Detection of fungal 18S rRNA sequences in conjunction with marine nematode 18S rRNA amplicons [PDF]

Aquatic Biology, 2009
Free-living nematodes constitute an important component of estuarine and marine benthic ecosystems. Some marine and soil nematodes are known to harbor microbes, including sym- biotic bacteria and fungi, in their external cuticle as well as internally.

Towards quantitative metabarcoding of eukaryotic plankton: an approach to improve 18S rRNA gene copy number bias

Metabarcoding and Metagenomics, 2022
Plankton metabarcoding is increasingly implemented in marine ecosystem assessments and is more cost-efficient and less time-consuming than monitoring based on microscopy (morphological).

Glyphosate treatment mediates the accumulation of small discrete 5^′ and 3^′-terminal fragments of 18S rRNA in plant cells

Вавиловский журнал генетики и селекции, 2023
Under many kinds of stress, eukaryotic cells rapidly decrease the overall translation level of the majority of mRNAs. However, some molecular mechanisms of protein synthesis inhibition like phosphorylation of eukaryotic elongation factor 2 (eEF2), which ...

The METTL5-TRMT112 N6-methyladenosine methyltransferase complex regulates mRNA translation via 18S rRNA methylation

Journal of Biological Chemistry, 2022
Ribosomal RNAs (rRNAs) have long been known to carry chemical modifications, including 2′O-methylation, pseudouridylation, N6-methyladenosine (m6A), and N6,6-dimethyladenosine.

Phylogenomic Analysis of the Phylum Nematoda: Conflicts and Congruences With Morphology, 18S rRNA, and Mitogenomes

Frontiers in Ecology and Evolution, 2022
Phylogenetic relationships within many lineages of the phylum Nematoda remain unresolved, despite numerous morphology-based and molecular analyses. We performed several phylogenomic analyses using 286 published genomes and transcriptomes and 19 new ...

Genetic Diversity of Babesia canis Strains in Dogs in Lithuania

Microorganisms, 2022
Canine babesiosis is an emerging and rapidly expanding tick-borne disease in central and northeast Europe. In the last two decades, the endemic area of Babesia canis has expanded from central Europe to the Baltic region.

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

Polar 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.

Utilization of 18s ribosomal RNA LAMP for detecting Plasmodium falciparum in microscopy and rapid diagnostic test negative patients

PLoS ONE, 2022
In this study, Plasmodium falciparum was detected in patients that were declared negative for malaria microscopy and rapid diagnostic test kit (mRDT), using Plasmodium 18s rRNA loop-mediated isothermal amplification (LAMP) technique. The main aim of this

Reference Gene Selection for Expression Analyses by qRT-PCR in Dendroctonus valens

Insects, 2020
Dendroctonus valens is the main pest of the genus Pinus. To facilitate gene expression analyses, suitable reference genes for adults and mature larvae of D. valens under different temperature conditions were determined.

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

BMC 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 ...
