Limited Mutation-Rate Variation Within the Paramecium aurelia Species Complex [PDF]

open access: goldG3: Genes, Genomes, Genetics, 2018
Mutation is one of the most fundamental evolutionary forces. Studying variation in the mutation rate within and among closely-related species can help reveal mechanisms of genome divergence, but such variation is unstudied in the vast majority of ...

Evolutionary Plasticity of Mating-Type Determination Mechanisms in Paramecium aurelia Sibling Species. [PDF]

open access: goldGenome Biol Evol, 2021
The Paramecium aurelia complex, a group of morphologically similar but sexually incompatible sibling species, is a unique example of the evolutionary plasticity of mating-type systems. Each species has two mating types, O (Odd) and E (Even).

The Rab7 subfamily across Paramecium aurelia species; evidence of high conservation in sequence and function. [PDF]

open access: hybridSmall GTPases, 2020
We examined sequence conservation and signatures of selection in Rab7 proteins across 11 Paramecium aurelia species, and determined the localization patterns of two P. tetraurelia Rab7 paralogs when expressed as GFP fusions in live cells.

Massive colonization of protein-coding exons by selfish genetic elements in Paramecium germline genomes [PDF]

open access: yesPLoS Biology, 2021
Ciliates are unicellular eukaryotes with both a germline genome and a somatic genome in the same cytoplasm. The somatic macronucleus (MAC), responsible for gene expression, is not sexually transmitted but develops from a copy of the germline micronucleus

Uptake of plastic microbeads by ciliate Paramecium aurelia [PDF]

open access: diamond, 2020
Microplastics (MPs) are small fraction of plastics that are less than 5 mm in length. They are bountiful and widespread pollutants in the aquatic environment.

Paramecium Diversity and a New Member of the Paramecium aurelia Species Complex Described from Mexico

open access: yesDiversity, 2020
Paramecium (Ciliophora) is an ideal model organism to study the biogeography of protists. However, many regions of the world, such as Central America, are still neglected in understanding Paramecium diversity.

Species-Specific Duplication of Surface Antigen Genes in Paramecium [PDF]

open access: yesMicroorganisms, 2022
Paramecium is a free-living ciliate that undergoes antigenic variation and still the functions of these variable surface antigen coats in this non-pathogenic ciliate remain elusive.

New Stands of the Paramecium aurelia spp. Complex (Protista, Oligohymenophorea) in Ethiopia, Madagascar, Taiwan, and Romania

open access: hybridFolia Biologica, 2018
Knowledge about the occurrence and distribution of species from the Paramecium aurelia complex is important for understanding their evolution. However, sampling of paramecia in the southern hemisphere, and, in general, in the tropics was usually done ...
