Nucleotide sequence, genomic organization and chromosome localization of 5S rDNA in two species of Curimatidae (Teleostei, Characiformes)

Genetics and Molecular Biology, 2006
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 (NTS). To contribute to knowledge

Molecular Evolution and Organization of Ribosomal DNA in the Hawkweed Tribe Hieraciinae (Cichorieae, Asteraceae)

Frontiers in Plant Science, 2021
Molecular evolution of ribosomal DNA can be highly dynamic. Hundreds to thousands of copies in the genome are subject to concerted evolution, which homogenizes sequence variants to different degrees.

Sequences and evolutionary analysis of mouse 5S rDNAs. [PDF]

Molecular Biology and Evolution, 1994
We selectively amplified the spacer regions of genes for mouse 5S ribosomal RNA (rRNA), which are tandemly repeated, by the PCR method, using primers specific to the two ends of the coding region for 5S rRNA. Fragments of approximately 1.6 kb were amplified from DNA from the BALB/cCrSlc mouse (Mus musculus domesticus), the SM/J mouse (M. m. domesticus),

Regulation of Pol I-Transcribed 45S rDNA and Pol III-Transcribed 5S rDNA in Arabidopsis [PDF]

Plant and Cell Physiology, 2011
The 18S, 5.8S and 25S rRNAs, which result from the 45S precursor, together with 5S rRNAs, are central components of the ribosome. The integration of one molecule of each rRNA per ribosome necessitates an elaborate coordination between transcriptions of the two ribosomal DNA (rDNA) families.

5S rDNA characterization in twelve Sciaenidae fish species (Teleostei, Perciformes): depicting gene diversity and molecular markers

Genetics and Molecular Biology, 2008
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) analysis.

Chromosomal Locations of 5S and 45S rDNA in Gossypium Genus and Its Phylogenetic Implications Revealed by FISH. [PDF]

PLoS ONE, 2013
We investigated the locations of 5S and 45S rDNA in Gossypium diploid A, B, D, E, F, G genomes and tetraploid genome (AD) using multi-probe fluorescent in situ hybridization (FISH) for evolution analysis in Gossypium genus.

Molecular Organization and Chromosomal Localization Analysis of 5S rDNA Clusters in Autotetraploids Derived From Carassius auratus Red Var. (♀) × Megalobrama amblycephala (♂)

Frontiers in Genetics, 2019
The autotetraploid fish (4n = 200, RRRR) (abbreviated as 4nRR) resulted from the whole genome duplication of red crucian carp (Carassius auratus red var., 2n = 100, RR) (abbreviated as RCC).

Characterisation of 5S rDNA inGasterosteus aculeatus(Teleostei, Gasterosteidae) [PDF]

Italian Journal of Zoology, 1999
Abstract The 5S rRNA genes of Gasterosteus aculeatus were characterised. Genomic DNA was amplified by PCR using two primers constructed in different salmonid species in order both to extract the total 5S rDNA (coding region + nontranscribed spacer region) and to generate amplified DNA products only if 5S rDNAs were tandemly arrayed.

Cytogenetic Analysis of Altitude-Associated Chromosome Variations in <i>Campeiostachys nutans</i> From Western Sichuan Plateau Using Multicolor GISH and ND-FISH Approaches. [PDF]

Ecol Evol
The genomic and chromosomal organization of C. nutans was investigated using GISH and ND‐FISH with four oligonucleotide probes. The results showed that repetitive sequence distribution exhibited genome‐specific patterns: the H genome demonstrated high structural stability with low polymorphism, while the St genome showed moderate variation, and the Y ...

Molecular organization of 5S rDNA in sharks of the genusRhizoprionodon: insights into the evolutionary dynamics of 5S rDNA in vertebrate genomes

Genetics Research, 2009
SummaryIn this study, we attempted a molecular characterization of the 5S rDNA in two closely related species of carcharhiniform sharks,Rhizoprionodon lalandiiandRhizoprionodon porosus, as well as a further comparative analysis of available data on lampreys, several fish groups and other vertebrates.
