DNA replication stress restricts ribosomal DNA copy number. [PDF]

open access: yesPLoS Genetics, 2017
Ribosomal RNAs (rRNAs) in budding yeast are encoded by ~100-200 repeats of a 9.1kb sequence arranged in tandem on chromosome XII, the ribosomal DNA (rDNA) locus.

Ribosomal DNA Copy Number Variation is Coupled with DNA Methylation Changes at the 45S rDNA Locus [PDF]

open access: yesEpigenetics, 2023
The human ribosomal DNA (rDNA) copy number (CN) has been challenging to analyse, and its sequence has been excluded from reference genomes due to its highly repetitive nature. The 45S rDNA locus encodes essential components of the cell, nevertheless rDNA

RNA polymerase I mutant affects ribosomal RNA processing and ribosomal DNA stability [PDF]

open access: yesRNA Biology
Transcription is a major contributor to genomic instability. The ribosomal RNA (rDNA) gene locus consists of a head-to-tail repeat of the most actively transcribed genes in the genome.

CX-5461 Preferentially Induces Top2α-Dependent DNA Breaks at Ribosomal DNA Loci [PDF]

open access: yesBiomedicines
While genotoxic chemotherapeutic agents are among the most effective tools to combat cancer, they are often associated with severe adverse effects caused by indiscriminate DNA damage in non-tumor tissue as well as increased risk of secondary ...

Isolation and study of morphology and phylogeny of arbuscular mycorrhizal fungi coexisting with the roots of some medicinal plants in Kerman province [PDF]

open access: yesمجله بیوتکنولوژی کشاورزی, 2020
Objective Plants that have a symbiotic relationship with arbuscular mycorrhizal fungi (AMF) compared with non-mycorrhizal plants have a higher ability to resist against various biotic and abiotic environmental stresses such as drought, salinity, pests ...

Evaluation of the complete nuclear rDNA unit sequence of the jellyfish Cyanea nozakii Kishinouye (Scyphozoa: Semaeostomeae) for molecular discrimination

open access: yesAnimal Cells and Systems, 2021
The harmful jellyfish Cyanea nozakii Kishinouye has frequently occurred on Korean coasts, and its blooms have caused serious ecological and economic damages. DNA sequences of the C. nozakii for molecular detection and discrimination are relatively scarce.

Challenges and Approaches to Genotyping Repetitive DNA

open access: yesG3: Genes, Genomes, Genetics, 2020
Individuals within a species can exhibit vast variation in copy number of repetitive DNA elements. This variation may contribute to complex traits such as lifespan and disease, yet it is only infrequently considered in genotype-phenotype associations ...
