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

Aquaculture 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.

PLoS 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.

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

Frontiers 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.

The long-range interaction map of ribosomal DNA arrays. [PDF]

PLoS Genetics, 2018
The repeated rDNA array gives rise to the nucleolus, an organelle that is central to cellular processes as varied as stress response, cell cycle regulation, RNA modification, cell metabolism, and genome stability.

Ribosomal DNA copy number amplification and loss in human cancers is linked to tumor genetic context, nucleolus activity, and proliferation.

PLoS Genetics, 2017
Ribosomal RNAs (rRNAs) are transcribed from two multicopy DNA arrays: the 5S ribosomal DNA (rDNA) array residing in a single human autosome and the 45S rDNA array residing in five human autosomes.

Genetic diversity of ribosomal loci (5S and 45S rDNA) and pSc119.2 repetitive DNA sequence among four species of Aegilops (Poaceae) from Algeria

Ukrainian Botanical Journal, 2021
In continuation of our previous research we carried out the karyological investigation of 53 populations of four Aegilops species (A. geniculata, A. triuncialis, A. ventricosa, and A.

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

Nucleic 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 ...

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

Genetics 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 ...

Large-scale comparative analysis of cytogenetic markers across Lepidoptera

Scientific Reports, 2021
Fluorescence in situ hybridization (FISH) allows identification of particular chromosomes and their rearrangements. Using FISH with signal enhancement via antibody amplification and enzymatically catalysed reporter deposition, we evaluated applicability ...

Insights Into the Origin and Local Adaptation Evolution of the Cultivated Sesame With Telomere‐to‐Telomere High‐Quality Genome

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sesame (Sesamum indicum L., 2n = 26) is one of the oldest oilseed crops and is often called the ‘queen of oilseeds’ due to its high content of unsaturated fatty acids and natural antioxidants. Despite its long history, the origin and global spread of cultivated sesame remain unresolved.
