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

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 ...

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 ...

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.

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 ...

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
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 ...
