ZZ/Z0: The New System of Sex Chromosomes in Eigenmannia aff. trilineata (Teleostei: Gymnotiformes: Sternopygidae) Characterized by Molecular Cytogenetics and DNA Barcoding
(Mary Ann Liebert, Inc, 2017-10-01)
The cytogenetic characteristics of Eigenmannia aff. trilineata were analyzed by basic and molecular cytogenetics, applying fluorescent in situ hybridization, with 18S and 5S rDNA and U2 snRNA probes. The species revealed ...
Chromosomal evolutionary dynamics of four multigene families in Coreidae and Pentatomidae (Heteroptera) true bugs
(2016-10-01)
Previous chromosome mapping of multigene families in Pentatomomorpha (Heteroptera) insects, which was restricted to the major rDNA, revealed remarkable conservation of number of clusters and chromosomal positions. Aiming ...
Karyotypic conservatism in samples of Characidium cf. zebra (Teleostei, Characiformes, Crenuchidae): physical mapping of ribosomal genes and natural triploidy
(Sociedade Brasileira de Genética, 2011-01-01)
Basic and molecular cytogenetic analyses were performed in specimens of Characidium cf. zebra from five collection sites located throughout the Tietê, Paranapanema and Paraguay river basins. The diploid number in specimens ...

Cytogenetic and molecular markers reveal the complexity of the genus Piabina Reinhardt, 1867 (Characiformes: Characidae)
(Sociedade Brasileira de Ictiologia, 2012-01-01)
Foram realizadas análises citogenéticas e moleculares em representantes do gênero Piabina. O estudo envolveu especificamente as espécies P. argentea e P. anhembi coletadas nas áreas das bacias hidrográficas dos rios ...
25S–18S rDNA IGS of Capsicum: molecular structure and comparison
(Springer, 2012-02)
The primary and secondary structures of the intergenic spacer (IGS) between the 3′-end of 25S ribosomal RNA (rRNA) gene and the 5′-end of 18S rRNA gene are described for the cultivated chili pepper Capsicum pubescens. The ...
