Genetic linkage map of the nucleolus organizer region in the soybean. [PDF]

open access: yesGenetics, 2008
Abstract Simple polymorphisms in ribosomal DNA repeats in the nucleolus organizer region (NOR) permitted the development of markers for the genetic mapping of the soybean NOR. The markers map to the top end of soybean linkage group F, one of either telomeric end predicted in the cytogenetic and primary trisomic studies.

The human nucleolus organizer regions [PDF]

open access: yesGenes & Development, 2019
Although the nucleolus was first described in the early 19th century from both animal and plant cells, human nucleoli and particularly the five human nucleolus organizers have not been well characterized. In this issue of Genes & Development, van Sluis and colleagues (pp.

Ribosomal RNA genes shape chromatin domains associating with the nucleolus

open access: yesNucleus, 2019
Genomic interactions can occur in addition to those within chromosome territories and can be organized around nuclear bodies. Several studies revealed how the nucleolus anchors higher order chromatin structures of specific chromosome regions displaying ...

Karyotype and chromosomal characteristics of rDNA of Cobitis strumicae Karaman, 1955 (Teleostei, Cobitidae) from Lake Volvi, Greece [PDF]

open access: yesComparative Cytogenetics, 2018
The karyotype of Greek cobitid fish Cobitis strumicae Karaman, 1955, from Lake Volvi, Greece, a representative of one of its two major intraspecific phylogenetic lineages, was analysed by means of sequential Giemsa-staining, C-banding, silver-staining ...

Looking for genetic effects of polluted anthropized environments on Caiman crocodilus crocodilus (Reptilia, Crocodylia): A comparative genotoxic and chromosomal analysis

open access: yesEcotoxicology and Environmental Safety, 2021
The Amazon aquatic ecosystems have been modified by the human population growth, going through changes in their water bodies and aquatic biota. The spectacled alligator (Caiman crocodilus crocodilus) has a wide distribution and adaptability to several ...

Nucleolus organizer regions and nucleoli in preattachment bovine embryos [PDF]

open access: yesReproduction, 1988
Summary. Embryos (1-cell to elongated blastocyst stage) were recovered from super-ovulated heifers at surgery (Days 2–4; oestrus = Day 0), after slaughter (Day 4), or by transcervical flushing (Days 6, 7 and 14). The 175 embryos were cultured for 4, 8, 24 or 48 h, fixed on slides and sequentially stained with Giemsa and silver nitrate.

Alteration of rRNA gene copy number and expression in patients with intellectual disability and heteromorphic acrocentric chromosomes

open access: yesEgyptian Journal of Medical Human Genetics, 2018
Background: Intellectual disability (ID) is an important medical and social problem that can be caused by different genetic and environmental factors. One such factor could be rDNA amplification and changes in rRNA expression and maturation.

Exfoliative Cytology in the Oral Mucosa of Patients with Fanconi Anaemia: A Morphometric Approach

open access: yesJournal of Dentistry Indonesia, 2017
Patients with Fanconi anaemia (FA) are prone to develop squamous cell carcinomas at an early age. Exfoliative cytology can be used to detect changes to the health of the oral mucosa.
