18S-NemaBase: Curated 18S rRNA Database of Nematode Sequences [PDF]
Journal of Nematology, 2023 Nematodes are the most abundant and diverse animals on the planet but lack representation in biodiversity research. This presents a problem for studying nematode diversity, particularly when molecular tools (i.e., barcoding and metabarcoding) rely on ...

Regulation of translation by methylation multiplicity of 18S rRNA [PDF]
Cell Reports, 2021 Summary: N6-methyladenosine (m6A) is a conserved ribonucleoside modification that regulates many facets of RNA metabolism. Using quantitative mass spectrometry, we find that the universally conserved tandem adenosines at the 3′ end of 18S rRNA, thought ...

Cell Reports, 2019 Summary: 18S non-functional rRNA decay (NRD) eliminates non-functional 18S rRNA with deleterious mutations in the decoding center. Dissociation of the non-functional 80S ribosome into 40S and 60S subunits is a prerequisite step for degradation of the non-

pr2-primers: an 18S rRNA primer database for protists
Molecular Ecology Resources, 2021 Metabarcoding of microbial eukaryotes (collectively known as protists) has developed tremendously in the last decade, almost uniquely relying on the 18S rRNA gene.

metaPR2 : A database of eukaryotic 18S rRNA metabarcodes with an emphasis on protists. [PDF]
Mol Ecol Resour, 2022 In recent years, metabarcoding has become the method of choice for investigating the composition and assembly of microbial eukaryotic communities, and an increasing number of environmental datasets are being published. Although unprocessed sequence files

Arabidopsis HOT3/eIF5B1 constrains rRNA RNAi by facilitating 18S rRNA maturation. [PDF]
Proc Natl Acad Sci U S A, 2023 Ribosome biogenesis is essential for protein synthesis in gene expression. Yeast eIF5B has been shown biochemically to facilitate 18S ribosomal RNA (rRNA) 3′ end maturation during late-stage 40S ribosomal subunit assembly and gate the transition from translation initiation to elongation.

METTL5-mediated 18S rRNA m6A modification promotes oncogenic mRNA translation and intrahepatic cholangiocarcinoma progression. [PDF]
Mol Ther, 2023 Intrahepatic cholangiocarcinoma (ICC) is a deadly cancer with rapid tumor progression. While hyperactive mRNA translation caused by mis-regulated mRNA or tRNA modifications promotes ICC development, the role of rRNA modifications remains elusive.

18S rRNA methyltransferases DIMT1 and BUD23 drive intergenerational hormesis. [PDF]
Mol Cell, 2023 Heritable non-genetic information can regulate a variety of complex phenotypes. However, what specific non-genetic cues are transmitted from parents to their descendants are poorly understood. Here, we perform metabolic methyl-labeling experiments to track the heritable transmission of methylation from ancestors to their descendants in the nematode ...

Taxonomic resolutions based on 18S rRNA genes: a case study of subclass copepoda. [PDF]
PLoS ONE, 2015 Biodiversity studies are commonly conducted using 18S rRNA genes. In this study, we compared the inter-species divergence of variable regions (V1-9) within the copepod 18S rRNA gene, and tested their taxonomic resolutions at different taxonomic levels ...

Poly(G)7 box: a functional element of mammalian 18S rRNA involved in translation [PDF]
RNA BiologyIn eukaryotes, the ribosomal small subunit (40S) is composed of 18S rRNA and 33 ribosomal proteins. 18S rRNA has a special secondary structure and is an indispensable part of the translation process.
