The effects of different concentrations of Al (10 μM, 50 μM, 100 μM) on nucleoli in root tip cells, root growth, antioxidant enzyme activity and malondialdehyde (MDA) content were investigated in hydroponically grown Vicia faba L. Aluminum significantly inhibited root growth of V. faba treated with 50 μM and 100 μM Al. In the nucleolus in root tip cells, some particulates containing argyrophilic proteins were extruded from the nucleus into the cytoplasm, and some were scattered in the nucleus after Al stress. Superoxide dismutase (SOD) activity in leaves and roots exposed to different concentrations of Al was mostly higher than in the control. Seedlings exposed to 100 μM Al showed significantly higher peroxidase (POD) activity in roots than in the control. POD activity increased much more in roots than in leaves. Catalase (CAT) activity was lower in roots than in leaves. Malondialdehyde (MDA) content in leaves and roots of plants exposed to 50 μM and 100 μM Al was significantly higher than in the other groups and the control at 6 to 9 days of treatment. These results suggest that alterations in nucleoli and altered antioxidant enzyme activity and MDA content in V. faba can serve as useful biomarkers for detection of Al toxicity. The mechanisms of Al toxicity and tolerance in V. faba are briefly discussed

The aim of this study was the evaluation of the influence of extremely low-frequency magnetic fields (ELF-MF) on the morphology of thyroid epithelial cells in female rats. The rats were exposed to ELF–MF (frequency: 5-10 Hz, induction 10 mT), 1 hour daily for 7 days over a week for 4 months. Control animals were sham exposed. After that time the rats were sacrificed by anaesthetizing with Ketamine and decapitated. The animals’ thyroid glands were extracted. They served as microscopic preparations. In the preparations, the thyreocytes, nuclei, nucleoli and nucleo-cytoplasmatic ratio were evaluated. We concluded that changes in the location of nuclei, surface field, the number and surface of nucleoli and nucloli organizers show an increase in reply activity in the nuclei of thyreocytes and a probable increase of DNA synthesis.

The nucleophosmin 1 gene (NPM1) encodes a multifunctional nucleolar phosphoprotein that plays a crucial role in the control of various aspects of cell growth and homeostasis. In this study, the coding region of the NPM1 gene was screened in 1035 individuals of 4 Chinese cattle breeds by DNA sequencing and Polyacrylamide gel electrophoresis. A novel 12-bp deletion mutation was identified in the coding region of the NPM1 gene. The PCR products of primer NPM1-P2 exhibited 3 genotypes and 2 alleles: 178 bp (denoted as W) and 166 bp (denoted as D). Genotype DD and allele D were predominant in the studied populations. Association analysis with growth traits in the Nanyang breed (N = 265) showed that the animals with genotype DD had significantly greater birth weight, body weight, body length, and heart girth than those with genotype WD (P <0.01 or P < 0.05) at birth and after 6 months and 12 months, but not at 18 and 24 months of age. Results of this study suggest that the NPM1 gene is a candidate gene for growth traits in cattle.

Root meristem nucleoli from soybean (Glycine max. cv. Aldana) seedlings germinated for 3 days at 25°C and then for 4 days at 10°C or still at 25°C (control) were examined. Chill was observed to reduce root meristematic zone growth 15-fold. Nucleoli doubled their volume at 10°C. Autoradiographic studies showed that after 20 min 3H-uridine incubation at 10°C, incorporation of this precursor (postincubation time 0) into nucleoli of chilled seedlings was 4.7 times weaker than in the control. After 80 min postincubation in nonradioactive medium, the cytoplasm became the most intensely labelled cell area in the control material, while in chilled roots the nucleoli were still most intensely labelled and the cytoplasm was 11 times less labelled than in the control. The increase in nucleoli volume at 10°C is suggested to result from greater cold-induced inhibition of the dynamics of maturation and transport of ribosome subunits than of rRNA synthesis dynamics. Ultrastructural studies of chilled seedling nucleoli showed a significant decrease in the fibrillar component and an increase in the granular component, forming characteristic clusters. They are supposed to correspond to shortened and condensed pre-rRNA transcription complexes (compacted "Christmas trees").

Maturation of pre-ribosomal RNA (pre-rRNA) in eukaryotic cells takes place in the nucleolus and involves a large number of cleavage events, which frequently follow alternative pathways. In addition, rRNAs are extensively modified, with the methylation of the 2'-hydroxyl group of sugar residues and conversion of uridines to pseudouridines being the most frequent modifications. Both cleavage and modification reactions of pre-rRNAs are assisted by a variety of small nucleolar RNAs (snoRNAs), which function in the form of ribonucleoprotein particles (snoRNPs). The majority of snoRNAs acts as guides directing site-specific 2'-O-ribose methylation or pseudouridine formation. Over one hundred RNAs of this type have been identified to date in vertebrates and the yeast Saccharomyces cerevisiae. This number is readily explained by the findings that one snoRNA acts as a guide usually for one or at most two modifications, and human rRNAs contain 91 pseudouridines and 106 2'-O-methyl residues. In this article we review information about the biogenesis, structure and function of guide snoRNAs.
