Molecular structure of 5S rDNA of Mandragora autumnalis Bertol.

Visnik ukrains'kogo tovaristva genetikiv i selekcioneriv, 2020
Aim. The region encoding 5S rRNA (5S rDNA) is present in the genome of all eukaryotic organisms. The 5S rDNA represents a universal model for studying the molecular evolution of the tandemly arranged repeated sequences. However, in the family Solanaceae, the molecular organization of 5S rDNA has been investigated only for few genera. In this regard, we

Variations in 5S rDNAs in diploid and tetraploid offspring of red crucian carp × common carp

BMC Genetics, 2017
Background The allotetraploid hybrid fish (4nAT) that was created in a previous study through an intergeneric cross between red crucian carp (Carassius auratus red var., ♀) and common carp (Cyprinus carpio L., ♂) provided an excellent platform to ...

Modification of the Transcription Factor FOXL2 at Serines 101 and 107 Disables DNA Binding, Leads to Nucleolar Relocalization, and Rewires Granulosa‐Cell Programs

The FASEB Journal, Volume 40, Issue 15, 15 August 2026.
PKC‐mediated phosphorylation of FOXL2 weakens DNA binding, alters subnuclear localization and protein interactions, and reshapes FOXL2‐dependent transcriptional programs in granulosa cells, supporting a reversible mechanism that modulates FOXL2 activity through phosphorylation of its DNA‐binding domain. ABSTRACT FOXL2 is a forkhead transcription factor

Single Copies of the 5S rRNA Inserted into 45S rDNA Intergenic Spacers in the Genomes of Nototheniidae (Perciformes, Actinopterygii)

, 2023
In the vast majority of Animalia genomes, the 5S rRNA gene repeats are located on chromosomes outside of the 45S rDNA arrays of the nucleolar organiser (NOR).

FISH-mapping of the 5S rDNA locus in chili peppers (Capsicum-Solanaceae) [PDF]

Anais da Academia Brasileira de Ciências, 2016
ABSTRACT We present here the physical mapping of the 5S rDNA locus in six wild and five cultivated taxa of Capsicum by means of a genus-specific FISH probe. In all taxa, a single 5S locus per haploid genome that persistently mapped onto the short arm of a unique metacentric chromosome pair at intercalar position, was found.

Nuclear pore links Fob1‐dependent rDNA damage relocation to lifespan control

FEBS Open Bio, Volume 16, Issue 7, Page 1305-1313, July 2026.
Damaged rDNA accumulates at a specific perinuclear interface that couples nucleolar escape with nuclear envelope association. Nuclear pores at this site help inhibit Fob1‐induced rDNA instability. This spatial organization of damage handling supports a functional link between nuclear architecture, rDNA stability, and replicative lifespan in yeast.

Systematic analysis and evolution of 5S ribosomal DNA in metazoans [PDF]

, 2013
Several studies on 5S ribosomal DNA (5S rDNA) have been focused on a subset of the following features in mostly one organism: number of copies, pseudogenes, secondary structure, promoter and terminator characteristics, genomic arrangements, types of non ...

Ribosomal DNA localization on Lathyrus species chromosomes by FISH

Journal of Genetic Engineering and Biotechnology, 2020
Background Fluorescence In Situ Hybridization (FISH) played an essential role to locate the ribosomal RNA genes on the chromosomes that offered a new tool to study the chromosome structure and evolution in plant. The 45S and 5S rRNA genes are independent

rDNAmine: A New Tool for the Analysis of Long Repetitive Sequences

Yeast, Volume 43, Issue 4, Page 170-183, July 2026.
This work introduces a novel approach for analysing long repetitive genomic sequences, combining a method to isolate large DNA molecules from individual chromosomes. We also describe the bioinformatics tool rDNAmine, which enables the isolation of long‐repeat sequences from reads obtained using the Oxford Nanopore method, as well as their preliminary ...
