The formation of basal body domains in the membrane skeleton of Tetrahymena.
Differentiated regions within the membrane skeleton are described around basal bodies in the ciliary rows of Tetrahymena. These domains, approximately 1 micron in diameter, are characterized by aExpand

The Actin Gene ACT1 Is Required for Phagocytosis, Motility, and Cell Separation of Tetrahymena thermophila
ABSTRACT A previously identified Tetrahymena thermophila actin gene (C. G. Cupples and R. E. Pearlman, Proc. Natl. Acad. Sci. USA 83:5160-5164, 1986), here called ACT1, was disrupted by insertion ofExpand

Cellular polarity in ciliates: persistence of global polarity in a disorganized mutant of Tetrahymena thermophila that disrupts cytoskeletal organization.
Much of the cell surface on the ciliate Tetrahymena thermophila is covered by a polarized lattice of cytoskeletal structures that are associated with basal bodies of the ciliary rows. UniqueExpand

The assembly and positioning of cytoskeletal elements in Tetrahymena.
The oral skeleton of Tetrahymena is a precisely arranged assemblage of basal bodies, microtubule bundles and connecting filaments found associated with the feeding structure in this cell type.Expand

Identification and localization of major cortical proteins in the ciliated protozoan, Euplotes eurystomus.
Shape-preserving cortical residues have been isolated from Euplotes eurystomus cells by the application of Triton X-100 at high ionic strength. These integrated structures consist of articulatedExpand

Use of a nitrogen mustard derivative in fixation for electron microscopy and observations on the ultrastructure of Tetrahymena.
The ultrastructure of the ciliated protozoan Tetrahymena pyriformis has been studied from thin sections of cells fixed with a mixture of glutaraldehyde and tris-(1-aziridinyl) phosphine oxide. SomeExpand

Polymorphism in Tetrahymena vorax
Two types of polymorphism, differing greatly in stability characteristics, have been recognized in Tetrahymena vorax strain V2. The basic life history involves three stages: a microstome, aExpand
