Nucleotide sequence of 5S rDNA and localization of the ribosomal RNA genes to metaphase chromosomes of the Tilapiine cichlid fish, Oreochromis niloticus
(2000-12-01)
In this study, we report the cloning and nucleotide sequence of PCR-generated 5S rDNA from the Tilapiine cichlid fish, Oreochromis niloticus. Two types of 5S rDNA were detected that differed by insertions and/or deletions ...
Sequence heterogeneity and phylogenetic relationships between the copia retrotransposon in Drosophila species of the repleta and melanogaster groups
(Edp Sciences S A, 2006-09-01)
Although the retrotransposon copia has been studied in the melanogaster group of Drosophila species, very little is known about copia dynamism and evolution in other groups. We analyzed the occurrence and heterogeneity of ...
Complete nucleotide sequence of a new begomovirus infecting a malvaceous weed in Brazil

Completion of the Nucleotide Sequence of a Brazilian Isolate of Southern bean mosaic virus
(Wiley-Blackwell Publishing, Inc, 2009-09-01)
The sequence of the central part (ORF2) of a Brazilian isolate of Southern bean mosaic virus (SBMV(SP)) is described. This ORF is 2888 nt long and together with the previously-sequenced 5' and 3' ends provides the complete ...
Effects of a single nucleotide polymorphism in the leptin gene on the productive traits of dairy buffaloes (Bubalus bubalis)
(2013-08-01)
The gene responsible for coding the leptin hormone has been associated with productive and reproductive traits in cattle. In dairy cattle, different polymorphisms found in the leptin gene have been associated with several ...
Araçatuba virus: A vaccinialike virus associated with infection in humans and cattle
(2003-02-01)
We describe a vaccinialike virus, Araçatuba virus, associated with a cowpoxlike outbreak in a dairy herd and a related case of human infection. Diagnosis was based on virus growth characteristics, electron microscopy, and ...
Nucleotide sequence, genomic organization and chromosome localization of 5S rDNA in two species of Curimatidae (Teleostei, Characiformes)
(Sociedade Brasileira de Genética, 2006-01-01)
The 5S ribosomal DNA (5S rDNA) of higher eukaryotes is organized in repeat units of tandem arrays composed of a 5S rDNA coding region, conserved even among non-related taxa, and a variable non-transcribed spacer sequence ...
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) ...
Characterization of eight single nucleotide polymorphism markers in Aedes aegypti
(Wiley-Blackwell Publishing, Inc, 2009-01-01)
Sequencing of part of seven genes from Aedes aegypti collected in 16 Brazilian cities revealed the existence of 53 single nucleotide polymorphisms (SNPs), representing one SNP every 52 base pairs. From these 53 SNPs, we ...
