Intermolecular mRNA - rRNA hybridization and the distribution of potential interaction regions in murine 18s rRNA

open access: yesNucleic Acids Research, 1993
Intermolecular hybridization experiments show that murine 18S rRNA and 28S rRNA are capable of forming stable hybrid structures with mRNA from genes p53, c-myc and c-mos from the same species. Both 5'-uncoding and coding oncogene p53 mRNA regions contain fragments interacting with rRNA.

Séance: reference-based phylogenetic analysis for 18S rRNA studies [PDF]

open access: yesBMC Evolutionary Biology, 2014
Marker gene studies often use short amplicons spanning one or more hypervariable regions from an rRNA gene to interrogate the community structure of uncultured environmental samples. Target regions are chosen for their discriminatory power, but the limited phylogenetic signal of short high-throughput sequencing reads precludes accurate phylogenetic ...

Nitrate Consumers in Arctic Marine Eukaryotic Communities: Comparative Diversities of 18S rRNA, 18S rRNA Genes, and Nitrate Reductase Genes [PDF]

open access: yesApplied and Environmental Microbiology, 2019
To better understand the diversity of primary producers in the Arctic Ocean, we targeted a nitrogen cycle gene, NR, which is required for phytoplankton to assimilate nitrate into organic forms of nitrogen macromolecules. We compared this to the more detailed taxonomy from ice-influenced stations using a general taxonomic gene (18S rRNA).

Retrieval of a million high-quality, full-length microbial 16S and 18S rRNA gene sequences without primer bias

open access: yesNature Biotechnology, 2018
Small subunit ribosomal RNA (SSU rRNA) genes, 16S in bacteria and 18S in eukaryotes, have been the standard phylogenetic markers used to characterize microbial diversity and evolution for decades.

The small-subunit processome is a ribosome assembly intermediate [PDF]

open access: yes, 2004
The small-subunit (SSU) processome is a large ribonucleoprotein required for the biogenesis of the 18S rRNA and likely corresponds to the terminal knobs visualized by electron microscopy on the 5' end of nascent rRNAs.

Thermophile 90S Pre-ribosome Structures Reveal the Reverse Order of Co-transcriptional 18S rRNA Subdomain Integration.

open access: yesMolecules and Cells, 2019
Eukaryotic ribosome biogenesis involves RNA folding and processing that depend on assembly factors and small nucleolar RNAs (snoRNAs). The 90S (SSU-processome) is the earliest pre-ribosome structurally analyzed, which was suggested to assemble stepwise ...

Monophyly of brachiopods and phoronids: reconciliation of molecular evidence with Linnaean classification (the subphylum Phoroniformea nov.) [PDF]

open access: yes, 2000
Molecular phylogenetic analyses of aligned 18S rDNA gene sequences from articulate and inarticulate brachiopods representing all major extant lineages, an enhanced set of phoronids and several unrelated protostome taxa, confirm previous indications that ...

Molecular characterization of Sarcocystis species isolated from Chinese buffaloes in Guizhou province based on 18S rRNA and cox1 sequences

open access: yesMitochondrial DNA. Part B. Resources, 2019
The parasites from buffaloes in Guizhou province, southwest China, were suspected to be sarcocysts through morphologic observation. 18S rRNA and the subunit I of cytochrome oxidase (cox1) sequences were amplified, then implemented by phylogenetic ...

A comprehensive fungi-specific 18S rRNA gene sequence primer toolkit suited for diverse research issues and sequencing platforms

open access: yesBMC Microbiology, 2018
Several fungi-specific primers target the 18S rRNA gene sequence, one of the prominent markers for fungal classification. The design of most primers goes back to the last decades.
