A Transmissible developmental block in Tetrahymena thermophila

Experimental Cell Research, 1985
When the amicronucleate mutant BI3840 of Tetrahymena thermophila is mated with normal micronucleate cells, it receives a pronucleus from its partner but there is no further nuclear development and the conjugants separate, retaining their original macronuclei.

Autoradiographic evidence for self-fertilization in Tetrahymena thermophila

Experimental Cell Research, 1980
Abstract Conjugation in Tetrahymena thermophila consists of a sequence of nuclear events, including meiosis and reciprocal cross-fertilization, which result in biparental genetic endowment of the sexual progeny. Genetic evidence was recently provided that the normal exchange of gametic nuclei between conjugating cells can be efficiently blocked by ...

Rate of phenotypic assortment in Tetrahymena thermophila

Developmental Genetics, 1992
AbstractDuring vegetative, asexual reproduction in heterozygous Tetrahymena thermophila, the macronucleus divides amitotically to produce clonal lineages that express either one or the other allele but not both. Because such phenotypic assortment has been described for every locus studied, its mechanism has important implications concerning the ...

???????????????? ???????????????? ???? Tetrahymena thermophila

2019
Ribozymes are RNA molecules that contain a catalytic core and promote cleavage and ligation substrat RNA. Ribozymes can attain levels of rate enhancement and specificity similar to those of protein enzymes. Some protein enzymes use cofactors including metal ions to facilitate chemical reactions.

Perspectives on the Ciliated Protozoan Tetrahymena thermophila

2012
In biology, scientific discoveries are often linked to technical innovations made possible by an inspired choice of model organism. Ciliate species, especially Tetrahymena thermophila, have had historically significant roles as uniquely enabling experimental systems.

Meiotic chromosome pairing in Tetrahymena thermophila

Journal of Cell Science, 2004
During meiotic prophase in the ciliate Tetrahymena thermophila micronuclei dramatically elongate and form thread-like crescents. The arrangement of the chromosomes within the crescent as well as the timing of chromosome pairing and recombination with respect to the elongation process have been subjects of ongoing debate. Here, we addressed these issues

Histone acetylation in conjugating Tetrahymena thermophila.

The Journal of cell biology, 1989
We have monitored histone acetylation during conjugation of the ciliated protozoan Tetrahymena thermophila using antibodies against the tetraacetylated form of H4 histone (Pfeffer, U., N. Ferrari, and G. Vidali. 1986. J. Biol. Chem. 261:2496-2498).
