The 5′ end of the 18S rRNA can be positioned from within the mature rRNA [PDF]

RNA, 1999
In yeast, the 5' end of the mature 18S rRNA is generated by endonucleolytic cleavage at site A1, the position of which is specified by two distinct signals. An evolutionarily conserved sequence immediately upstream of the cleavage site has previously been shown to constitute one of these signals.

Characterising the Canine Oral Microbiome by Direct Sequencing of Reverse-Transcribed rRNA Molecules. [PDF]

PLoS ONE, 2016
PCR amplification and sequencing of phylogenetic markers, primarily Small Sub-Unit ribosomal RNA (SSU rRNA) genes, has been the paradigm for defining the taxonomic composition of microbiomes.

The Bowen–Conradi syndrome protein Nep1 (Emg1) has a dual role in eukaryotic ribosome biogenesis, as an essential assembly factor and in the methylation of Psi1191 in yeast 18S rRNA [PDF]

, 2010
The Nep1 (Emg1) SPOUT-class methyltransferase is an essential ribosome assembly factor and the human Bowen–Conradi syndrome (BCS) is caused by a specific Nep1D86G mutation. We recently showed in vitro that Methanocaldococcus jannaschii Nep1 is a sequence-

Rlp7p is associated with 60S preribosomes, restricted to the granular component of the nucleolus, and required for pre-rRNA processing [PDF]

, 2002
Many analyses have examined subnucleolar structures in eukaryotic cells, but the relationship between morphological structures, pre-rRNA processing, and ribosomal particle assembly has remained unclear.

The Protist Ribosomal Reference database (PR2): a catalog of unicellular eukaryote Small Sub-Unit rRNA sequences with curated taxonomy [PDF]

, 2012
The interrogation of genetic markers in environmental meta-barcoding studies is currently seriously hindered by the lack of taxonomically curated reference data sets for the targeted genes.

Regulatory Aspects of rRNA Modification and Pre-rRNA Processing

, 2014
The major types of posttranscriptional modification are the isomerization of uracil to pseudouridine, 2′-O-methylation of the ribose moieties and base methylation. In addition to their roles in pre-rRNA modification, both Dim1p and Cbf5p are required for pre-rRNA processing, and Pet56p is required for synthesis of mitochondrial large ribosomal subunits.

Identification of a structural motif of 23S rRNA interacting with 5S rRNA

FEBS Letters, 2001
To identify RNA motifs interacting with 5S rRNA, a systematic evolution of ligands by exponential enrichment experiment was applied. Some of the resulting RNA aptamers contained a consensus sequence similar to the sequence in the loop region of helix 89 of 23S rRNA.
