Cytogenetic markers using single-sequence probes reveal chromosomal locations of tandemly repetitive genes in scleractinian coral Acropora pruinosa

open access: yesScientific Reports, 2021
The short and similar sized chromosomes of Acropora pose a challenge for karyotyping. Conventional methods, such as staining of heterochromatic regions, provide unclear banding patterns that hamper identification of such chromosomes.

Role of the RNA-binding protein ZC3H41 in the regulation of ribosomal protein messenger RNAs in trypanosomes

open access: yesParasites & Vectors, 2023
Background Trypanosomes are single-celled eukaryotes that rely heavily on post-transcriptional mechanisms to regulate gene expression. RNA-binding proteins play essential roles in regulating the fate, abundance and translation of messenger RNAs (mRNAs ...

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.

Amplification and adaptation of centromeric repeats in polyploid switchgrass species. [PDF]

open access: yes, 2018
Centromeres in most higher eukaryotes are composed of long arrays of satellite repeats from a single satellite repeat family. Why centromeres are dominated by a single satellite repeat and how the satellite repeats originate and evolve are among the most

Organization and expression analysis of 5S and 45S ribosomal DNA clusters in autotetraploid Carassius auratus

open access: yesBMC Ecology and Evolution, 2021
Background Autotetraploid Carassius auratus (4n = 200, RRRR) (abbreviated as 4nRR) is derived from whole genome duplication of Carassius auratus red var. (2n = 100, RR) (abbreviated as RCC).

Early evolutionary colocalization of the nuclear ribosomal 5S and 45S gene families in seed plants: evidence from the living fossil gymnosperm Ginkgo biloba [PDF]

open access: yes, 2012
In seed plants, the colocalization of the 5S loci within the intergenic spacer (IGS) of the nuclear 45S tandem units is restricted to the phylogenetically derived Asteraceae family. However, fluorescent in situ hybridization (FISH) colocalization of both

5S Ribosomal RNA data bank

open access: yesNucleic Acids Research, 1999
This paper presents the updated version of the data base of ribosomal 5S ribonucleic acids (5S rRNA) and their genes (5S rDNA). This edition of the data bank contains 1889 primary structures of 5S rRNA and 5S rDNA. These include 60 archaebacterial, 439 eubacterial, 63 plastid, 9 mitochondrial and 1318 eukaryotic sequences.
