Nucleoli are the sites of biosynthesis of the ribosomal precursors. They contain may copies
of the genes for the main rRNAs (18 S-and 28 S-rRNA) in the form of tandemly arranged …

Nucleoli are nuclear domains present in almost all eukaryotic cells. They not only specialize
in the production of ribosomal subunits but also play roles in many fundamental cellular …

This review addresses the problem of understanding nucleolar morphology in terms of
nucleolar function. Nucleolar morphology and function are outlined to serve as a basis for …

The physical location of the rDNA repeating units (25 S, 18 S and 5.8 S rRNA genes and the
intergenic spacer sequences) was investigated in rye (Secale cereale L.) and wheat …

Recently, the ribosomes—molecularly well-characterized cell organelles where the process
of translation of messenger RNA into polypeptides occurs—have attracted new interest …

The nucleolus, the site of ribosomal RNA synthesis, provides us with one of the best
opportunities for unravelling the relationships between transcription and the spatial …

We have used polyclonal and monoclonal antibodies against different lamins from
vertebrates, and the IFA antibody recognizing all kinds of intermediate filament proteins, to …

The nucleolus is a prominent nuclear organelle which morphologically expresses all
functional steps necessary for the synthesis of ribosomes, from transcription of rRNA genes …

Positional and structural modifications were demonstrated in nuclei of leek cells, after
establishment of a symbiosis with two vesicular-arbuscular fungi, Glomus versiforme …

The nucleolus is a nuclear substructure that is well known as the ribosome factory of the cell,
namely, the site in which the production of mature ribosomal subunits takes place before …
