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 …

The nucleus is undoubtedly the most complex organelle in the eukaryotic cell. The master
genetic library of the cell, it contains 1–2 m of double-stranded DNA packed in the form of …

This review gives an inventory of 58 computer‐aided three‐dimensional reconstruction
applications in the domain of biomedical research. It is devoted to the formulation of a set of …

Pollen embryogenesis has been induced in Capsicum annuum L., selecting the late
vacuolate microspore as the suitable developmental stage for the induction. Various modern …

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 …

Nucleolar transcription in isolated onion cell nuclei was visualized, after Br-UTP
incorporation, under the conventional fluorescence microscope, the confocal microscope …

This study of the effect of cadmium on nucleolar ultrastructure was carried out with
meristematic cell populations of Allium cepa L. Meristems, grown at 25° C, were treated with …

For the purpose of gaining knowledge of the relationships between cell proliferation and
ribosome biogenesis, as two fundamental mutually interconnected cellular processes …

Intranucleolar DNA, including ribosomal DNA (rDNA), was localized in situ in proliferating
onion cells under the electron microscope using an anti-DNA monoclonal antibody and a …

We investigated how only three morphologically distinguished nucleolar components can
integrate the many necessary tasks in ribosome biogenesis. For the mapping of ribosomal …
