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

open access: yesPLoS 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.

open access: yesPLoS 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

open access: yesUkrainian 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.

rDNA 5S e rearranjos cromossômicos em Rineloricaria (Siluriformes: Loricariidae)

open access: yes, 2018
Dados citogenéticos de Loricariidae (Siluriformes) revelam uma extensiva variação de número diploide e plasticidade cromossômica no grupo. Nestes peixes, a localização in situ de sítios de rDNA 5S em regiões co-localizadas a sítios teloméricos ...

5S rDNA FISH of WT and ibm1 meiocytes.

open access: yes, 2022
FISH analysis with 5S rDNA probe (red) of WT, ibm1-4 and ibm1-6 chromosome spreads from metaphase I meiocytes. The yellow arrows indicate nonhomologous chromosome interactions in ibm1-4 and ibm1-6. Scale bar: 5 μm. (TIF)

open access: yesBMC Genet, 2015
The establishment of the bisexual fertile fish hybrid lineage including the allodiploid and allotetraploid hybrids, from interspecific hybridization of red crucian carp (Carassius auratus red var. 2n = 100, 2n = AA) (♀) × common carp (Cyprinus carpio L.

Molecular dissection of the rDNA array and of the 5S rDNA gene in Meloidogyne artiellia: phylogenetic and diagnostic implications

open access: yesMolecular and Cellular Probes, 2004
The sequence of a 13.423 nucleotide genomic fragment has been determined for the plant parasitic nematode Meloidogyne artiellia. It contains an entire rDNA cluster, the bordering intergenic regions and portions of the flanking coding regions. The sequence analysis of the rDNA repeats suggests homogeneity in M.

Large-scale comparative analysis of cytogenetic markers across Lepidoptera

open access: yesScientific 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 ...
