Abstract: This study reports the description of the karyotype of Mugil incilis from Venezuela. The chromosome complement is composed of 48 acrocentric chromosomes, which uniformly decrease in size. Therefore, the homologues can not be clearly identified, with the exception of one of the largest chromosome pairs, classified as number 1, whose homologues may show a subcentromeric secondary constriction, and of chromosome pair number 24, which is considerably smaller than the others. C-banding showed heterochromatic blocks… Show more

“…At each node, bootstrap values > 70% (NJ and ML) and posterior probabilities > 0.9 (BI) are shown. Stars indicate sequences obtained in this study; the remaining sequences are from Durand et al (2012), Durand and Borsa (2015) and from Hett et al (2011) (see Table 1). For each lineage, the karyotype (2n), the fundamental number (FN) and the chromosome formula are indicated.…”

“…It is worth noting that in the phylogenetic trees, the node separating “ M. curema ” lineages from Mugil incilis was not resolved (Fig. 4, Durand et al 2012, Durand and Borsa 2015), and the latter species shows a karyotype (Hett et al 2011) that is the closest to the “typical” all uniarmed mullet karyotype from which, presumably, the “ M. curema ” Robertsonian karyotypes derived. In a very recent paper (Xia et al 2016) based both on molecular and diagnostic morphological characters, M. incilis appears to be the sister species to “ Mugil curema ” lineages, and M. thoburni is external to them.…”

“…This may explain why most vertebrates have these sequences on different chromosomes. Interestingly, all the possible syntenic conditions have been found in fishes, both sets of genes in distinct and disjoint chromosomal regions, as observed in Parodon nasus Kner, 1859 cited as Parodon tortuosus (Vicente et al 2001) and Astyanax paranae Eigenmann, 1914 cited as Astyanax scabripinnis (Mantovani et al 2005), or in adjacent regions, as in Triportheus nematurus (Kner, 1858) (Diniz et al 2009), Mugil incilis Hancock, 1830 (Hett et al 2011), Kronichthys lacerta , Isbrueckerichthys duseni , Parotocinclus maculicauda , Trichomycterus sp. (Ziemniczak et al 2012) and Callichthys callichthys (Konerat et al 2014), or the 5S rDNA interspersed along the clusters of 45S rDNA (co-localization), as in Astyanax altiparanae Garutti & Britski, 2000, Astyanax lacustris (Lütken, 1875), Astyanax fasciatus (Cuvier, 1819), Astyanax schubarti Britski, 1964 and Astyanax paranae cited as Astyanax scabripinnis (Almeida-Toledo et al 2002), Solea senegalensis Kaup, 1858 (Cross et al 2006), Bryconamericus cf.…”

“…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.…”
