Abstract
The process of mating reaction of Saccharomyces cerevisiae was studied by electron microscopy. Prior to the dissolution of the part of the cell walls separating the conjugating pair of cells, the thinning of the electron transparent layer of the cell wall occurs at the part toward which the nuclei are migrating.
After the dissolution of the cell walls of the conjugating cells, the cell membranes become associated with each other, then to be broken and rejoined.
The first diploid bud emerges from about the middle of the zygote.
The morphological changes during the mating reaction are discussed in relation to the biochemical changes so far known.
