Evolutionary dynamics of a conserved sequence motif in the ribosomal genes of the ciliate Paramecium

open access: yesBMC Evolutionary Biology, 2010
Background In protozoa, the identification of preserved motifs by comparative genomics is often impeded by difficulties to generate reliable alignments for non-coding sequences.

Pyrimidine Dimers in the DNA of Paramecium aurelia

open access: yesBiophysical Journal, 1968
The production and fate of thymine-containing pyrimidine dimers in Paramecium aurelia DNA was investigated in three experimental series: production of dimers by UV irradiation, fate of dimers in the dark, and "loss of photoreactivability of dimers." It is shown that cyclobutyl dimers are made by UV irradiation of Paramecium DNA in vivo, that because of

Functional diversification of Paramecium Ku80 paralogs safeguards genome integrity during precise programmed DNA elimination.

open access: yesPLoS Genetics, 2020
Gene duplication and diversification drive the emergence of novel functions during evolution. Because of whole genome duplications, ciliates from the Paramecium aurelia group constitute a remarkable system to study the evolutionary fate of duplicated ...

Trade‐offs between morphology and thermal niches mediate adaptation in response to competing selective pressures

open access: yesEcology and Evolution, Volume 10, Issue 3, Page 1368-1377, February 2020., 2020
To explore how well organisms can cope with multiple simultaneous selective pressures—such as those produced by climate change—we exposed Paramecium caudatum populations to both temperature variability and predation. Our findings suggest that these two stressors produce conflicting pressures on both thermal performance and cell morphology, making ...

The mitochondrial genome sequence of the ciliate Paramecium caudatum reveals a shift in nucleotide composition and codon usage within the genus Paramecium

open access: yesBMC Genomics, 2011
Background Despite the fact that the organization of the ciliate mitochondrial genome is exceptional, only few ciliate mitochondrial genomes have been sequenced until today. All ciliate mitochondrial genomes are linear.

Effect of wortmannin and phorbol ester on Paramecium fluid-phase uptake in the presence of transferrin

open access: yesEuropean Journal of Histochemistry, 2009
The kinetics of the uptake of the fluid phase marker Lucifer Yellow (LY), and its alteration by wortmannin, an inhibitor of phosphatidylinositol-3 kinase (PI-3K), and the PKC modulators: GF 109203 X, an inhibitor, and phorbol ester, an activator was ...

Flow cytometry sorting of nuclei enables the first global characterization of Paramecium germline DNA and transposable elements

open access: yesBMC Genomics, 2017
Background DNA elimination is developmentally programmed in a wide variety of eukaryotes, including unicellular ciliates, and leads to the generation of distinct germline and somatic genomes. The ciliate Paramecium tetraurelia harbors two types of nuclei

Inhibition of the Rumen Ciliate Entodinium caudatum by Antibiotics

open access: yesFrontiers in Microbiology, 2017
Axenic cultures of free-living aerobic ciliates, such as Tetrahymena thermophila and Paramecium aurelia, have been established and routinely used in laboratory research, greatly facilitating, or enabling characterization of their metabolism, physiology ...
