Free-living ciliates as potential reservoirs for eukaryotic parasites: occurrence of a trypanosomatid in the macronucleus of Euplotes encysticus [PDF]
Parasites & Vectors, 2014 Background Flagellates of the family Trypanosomatidae are obligate endoparasites, which can be found in various hosts. Several genera infect insects and occur as monoxenous parasites especially in representatives of Diptera and Hemiptera.

Genome amplification and gene expression in the ciliate macronucleus [PDF]
Biochemical Genetics, 1972 The focus of this review is on the micronucleus and macronucleus in the ciliated protozoa and the organization and function of the DNA molecules within them. We present (1) some of the structural and functional differences which are known, (2) the genetic evidence for macronuclear units, (3) two hypotheses for the organization of the DNA molecules in ...

Quantitative predictions of random segregation models of the ciliate macronucleus [PDF]
Genetical Research, 1976 SUMMARYModels of the macronucleus inParamecium tetraureliawhich assume known levels of ploidy and random segregation of subunits smaller than a haploid set at both fission and macronuclear regeneration (MR) are not consistent with the hypothesis that senescence is due to aneuploid imbalance.

A Parasite of the Macronucleus of Vorticella
The Journal of Parasitology, 1942 In a sample of water from each of two water troughs used by horses at the Frances Simes Hastings Natural History Reservation, Monterey County, California, many specimens of Vorticella were found with the macronucleus parasitized by bacteria. By comparison with the taxonomic accounts by Noland and Finley (1931) and Kahl (1935) the species of ciliate ...

Putative actin genes in the macronucleus of Oxytricha fallax. [PDF]
Proceedings of the National Academy of Sciences, 1980 Previous work has shown that the macronuclear DNA of the hypotrichous ciliate Oxytricha fallax is arranged as short achromosomal pieces, 22 to 0.5 kilobase pairs (kb) in length. Micronuclear DNA has a typical chromosomal organization. Macronuclear DNA is derived from micronuclear DNA through a process of polytene chromosome fragmentation with a ...

Expanding the Family Tropidoatractidae: Characterization of Two New Tropidoatractus Species (Armophorea: Metopida) From South Korea Based on Morphology and Molecular Phylogeny. [PDF]
J Eukaryot MicrobiolABSTRACT While oxygen is essential for metabolic processes, many ciliate species thrive in low‐oxygen or even oxygen‐free environments. Anaerobic ciliates have adapted to a broad range of such habitats, yet have long remained understudied compared to their aerobic counterparts.

Morphology and Molecular Phylogeny of Endosymbiotic Ciliates (Peritrichia, Mobilida) of Marine Invertebrates with Descriptions of Two Novel Species Urceolaria clepsydra n. sp. and Urceolaria bratalia n. sp. [PDF]
J Eukaryot MicrobiolABSTRACT Mobilid ciliates are a morphologically distinct group of protists that form a wide range of symbiotic relationships with aquatic animals and includes three subgroups: Trichodinidae, Urceolariidae, and Polycyclidae. Trichodinids are best known for infecting fishes, whereas urceolariids infect diverse marine invertebrates.

Can Unicellular Organisms Sequester a Germline? The Yeast-Germline Hypothesis. [PDF]
BioessaysAsymmetrical inheritance of template‐DNA and copy‐DNA strands during mitosis can reduce the number of mutant cells. This requires that cells continuing to divide inherit the “immortal” template‐DNA, while their daughter cells become quiescent and inherit copy‐DNA strands.
