Regulation of Arabidopsis thaliana 5S rRNA Genes.
The Arabidopsis thaliana genome comprises around 1,000 copies of 5S rRNA genes encoding both major and minor 5S rRNAs. In mature wild-type leaves, the minor 5S rRNA genes are silent. Using different mutants of DNA methyltransferases (met1, cmt3 and met1 cmt3), components of the RNAi pathway (ago4) or post-translational histone modifier (hda6/sil1), we show that the corresponding proteins are ne...
متن کاملDicistronic tRNA–5S rRNA genes in Yarrowia lipolytica: an alternative TFIIIA-independent way for expression of 5S rRNA genes
In eukaryotes, genes transcribed by RNA polymerase III (Pol III) carry their own internal promoters and as such, are transcribed as individual units. Indeed, a very few cases of dicistronic Pol III genes are yet known. In contrast to other hemiascomycetes, 5S rRNA genes of Yarrowia lipolytica are not embedded into the tandemly repeated rDNA units, but appear scattered throughout the genome. We ...
متن کاملCompilation of 5S rRNA and 5S rRNA gene sequences
This is an update for the 5S rRNA sequences of the BERLIN RNA DATABANK last published in 1990 (1). The new entry consists of 25 eubacterial and 2 eukaryotic 5S rRNA sequences and 10 plant 5S rRNA pseudogenes (Table 1). Thus the BERLIN RNA DATABANK contains as of February 1, 1991 the 5S rRNA sequences of 44 archaebacteria, 292 eubacteria, 20 plastids, 6 mitochondria, 321 eukaryotes and 21 eukary...
متن کامل5S rRNA Data Bank
In this paper we present the updated version of the compilation of 5S rRNA and 5S rDNA nucleotide sequences. It contains 1622 primary structures of 5S rRNAs and 5S rRNA genes from 888 species. These include 58 archaeal, 427 eubacterial, 34 plastid, nine mitochondrial and 1094 eukaryotic DNA or RNA nucleotide sequences. The sequence entries are divided according to the taxonomic position of the ...
متن کاملPhysical mapping of the 5S rRNA in the common sea urchin, Paracentrotus lividus (Echinodermata: Echinoidea), by in situ hybridization.
Locations of the 5S rRNA genes (rDNA) are usually considered to be helpful, as generally invariable chromosome markers, especially if chromosome banding is not possible. The genes have been defined in about 90 invertebrate species, and were found linked to other multigene families in genomes of some nematodes and arthropods (Drouin and Moniz de Sa, 1995; Barzotti et al., 2000). They were also f...
