Cell surface structures in osmotically fragile mutants of Saccharomyces cerevisiae.

Abstract excerpt

Mutants of Saccharomyces cerevisiae characterized by osmotic fragility showed a marked fibrillar structure on the inner wall surface when studied by two electron microscopic techniques, i.e. freeze-etching of whole native cells and metal shadowing of isolated cell walls. The walls of the mutant cells were more permeable to macromolecules than were those of the wild-type parental strain. The synthesis and assembly...
