Chromosomal organization of repetitive DNA sequences in Astyanax bockmanni (Teleostei, Characiformes): dispersive location, association and co-localization in the genome
(2013-09-06)
Repetitive DNA sequences constitute a great portion of the genome of eukaryotes and are considered key components to comprehend evolutionary mechanisms and karyotypic differentiation. Aiming to contribute to the knowledge ...
Karyotype and nucleolus organizer regions of ophisternon aenigmaticum (teleostei: Synbranchiformes: Synbranchidae) from venezuela (in english)
(2011-03-01)
The first cytogenetic analysis by conventional Giemsa staining, silver nitrate impregnation of nucleolus organizer regions (Ag-NOR), and fluorescence in situ hybridization (FISH) carried out on Ophisternon aenigmaticum ...
Satellite DNA Derived from 5S rDNA in Physalaemus cuvieri (Anura, Leiuperidae)
(KargerBaselSuíça, 2011)
Taxonomic and phylogenetic relationships between neotropical species of ticks from genus Amblyomma (Acari: Ixodidae) inferred from second internal transcribed spacer sequences of rDNA
(2007-03-01)
The accurate specific identification of ticks is essential for the study, control and prevention of tick-borne diseases. Herein, we determined ribosomal nucleotide sequences of the second internal transcribed spacer (ITS2) ...
Location of 45S Ribosomal Genes in Mitotic and Meiotic Chromosomes of Buthid Scorpions
(Zoological Soc Japan, 2014-09-01)
Buthid scorpions exhibit a high variability in diploid number within genera and even within species. Cytogenetically, Buthidae differs from other families of Scorpiones based on its low diploid numbers, holocentric ...
Chromosomal differentiation of Tribe Cestreae (Solanaceae) by analyses of 18-5.8-26S and 5S rDNA distribution
(Springer Wien, 2014-10)
Tribe Cestreae is monophyletic with three genera: Cestrum, Sessea, and Vestia. Karyotypically, it is outstanding within Solanaceae by several features: (1) basic number x = 8, (2) large chromosome sizes, (3) complex ...
