Regulatory roles of nucleolus organizer region-derived long non-coding RNAs. [PDF]
Mamm Genome, 2022 The nucleolus is the largest sub-nuclear domain, serving primarily as the place for ribosome biogenesis. A delicately regulated function of the nucleolus is vital to the cell not only for maintaining proper protein synthesis but is also tightly associated with responses to different types of cellular stresses.

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

Cytogenetic and identification of the nucleolus organizer region in Heliconia bihai (L.) L. [PDF]
Revista Ceres, 2014 The genus Heliconia is not much studied and the number of existing species in this genus is still uncertain. It is known that this number relies between 150 to 250 species. In Brazil, about 40 species are native and known by many different names.

Acta Herpetologica, 2007 The karyotype of Typhlops brongersmianus is reported on the basis of specimens from north-eastern Argentina. The conventional Giemsa staining showed that the species has 2n = 34 chromosomes, including 8 pairs of macrochromosomes and 9 pairs of ...

Chicken rRNA Gene Cluster Structure. [PDF]
PLoS ONE, 2016 Ribosomal RNA (rRNA) genes, whose activity results in nucleolus formation, constitute an extremely important part of genome. Despite the extensive exploration into avian genomes, no complete description of avian rRNA gene primary structure has been ...

Elucidation of motifs in ribosomal protein S9 that mediate its nucleolar localization and binding to NPM1/nucleophosmin. [PDF]
PLoS ONE, 2012 Biogenesis of eukaryotic ribosomes occurs mainly in a specific subnuclear compartment, the nucleolus, and involves the coordinated assembly of ribosomal RNA and ribosomal proteins.

Genetics and Molecular Biology, 2007 Chromosome analyses were performed in two grasshopper species of the genus Schistocerca, S. pallens and S. flavofasciata. Both species shared the same diploid number (2n = 23, X in males; 2n = 24, XX in females);and a conserved karyotype composed ...

QUANTITATIVE STUDY OF GASTRIC EPITHELIAL LESIONS BY NUCLEOLAR ORGANIZER REGION STAINING [PDF]
Acta Medica Iranica, 2004 Nucleolar organizer regions (NOR) are defined as nucleolar components containing a set of argyrophilic proteins which are selectively stained by colloidal silver nitrate staining.
