Mixotrophy in Ciliates

Protist, 2010
Mixotrophy is the occurrence of phagotrophy and phototrophy in the same organism. In ciliates the intracellular phototroph can be unicellular green algae (zoochlorellae), dinoflagellates (zooxanthellae), cryptomonads or sequestered chloroplasts from ingested algae.

Ciliated craniopharyngioma

Surgical Neurology, 1985
A tumor of Rathke's cleft origin was studied, which showed some histologic features consistent with craniopharyngioma, but also had ciliated and mucin-containing cells more commonly observed in Rathke's cleft cysts. The combination of features provides further evidence that craniopharyngiomas and Rathke's cleft cysts have a common embryonic origin.

Ciliate evolution: The ribosomal phylogenies of the tetrahymenine ciliates

Journal of Molecular Evolution, 1989
We have assembled and analyzed nucleotide sequences for several different rRNA components from tetrahymenine ciliates. These include previously published and some new 5S and 5.8S rRNAs for a total of 18 species. We also report sequences for some 30 species obtained by primer extension analysis of a region near the 5' end of the 23S rRNAs (region 580 ...

Procentrioles in ciliating and ciliated cells of chick trachea

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1972
Electron microscopy of 16 to 18 day old chick tracheas revealed that procentrioles are present near the basal ends of the recently matured centrioles and basal bodies of both ciliating and ciliated cells. Cylinders 0.1 μ in outside diameter in which densely staining walls and a central axial filament can often be detected, are present between the ...

Chemical Signaling in Ciliates

Journal of Eukaryotic Microbiology, 1995
ABSTRACT. For long, our knowledge of the biology of ciliate pheromones has long relied solely upon the study of the two structurally unrelated “gamones” identified in culture filtrates of a Blepharisma species. However, the characterization of a number of polypeptide pheromones secreted by Euplotes raikovi and E. octocarinatus has now established that

Ciliate Pheromones

1996
Our understanding of the biology of ciliate pheromones, and of the primary functions of the mating-type mechanism regulated by these molecules, has given rise to radical conflicts of opinion among different investigators, as regards interpretation of phenomena, definition of basic concepts, and use of terminology.
