title: [Remarks on the modifications of cell wall during the sporulation of Saccharomyces cerevisiae Hansen (author's transl)].
abstract: Evolution of cell wall during sporulation was studied by means of scanning electron microscopy and by immunological techniques. Experiments were done simultaneously with a strain a/alpha able to sporulate and a strain alpha/alpha unable to sporulate. Under such conditions it was possible to clarify whether the changes observed were related to the sporulation or to the culture conditions. Cell wall structure modifications during sporulation were not obvious morphologically but have been revealed by immunological methods. During vegetative growth, antigenic sites of strains a/alpha and alpha/alpha were different. During incubation in the sporulation medium, antigenic structure of the cell wall was modified. Some antigenic sites seem to be specific of sporulation.
