Chromosome mapping of repetitive sequences in Anostomidae species: Implications for genomic and sex chromosome evolution
(2012-12-01)
Background: Members of the Anostomidae family provide an interesting model system for the study of the influence of repetitive elements on genome composition, mainly because they possess numerous heterochromatic segments ...

Dynamics and cytochemistry of oogenesis in Leporinus striatus Kner (Teleostei, Characiformes, Anostomidae) from the Rio Sapucaí, Minas Gerais State, Brazil
(Sociedade Brasileira de Zoologia, 2001-12-01)
Oogenesis involves a sequense of transformations which are undergone by female germ cells. These cells change into oogonias and then into mature oocytes. Sexually mature females were collected monthly, during one year, ...

HETEROCHROMATIN AND KARYOTYPE REORGANIZATION IN FISH OF THE FAMILY ANOSTOMIDAE (CHARACIFORMES)
(Karger, 1991-01-01)
Mitotic chromosomes of four fish species of the family Anostomidae, belonging to the genera Leporinus, Leporellus, and Schizodon, were studied. With 2n = 54 meta- and submetacentric chromosomes, this family appears to be ...

5S rDNA variation and its phylogenetic inference in the genus Leporinus (Characiformes : Anostomidae)
(Springer, 2007-03-01)
5S rDNA sequences have proven to be valuable as genetic markers to distinguish closely related species and also in the understanding of the dynamic of repetitive sequences in the genomes. In the aim to contribute to the ...
Chromosomal locations of U2 snDNA clusters in Megaleporinus, Leporinus and Schizodon (Characiformes: Anostomidae)
(2018-03-01)
The U small nuclear RNA (U snRNA) genes comprise a multigene family and are required for splicing of pre-mRNA. In this paper, we aimed to study the chromosomal location of the U2 snRNA gene in Megaleporinus, Leporinus and ...
