Position Effect Takes Precedence Over Target Sequence in Determination of Adenine Methylation Patterns in the Nuclear Genome of a Eukaryote, \u3cem\u3eTetrahymena thermophila\u3c/em\u3e [PDF]

open access: yes, 1998
Approximately 0.8% of the adenine residues in the macronuclear DNA of the ciliated protozoan Tetrahymena thermophila are modified to N6-methyladenine. DNA methylation is site specific and the pattern of methylation is constant between clonal cell lines ...

open access: yes, 2009
This article deals with the report of two suctorian ciliates species viz. Thecacineta cothurnioides Collin, 1909 and Trematosoma rotunda (Allgén, 1952 ) as epibionts on Tricoma sp. and Pseudochromadora sp.

Uncoupling programmed DNA cleavage and repair scrambles the Paramecium somatic genome

open access: yesCell Reports
Summary: In the ciliate Paramecium, precise excision of numerous internal eliminated sequences (IESs) from the somatic genome is essential at each sexual cycle.

Transformation of \u3cem\u3eTetrahymena thermophila\u3c/em\u3e with Hypermethylated rRNA Genes [PDF]

open access: yes, 1988
The extrachromosomal rRNA genes (rDNA) of Tetrahymena thermophila contain 0.4% N6-methyladenine. C3 strain rDNA was isolated, hypermethylated in vitro, and microinjected into B strain host cells. Clonal cell lines were established, and transformants were

Morphology and 18S rDNA gene sequence of Spirostomum minus and Spirostomum teres (Ciliophora: Heterotrichea) from Rio de Janeiro, Brazil

open access: yesZoologia (Curitiba), 2013
Species of Spirostomum Ehrenberg, 1838 are widely used as model organisms in ecological studies of environmental impacts and symbioses between ciliates and human pathogenic bacteria.
