Cytogenetic characterization of Rhomboplites aurorubens and Ocyurus chrysurus, two monotypic genera of Lutjaninae from Cubagua Island, Venezuela, with a review of the cytogenetics of Lutjanidae (Teleostei: Perciformes)

Abstract: Lutjanidae, commonly known as snappers, includes 105 species, grouped in four subfamilies. In spite of the high number of species and of its worldwide distribution, the family has been little investigated and the phylogenetic relationships among some of its genera and species are still cause for debate. Only a small number of the species has been cytogenetically analysed. This study reports the first description of the karyotype of Rhomboplites aurorubens as well as data concerning the distribution of the cons… Show more

“…Species known or suspected of hybridization with Ocyurus now include L. synagris and L. griseus (Domeier & Clarke (1992), L. jocu (Bortone & Williams, 1986), and L. apodus and L. analis (Carson & Gold, unpubl.). Placement of Ocyurus into Lutjanus also is consistent with, although not necessarily strongly supported by, the mtDNA phylogenies generated by Sarver et al (1996) and Rodríguez-Santiago (2008), and with the cytogenetic studies of Nirchio et al (2009). To our knowledge, no one has questioned whether Rhomboplites also should be included in Lutjanus, although inclusion of Rhomboplites within Lutjanus was reflected in, but not strongly supported by, the studies of Sarver et al (1996) and Rodríguez-Santiago (2008).…”

“…However, evidence of colocalization of 5S and 18S rDNA has been reported for some species of Acipenseriformes (Fontana et al, 2003), Salmoniformes (e.g., Pendas et al, 1994;Moran et al, 1996;Fujiwara et al, 1998;Rossi & Gornung, 2005), Cypriniformes (Inafuku et al, 2000), Characiformes (e.g., Almeida-Toledo et al, 2002;Cioffi et al, 2009;Diniz et al, 2009 and references therein), Perciformes (Nirchio et al, 2009;Pisano & Ghigliotti, 2009) and, now also, Mugiliformes (present study). Interestingly, all the possible syntenic conditions have been found, either the two sets of genes in distinct and disjoint chromosomal regions, as in Astyanax scabripinnis (Mantovani et al, 2005) and Parodon tortuosus (=Parodon nasus) (Vicente et al, 2001), or in adjacent regions, as in M. incilis (present study) and Triportheus nematurus (Diniz et al, 2009), or the 5S rRNA genes interspersed along the clusters of 45S rDNA, as in Notothenioidei (Pisano & Ghigliotti, 2009).…”

“…The presence of clusters of these sequences either very close to or far apart from each other on the same chromosome has already been reported in teleosts including Salmo salar (Pendás et al, 1994), Oncorhynchus mykiss (Morán et al, 1996), Acheilognathus tabira subsp. 1, Cyprinus carpio (Inafuku et al, 2000), Rhomboplites aurorubens (Nirchio et al, 2009) and Mugil incilis (Hett et al, 2011). Although the terminal localization of single major ribosomal genes on the short arm of a pair of chromosomes seems to be a shared feature among the species of lionfish cytogenetically studied until now (Caputo et al, 2003;this paper), reports on co-localization of 18S and 5S ribosomal genes in P. volitans, as revealed by the multi-colour FISH are restricted to this study.…”
