“…There are several reports in marine species showing the co-location of NORs and heterochromatin (Galetti Jr. et al, 2000;Affonso and Galetti Jr., 2005;Molina and Bacurau, 2006;Sena and Molina, 2007;among others), similar to what was observed in the karyotype of the species analyzed herein (M. americanus, O. punctatissimus, P. acuminatus, and A. probatocephalus).…”

“…Several reports have demonstrated that the degree of karyotypic differentiation (number of changes in FN values) in some families of marine reef Perciformes (i.e., Pomacentridae; Labridae) is inversely related to the dispersive potential provided by the extent of pelagic larval duration of each species (Molina and Galetti Jr., 2004;Molina, 2006;Sena and Molina, 2007).…”

ABSTRACT.Fishes from the families Sciaenidae and Sparidae, the former comprising coastal species associated with shallow waters on the continental shelf and the latter composed of typically marine species, are of significant economic value. Karyotypic data are available for about 20% of the total number of species in these groups. In the present study, cytogenetic analyses were carried out in three Sciaenidae species, Menticirrhus americanus, Ophioscion punctatissimus and Pareques acuminatus, as well as in the sparid fish, Archosargus probatocephalus, using conventional staining (Giemsa) and Ag-nucleolar organizer regions (NORs) and C-banding techniques. The diploid values (2n) and number of chromosome arms were equal to 48 in all species analyzed. NORs were located at pericentromeric positions, equivalent to large heterochromatic blocks, in M. americanus (1st pair), O. punctatissimus (10th pair), P. acuminatus (2nd pair), and A. probatocephalus (3rd pair). Heterochromatin was detected at the centromeric position in most chromosome pairs, being more conspicuous among Scianidae members. The remarkable karyotypic conservativeness detected in these species is similar to that observed in other perciform groups previously studied, regarding both the number of acrocentric chromosomes and NOR location. However, unusual events of heterochromatinization seem to have taken place along the karyotypic evolution of members of the family Sciaenidae. For the family Sparidae, distinct cytotypes between samples of Northeast Brazil and those previously analyzed on the southeastern coast were identified, suggesting that putative biogeographic barriers Cytogenetic studies in Sciaenidae and Sparidae fishes could be present throughout both regions on South Atlantic coast.

Standardized Karyotype and Idiogram of Quoy's Parrotfish, Scarus quoyi (Perciformes: Scaridae) by Conventional Staining and Ag-NOR Banding Techniques

et al. 2014

Summary This is the first report on standardized karyotype and idiogram analyses of Quoy s parrotfish, Scarus quoyi, from the Andaman Sea, Southern Thailand. Kidney cell samples were taken from three male and three female fish. Mitotic chromosome preparations were prepared directly from kidney cells. Conventional staining and Ag-NOR banding techniques were applied to stain the chromosomes. The results showed that the diploid chromosome number of Sc. quoyi was 2n=48, and the fundamental number (NF) was 74 in both males and females. The types of chromosomes were 4 large metacentric, 4 large submetacentric, 16 large acrocentric, 18 large telocentric, 2 medium acrocentric, 2 medium telocentric, and 2 small telocentric chromosomes. There were no irregularly sized chromosomes related to sex. The region adjacent to the short arm near the telomere of acrocentric chromosome pair 6 showed clearly observable nucleolar organizer regions/NORs.

“…This approach has been routinely tested on an array of fish species from several orders such as Perciformes (Sena and Molina, 2007), Anguilliformes (Vasconcelos and Molina, 2009), Beryciformes (Bacurau and Molina, 2004), and Characiformes (Medrado et al, 2008;Pamponet et al, 2008), among others.…”
