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 ...
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 ...
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 ...

Nucleotide sequence differentiation of argentine isolates of the mosquito parasitic nematode Strelkovimermis spiculatus (Nematode: Mermithidae)
(Soc Vector Ecology, 2015-12)
Strelkovimermis spiculatus is an obligate parasite of mosquito larvae that breeds in environments of permanent flooding or in habitats subjected to periods of desiccation. Differences in epizootic levels within these ...
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 ...
