Comparative analysis of RNA sequences is the basis for the detailed and accurate predictions of RNA structure and the determination of phylogenetic relationships for organisms that span the entire phylogenetic tree. Underlying these accomplishments are very large, well-organized, and processed collections of RNA sequences. This data, starting with the(More)
Comparative modeling of secondary structure is a proven approach to predicting higher order structural elements in homologous RNA molecules. Here we present the results of a comprehensive comparison of newly modeled or refined secondary structures for the cytoplasmic large subunit (23 S-like) rRNA of eukaryotes. This analysis, which covers a broad(More)
We report the complete nucleotide sequence of the Tetrahymena pyriformis mitochondrial genome and a comparison of its gene content and organization with that of Paramecium aurelia mtDNA. T. pyriformis mtDNA is a linear molecule of 47,172 bp (78.7 % A+T) excluding telomeric sequences (identical tandem repeats of 31 bp at each end of the genome). In addition(More)
This compilation is part of an on-going effort to maintain a comprehensive and continually updated collection of large subunit (LSU; 23S and 23S-like) rRNA secondary structures and associated sequence and citation information. Table 1 gives a breakdown of the number and phylogenetic distribution of sequences currently in this LSU rRNA database. A listing of(More)
The mitochondrial genome of Plasmodium falciparum encodes highly fragmented rRNAs. Twenty small RNAs which are putative rRNA fragments have been found and 15 of them have been identified as corresponding to specific regions of rRNA sequence. To investigate the possible interactions between the fragmented rRNAs in the ribosome, we have mapped the ends of(More)
Mollusks are an extraordinarily diverse group of animals with an estimated 200,000 species, second only to the phylum Arthropoda. We conducted a comparative analysis of complete mitochondrial ribosomal large subunit sequences (LSU) of a chiton, two bivalves, six gastropods, and a cephalopod. In addition, we determined secondary structure models for each of(More)
Dinoflagellates comprise an ecologically significant and diverse eukaryotic phylum that is sister to the phylum containing apicomplexan endoparasites. The mitochondrial genome of apicomplexans is uniquely reduced in gene content and size, encoding only three proteins and two ribosomal RNAs (rRNAs) within a highly compacted 6 kb DNA. Dinoflagellate(More)
The chloroplast large subunit rRNA gene of Chlamydomonas eugametos and its 5' flanking region encoding tRNA(Ile) (GAU) and tRNA(Ala) (UGC) have been sequenced. The DNA sequence data along with the results of a detailed RNA analysis disclosed two unusual features of this green algal large subunit rRNA gene: (1) the presence of six group I introns(More)

In eukaryotes, box H/ACA small nucleolar RNAs (snoRNAs) guide sites of pseudouridine (Psi) formation in rRNA. These snoRNAs reside in RNP complexes containing the putative Psi synthase, Cbf5p. In this study we have identified Cbf5p-associated RNAs in Euglena gracilis, an early diverging eukaryote, by immunoprecipitating Cbf5p-containing complexes from(More)
