Ortholog of the polymerase theta helicase domain modulates DNA replication in Trypanosoma cruzi
(Nature Research, 2019)
How dynamic could be the 45S rDNA cistron? An intriguing variability in a grasshopper species revealed by integration of chromosomal and genomic data
(2019-06-04)
To better understand the structure and variability of the 45S rDNA cistron and its evolutionary dynamics in grasshoppers, we performed a detailed analysis combining classical and molecular cytogenetic data with whole-genome ...
Localization of ribosomal genes in three Pimelodus species (Siluriformes, Pimelodidae) of the São Francisco River: 5S genes as species markers and conservation of the 18S rDNA sites
(Sociedade Brasileira de Genética, 2008)
Pimelodidae is one of the most representative of Neotropical catfish families. However, these fish are still poorly studied in terms of cytogenetics, especially regarding the application of more accurate techniques such ...
Chromosomal Variability among Allopatric Populations of Erythrinidae Fish Hoplias malabaricus: Mapping of Three Classes of Repetitive DNAs
(Karger, 2009-01-01)
Karyotype and chromosomal characteristics from 3 allopatric populations of Hoplias malabaricus, cytogenetically the most studied Erythrinidae taxon, were investigated using different staining techniques (C-, Ag-, and CMA(3) ...

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 ...
5S rDNA characterization in twelve Sciaenidae fish species (Teleostei, Perciformes): depicting gene diversity and molecular markers
(Sociedade Brasileira de Genética, 2008-01-01)
In order to extend the genetic data on the Sciaenidae fish family, the present study had the purpose to characterize PCR-generated 5S rDNA repeats of twelve species of this group through PAGE (Polyacrylamide Gel Electrophoresis) ...
