The influence of Congo red on the cell wall and (1 → 3)-β-d-glucan microfibril biogenesis in Saccharomyces cerevisiae
Marie Kopecká,Miroslav Gabriel +1 more
TL;DR: The effects of Congo red on growth and the wall structure in normal cells and regenerating protoplasts in solid medium can be explained by the presence of a complex which the dye forms with (helical) chain parts of the glucan network and which results in a loss of rigidity by a blocked lateral interaction between the helices.
Journal ArticleDOI
Demonstration of a fibrillar component in the cell wall of the yeast saccharomyces cerevisiae and its chemical nature
TL;DR: The ultrastructure of isolated cell walls of Saccharomyces cerevisiae from the log and stationary phases of growth was studied after treatment with the following enzymes and it can be concluded that this fibrillar component is composed of β-(1 → 3)-linked glucan.
Journal ArticleDOI
On the nature and formation of the fibrillar nets produced by protoplasts of Saccharomyces cerevisiae in liquid media: an electronmicroscopic, X-ray diffraction and chemical study.
D. R. Kreger,Marie Kopecká +1 more
TL;DR: The features of the glucan and chitin of the protoplast nets indicate that enzymes active in normal wall formation were differentially removed or inactivated by the liquid medium.
Journal ArticleDOI
Ultrastructure of the cell wall of Schizosaccharomyces pombe following treatment with various glucanases.
TL;DR: The ultrastructure of isolated cell walls of Schizosaccharomyces pombe was studied by electron microscopy after treatment with the following purified enzymes, suggesting that they were composed of -beta-(1-->3)-linked glucan and alpha-(1 -->3)- linked glucan.
Journal ArticleDOI
Disruption of the actin cytoskeleton in budding yeast results in formation of an aberrant cell wall.
Miroslav Gabriel,Marie Kopecká +1 more
TL;DR: A temperature-sensitive, conditionally lethal actin mutant of Saccharomyces cerevisiae, DBY 1693, was used to study dysfunction of the actin cytoskeleton in the morphogenesis of the cell wall and the formation of an aberrant wall over the whole surface of the isodiametrically-growing cell.
