A new 18S rRNA phylogeny of uncultured predacious fungi (Zoopagales) [PDF]
Mycologia, 2019 Previous molecular phylogenetic studies have shown that families in Zoopagales are not monophyletic. To test the monophyly of genera and species in the order, we used a single-cell approach to generate nuclear 18S rRNA (18S) sequences for 10 isolates representing nine taxa.

Novel insights into the genetic diversity of Balantidium and Balantidium-like cyst-forming ciliates [PDF]
, 2013 Balantidiasis is considered a neglected zoonotic disease with pigs serving as reservoir hosts. However, Balantidium coli has been recorded in many other mammalian species, including primates. Here, we evaluated the genetic diversity of B.

ESF1 is required for 18S rRNA synthesis in Saccharomyces cerevisiae [PDF]
Nucleic Acids Research, 2004 We report that Esf1p (Ydr365cp), an essential, evolutionarily conserved nucleolar protein, is required for the biogenesis of 18S rRNA in Saccharomyces cerevisiae. Depletion of Esf1p resulted in delayed processing of 35S precursor and a striking loss of 18S rRNA.

FEBS Open Bio, EarlyView.Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe
FEBS Open Bio, EarlyView.Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

Parasites and blood-meal hosts of the tsetse fly in Tanzania: a metagenomics study
Parasites & Vectors, 2022 Background Tsetse flies can transmit various Trypanosoma spp. that cause trypanosomiasis in humans, wild animals, and domestic animals. Amplicon deep sequencing of the 12S ribosomal RNA (rRNA) gene can be used to detect mammalian tsetse hosts, and the ...

c-Myc induced changes in higher order rDNA structure accompany growth factor stimulation of quiescent cells [PDF]
, 2007 Human c-Myc is believed to be a high level coordinator of protein synthesis capacity and cell growth rate, capable of activating transcription by all three nuclear RNA Polymerases.
