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

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

Infection with the Endonuclear Symbiotic Bacterium Holospora obtusa Reversibly Alters Surface Antigen Expression of the Host Paramecium caudatum [PDF]

open access: yesMicroorganisms
It is known that the ciliate Paramecium cell surface including cilia is completely covered by high-molecular-mass GPI-anchored proteins named surface antigens (SAgs). However, their functions are not well understood.

Lipids of Paramecium

open access: yesJournal of Lipid Research, 1987
This review is the first on the composition and metabolism of Paramecium lipids. This ciliated protozoa is a useful system for studying the structure and function of biomembranes since it can be grown under chemically defined culture conditions in large ...

The Paramecium Germline Genome Provides a Niche for Intragenic Parasitic DNA: Evolutionary Dynamics of Internal Eliminated Sequences [PDF]

open access: yesPLoS Genetics, 2012
Insertions of parasitic DNA within coding sequences are usually deleterious and are generally counter-selected during evolution. Thanks to nuclear dimorphism, ciliates provide unique models to study the fate of such insertions.

The genome and comparative transcriptome of the euryhaline model ciliate Paramecium duboscqui reveal adaptations to environmental salinity [PDF]

open access: yesBMC Biology
Background As a potential model organism for studies of environmental and cell biology, Paramecium duboscqui is a special euryhaline species of Paramecium that can be found in fresh, brackish, or marine water in natural salinity ranges between 0‰ and 33‰.

Paramecium, a Model to Study Ciliary Beating and Ciliogenesis: Insights From Cutting-Edge Approaches

open access: yesFrontiers in Cell and Developmental Biology, 2022
Cilia are ubiquitous and highly conserved extensions that endow the cell with motility and sensory functions. They were present in the first eukaryotes and conserved throughout evolution (Carvalho-Santos et al., 2011).

Cryptic Diversity in Paramecium multimicronucleatum Revealed with a Polyphasic Approach

open access: yesMicroorganisms, 2022
Paramecium (Ciliophora) systematics is well studied, and about twenty morphological species have been described. The morphological species may include several genetic species.

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.

Peculiar Paramecium Hosts Fail to Establish a Stable Intracellular Relationship With Legionella pneumophila

open access: yesFrontiers in Microbiology, 2020
Legionella pneumophila, an intracellular human pathogen, establishes intracellular relationships with several protist hosts, including Paramecium caudatum. L.
