Expression of yeast 5S RNA is independent of the rDNA enhancer region [PDF]

open access: yesNucleic Acids Research, 1990
In the yeast Saccharomyces cerevisiae, each of the tandemly repeated ribosomal RNA genes carries a 5S gene within the 'non-transcribed' spacer region. These 5S RNA genes lie between the rDNA enhancer and the promoter of rRNA transcription. Since there is roughly equimolar synthesis of 5S RNA and the 35S rRNA precursor transcript we asked whether the ...

Heterochromatin diversity and its co-localization with 5S and 45S rDNA sites in chromosomes of four Maxillaria species (Orchidaceae)

open access: yesGenetics and Molecular Biology, 2006
We investigated four orchids of the genus Maxillaria (M. discolor, M. acicularis, M. notylioglossa and M. desvauxiana) in regard to the position of heterochromatin blocks as revealed using chromomycin A3 (CMA) and 4'-6-diamidino-2-phenylindole (DAPI ...

Molecular organization and chromosomal localization of 5S rDNA in Amazonian Engystomops (Anura, Leiuperidae)

open access: yesBMC Genetics, 2012
Background For anurans, knowledge of 5S rDNA is scarce. For Engystomops species, chromosomal homeologies are difficult to recognize due to the high level of inter- and intraspecific cytogenetic variation. In an attempt to better compare the karyotypes of

Evolutionary relationship of three mitten crabs (Eriocheir sp) revealed by mitogenome and 5S ribosomal DNA analysis

open access: yesAquaculture and Fisheries, 2017
To reveal the evolutionary relationship of three mitten crabs (Eriocheir sinensis, E. hepuensis, and E. japonica), complete mitogenomes and nuclear 5S rDNA sequences were analyzed.

Karyological and nuclear DNA content variation of the genus Asparagus.

open access: yesPLoS ONE, 2022
Asparagus wild relatives could be a promising possibility to extent the genetic variability of garden asparagus and for new cultivars with favorable traits such as high yield stability, disease resistance and stress tolerance.

Mapping of the 18S and 5S ribosomal RNA genes in Astyanax altiparanae Garutti & Britski, 2000 (Teleostei, Characidae) from the upper Paraná river basin, Brazil

open access: yesGenetics and Molecular Biology, 2006
Fluorescence in situ hybridization (FISH) was undertaken in order to determinate the chromosomal distribution pattern of 18S and 5S ribosomal DNAs (rDNA) in four populations of the characid fish Astyanax altiparanae from the upper Paraná river basin ...

The Utility of Graph Clustering of 5S Ribosomal DNA Homoeologs in Plant Allopolyploids, Homoploid Hybrids, and Cryptic Introgressants

open access: yesFrontiers in Plant Science, 2020
IntroductionRibosomal DNA (rDNA) loci have been widely used for identification of allopolyploids and hybrids, although few of these studies employed high-throughput sequencing data.
