Forensic identification of the guitarfish species Rhinobatos horkelli, R-percellens and Zapteryx brevirostris using multiplex-PCR
(Molecular Ecology Resources, 2010-01-01) [Resumo]
Rhinobatos percellens, Rhinobatos horkelli and Zapteryx brevirostris, known as guitarfish, are commonly found inshore and caught by trawl nets. Recently, these species have been suffering sharp population declines. One of ...
Identification of the shark species Rhizoprionodon lalandii and R-porosus (Elasmobranchii, Carcharhinidae) by multiplex PCR and PCR-RFLP techniques
(Molecular Ecology Resources, 2009-05-01) [Artigo]
Rhizoprionodon lalandii and R. porosus are widely distributed along the Atlantic coast of the Americas, living close to coastal areas and therefore frequently captured by seaboard fisheries. However, morphological ...
Delimiting the Origin of a B Chromosome by FISH Mapping, Chromosome Painting and DNA Sequence Analysis in Astyanax paranae (Teleostei, Characiformes)
(PLOS ONE, 2014-04-15) [Artigo]
Supernumerary (B) chromosomes have been shown to contain a wide variety of repetitive sequences. For this reason, fluorescent in situ hybridisation (FISH) is a useful tool for ascertaining the origin of these genomic ...
Isolation and characterization of microsatellite loci in the Neotropical fish Astyanax altiparanae (Teleostei: Characiformes) and cross-species amplification
(Journal of Genetics, 2012-04-01) [Artigo]
Common Descent of B Chromosomes in Two Species of the Fish Genus Prochilodus (Characiformes, Prochilodontidae)
(Cytogenetic and Genome Research, 2013-01-01) [Artigo]
To ascertain the origin of B chromosomes in 2 fish species of the genus Prochilodus, i.e. P. lineatus and P. nigricans, we microdissected them and generated B-specific DNA probes. These probes were used to perform chromosome ...
Karyotypic conservatism in five species of Prochilodus (Characiformes, Prochilodontidae) disclosed by cytogenetic markers
(Genetics and Molecular Biology, 2013-09-05) [Artigo]
The family Prochilodontidae is considered a group with well conserved chromosomes characterized by their number, morphology and banding patterns. Thence, our study aimed at accomplishing a cytogenetic analysis with ...
