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

Applied 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).

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

Malaria 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 ...

The nucleolar RNA methyltransferase Misu (NSun2) is required for mitotic spindle stability [PDF]

, 2009
Myc-induced SUN domain–containing protein (Misu or NSun2) is a nucleolar RNA methyltransferase important for c-Myc–induced proliferation in skin, but the mechanisms by which Misu contributes to cell cycle progression are unknown.

Upscaling the surveillance of tick-borne pathogens in the French Caribbean Islands [PDF]

, 2020
Despite the high burden of vector-borne disease in (sub)tropical areas, few information are available regarding the diversity of tick and tick-borne pathogens circulating in the Caribbean.

The human 18S rRNA m6A methyltransferase METTL5 is stabilized by TRMT112

Nucleic Acids Research, 2019
N6-methyladenosine (m6A) has recently been found abundantly on messenger RNA and shown to regulate most steps of mRNA metabolism. Several important m6A methyltransferases have been described functionally and structurally, but the enzymes responsible for ...

Free-living protozoa in two unchlorinated drinking water supplies identified by phylogenic analysis of 18S rRNA gene sequences [PDF]

, 2009
Free-living protozoan communities in water supplies may include hosts for Legionella pneumophila and other undesired bacteria and also pathogens. This study aimed at identifying free-living protozoa in two unchlorinated groundwater supplies using ...

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

Malaria 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 ...

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]

, 2012
Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

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

Phytobiomes 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
