We have determined the nucleotide sequence of ribosomal 5S RNA from bovine liver. The comparison of this sequence with those from other cukaryotic sources shows that a common secondary structure model for all eukaryotic 5S rRNAs may exist Analysis of the evolutionary conserved nucleotides in metazoan 5S rRNAs suggests that the tertiary interactions, proposed earlier for plant 5S rRNA, are also possible.

We have estimated the number of 5S rRNA genes in Aspergillus nidulans using two-dimensional agarose gel electrophoresis and hybridization to appropriate probes, representing the 5'-halves, the 3'-halves of the 5S rRNA sequence and a sequence found at the 3'-end of all known A. nidulans pseudogenes (block C). We have found 23 5S rRNA genes, 15 pseudogenes consisting of the 5'-half of the 5S rRNA sequence (of which 3 are flanked by block C) and 12 copies of block C which do not seem to be in the vicinity of 5S rRNA sequences. This number of genes is much lower than our earlier estimates, and makes our previously analyzed sample of 9 sequenced genes and 3 pseudogenes much more representative.

There are regions in rRNA which are evolutionary conserved and exposed on ribosomal surface. We selected in plant material (Lupinus luteus) two of them: the α-sarcin domain of 26S rRNA (L-rRNA) and C loop of 5S rRNA, to be further investigated using antisense oligomers as research tools. We found inhibition of the model polypeptide biosynthesis (up to 80%) due to specific hybridization of oligomers addressed to α-sarcin domain and loop C. Based on our results we present the evidence for the key role played by these regions of rRNAs during protein biosynthesis in plant system. According to our hypothesis, conformational changes of these two regions are synchronised and cooperative during transition of pre- to post-translocation state of the ribosome. The correlation of structure and activity of rRNA domains in translation is shown.

W pracy oceniono przydatność reakcji amplifikacji fragmentów bakteryjnego DNA w rozpoznawaniu infekcyjnego zapalenia wsierdzia o etiologii bakteryjnej oraz określono swoistość i czułość reakcji. Do amplifikacji wybranych fragmentów bakteryjnego DNA wykorzystywano swoiste startery F/R dla konserwatywnego regionu kodującego obszar 16S rRNA Procaryota. Wykazano, że świeża krew oraz surowica są lepszymi w stosunku do krwi zamrażanej (-20°C) materiałami do badania. Uzyskane wyniki wskazują, że zastosowana metoda PCR jest przydatna do identyfikacji bakteryjnych czynników zakażenia.

In contrast to mRNAs, ribosomal RNAs are generally not considered to be polyadenylated. Only a few recent reports describe non-abundant polyadenylated rRNA-related transcripts that have been detected and characterized in yeast and in human cells. Here we depict the phenomenon of 26S rRNA polyadenylation and degradation that was observed in shoots of Nicotiana tabaccum plants grown in the presence of cadmium. Fragments corresponding to 26S rRNA were identified using suppression subtractive hybridization during screening for genes induced in tobacco plants upon a three-week exposure to 15 μM cadmium chloride. Extracts prepared from the above-ground tissues of cadmium-treated tobacco plants were supposed to contain exclusively polyadenylated mRNAs. Surprisingly, numerous polyadenylated fragments matching parts of 26S rRNA were identified and their presence was confirmed by Northern blot and cDNA amplification techniques. To our knowledge this is the first report on rRNA polyadenylation in plants

In order to perform a phylogenetic analysis of Nosema spp. spores, samples of 10 worker bees each were collected from 30 infected colonies (the presence of spores was confirmed by light microscopy) kept in 15 apiaries in north-eastern Poland. Both N. apis and N. ceranae are common in this region (mixed infection N. apis/ N. ceranae – 60%, N. ceranae – 37%, N. apis – 3%). The DNA samples of N. apis were 100% identical with the N. apis sequences deposited in the GenBank database in Queensland, Australia, Spain, New Zealand, Lithuania and Tasmania in Australia. The DNA samples of N. ceranae were found to be 99.5%-100% identical with the N. ceranae sequences previously published in Italy, Germany, Switzerland and Austria.
