreochromis niloticus
(Chromosome Research, 2009-08-01) [Artigo]
Cichlidae is the most species-rich freshwater family of Perciformes and has attracted the attention of aquarium hobbyists, aquaculturists, and sport fisherman. Oreochromis niloticus is very important in aquaculture today ...
Classical and molecular cytogenetic characterization of Agonostomus monticola, a primitive species of Mugilidae (Mugiliformes)
(Genetica, 2009-01-01) [Artigo]
This study reports the first description of the karyotype of Agonostomus monticola, a species belonging to a genus which is considered to be the most primitive among living mugilid fish. Specimens from Panama and Venezuela ...
Genomic organization of repetitive DNAs in the cichlid fish Astronotus ocellatus
(Genetica, 2009-07-01) [Artigo]
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 ...
Molecular organization of 5S rDNA in sharks of the genus Rhizoprionodon: insights into the evolutionary dynamics of 5S rDNA in vertebrate genomes
(Genetics Research, 2009-02-01) [Artigo]
In this Study, we attempted a molecular characterization of the 5S rDNA in two closely related species of carcharhiniform sharks, Rhizoprionodon lalandii and Rhizoprionodon porosus, as well as a further comparative analysis ...
Genetic identification of the sharks Rhizoprionodon porosus and R. lalandii by PCR-RFLP and nucleotide sequence analyses of 5S rDNA
(Conservation Genetics Resources, 2009-12-01) [Artigo]
A molecular approach based on nuclear 5S rDNA sequence variability was applied successfully to correctly identify samples from the two Rhizoprionodon species collected in the wild or sold in markets. The sequence of the ...
Comparative chromosome mapping of repetitive sequences. Implications for genomic evolution in the fish, Hoplias malabaricus
(BMC Genetics, 2009-07-07) [Artigo]
Background: Seven karyomorphs of the fish, Hoplias malabaricus (A-G) were previously included in two major groups, Group I (A, B, C, D) and Group II (E, F, G), based on their similar karyotype structure. In this paper, ...
