16S rRNA gene and 18S rRNA gene diversity in microbial mat communities in meltwater ponds on the McMurdo Ice Shelf, Antarctica

open access: yesPolar Biology, 2021
The undulating ice of the McMurdo Ice Shelf, Southern Victoria Land, supports one of the largest networks of ice-based, multiyear meltwater pond habitats in Antarctica, where microbial mats are abundant and contribute most of the biomass and biodiversity.

Quantification of Plasmodium knowlesi versus Plasmodium falciparum in the rhesus liver: implications for malaria vaccine studies in rhesus models

open access: yesMalaria Journal, 2020
Background Rhesus macaques are valuable pre-clinical models for malaria vaccine development. The Plasmodium knowlesi/rhesus and Plasmodium falciparum/rhesus models are two established platforms for malaria vaccine testing, and both have previously been ...

18S rRNA: A Tale of the Tail [PDF]

open access: yesJournal of Molecular Biology, 2011
More than 40 years ago, the Nomura group seduced the ribosome community with the breath-takingly simple reconstitution of the 30S ribosomal subunit from its component RNA and proteins (1). However, as with many seductions, the morning-after reality is sobering.

Characterization of the TMV encapsidatlon initiation site on 18S rRNA [PDF]

open access: yesNucleic Acids Research, 1988
Tobacco Mosaic Virus capsid protein oligomers react with and encapsidate 18S rRNA from both plant and mammalian sources in vitro. The site (ei) in 18S rRNA which reacts with capsid protein to initiate the packaging reaction has been localized and partially characterized by testing the ability of transcripts from different regions of a cloned Cucurbita ...

Plasmodium 18S rRNA of intravenously administered sporozoites does not persist in peripheral blood

open access: yesMalaria Journal, 2018
Background Plasmodium 18S rRNA is a biomarker used to monitor blood-stage infections in malaria clinical trials. Plasmodium sporozoites also express this biomarker, and there is conflicting evidence about how long sporozoite-derived 18S rRNA persists in ...

Optimal eukaryotic 18S and universal 16S/18S ribosomal RNA primers and their application in a study of symbiosis.

open access: yesPLoS ONE, 2014
Eukaryotic 18S ribosomal RNA (rRNA) gene primers that feature a wide coverage are critical in detecting the composition of eukaryotic microscopic organisms in ecosystems.

Validation of a PNA Clamping Method for Reducing Host DNA Amplification and Increasing Eukaryotic Diversity in Rhizosphere Microbiome Studies

open access: yesPhytobiomes Journal, 2020
Protists and microscopic animals are important but poorly understood determinants of plant health. Plant-associated eukaryotes could be surveyed by high-throughput sequencing of 18S ribosomal RNA (rRNA) genes but the abundance of plant DNA in rhizosphere

The 18S rRNA m6A methyltransferase METTL5 promotes mouse embryonic stem cell differentiation

open access: yesEMBO Reports, 2020
RNA modifications represent a novel layer of regulation of gene expression. Functional experiments revealed that N6‐methyladenosine (m6A) on messenger RNA (mRNA) plays critical roles in cell fate determination and development.

Detection of Plasmodium simium gametocytes in non-human primates from the Brazilian Atlantic Forest

open access: yesMalaria Journal, 2023
Background Plasmodium species of non-human primates (NHP) are of great interest because they can naturally infect humans. Plasmodium simium, a parasite restricted to the Brazilian Atlantic Forest, was recently shown to cause a zoonotic outbreak in the ...

Studies on the Conformation of the 3′Terminus of 18‐S rRNA [PDF]

open access: yesEuropean Journal of Biochemistry, 1978
We have studied the conformation of the 3′ end of 18‐S RNA from human, hamster and Xenopus laevis cells. The 3′‐terminal oligonucleotide in a T1 ribonuclease digest of 18‐S RNA from HeLa cells was identified, using a standard fingerprinting method. The sequence (G)‐A‐U‐C‐A‐U‐U‐A, established by Eladari and Galibert for HeLa 18‐S rRNA, was confirmed. An
