Mating of the stichotrichous ciliate Oxytricha trifallax induces production of a class of 27 nt small RNAs derived from the parental macronucleus. [PDF]
PLoS ONE, 2012 Ciliated protozoans possess two types of nuclei; a transcriptionally silent micronucleus, which serves as the germ line nucleus, and a transcriptionally active macronucleus, which serves as the somatic nucleus.

The nuclear transport factor CSE1 drives macronuclear volume increase and macronuclear node coalescence in Stentor coeruleus [PDF]
iScience, 2023 Summary: Stentor coeruleus provides a unique opportunity to study how cells regulate nuclear shape because its macronucleus undergoes a rapid, dramatic, and developmentally regulated shape change.

A possible skeletal substructure of the macronucleus of tetrahymena [PDF]
The Journal of Cell Biology, 1980 Upon removal of chromatin from isolated macronuclei of tetrahymena, residual structures are obtained, the organization of which faithfully reflects the distinctive architecture of the macronucleus. Macronuclei are isolated by a new procedure in which cells are lysed by immersion in citric acid and Triton X-100.

The Conjusome—A Transient Organelle Linking Genome Rearrangements in the Parental and Developing Macronuclei [PDF]
Microorganisms, 2023 The conjusome plays an important role in the conjugation events that occur in Tetrahymena thermophila. The conjusome appears in the anterior of conjugant pairs during the early stages of new macronuclei (anlagen) development.

A 63-kDa Periplasmic Protein of the Endonuclear Symbiotic Bacterium Holospora obtusa Secreted to the Outside of the Bacterium during the Early Infection Process Binds Weakly to the Macronuclear DNA of the Host Paramecium caudatum [PDF]
Microorganisms, 2023 The Gram-negative bacterium Holospora obtusa is a macronucleus-specific symbiont of the ciliate Paramecium caudatum. It is known that an infection of this bacterium induces high level expressions of the host hsp60 and hsp70 genes, and the host cell ...

Phylogeny and species delimitation of ciliates in the genus Spirostomum (class Heterotrichea) using single-cell transcriptomes [PDF]
BMC Ecology and EvolutionBackground Ciliates are single-celled microbial eukaryotes that diverged from other eukaryotic lineages more than a billion years ago. The long evolutionary timespan of ciliates has led to enormous genetic and phenotypic changes, contributing ...

First Records of Two Spirostomum Ciliates (Heterotrichea: Heterotrichida: Spirostomidae) from Korea [PDF]
Animal Systematics, Evolution and Diversity, 2012 Two Spirostomum species collected from freshwater in Korea were identified as S. caudatum (Muller, 1786) and S. teres (Claparede and Lachmann, 1858). They are recorded for the first time in Korea.

Free Ribosomal RNA Genes in the Macronucleus of Tetrahymena [PDF]
Proceedings of the National Academy of Sciences, 1974 In the macronucleus of the ciliated protozoan, Tetrahymena pyriformis GL, the genes coding for 17S and 25S rRNA exist as free, extrachromosomal molecules. About 90% of the molecules are linear with a molecular weight of 12.6 × 10 6 .

Detection of Ichthyophthirius multifiliis (Ichthyophthiriidae) in two wild amphibian species [PDF]
Frontiers in Veterinary ScienceEmerging infectious diseases are one of the main threats to global amphibian populations. Frogs and salamanders are already affected by various pathogens, including ranaviruses, Batrachochytrium dendrobatidis, B. salamandrivorans, and helminths. Here, we
