Modification of sporulation in yeast strains with two-spored asci (Saccharomyces, Ascomycetes)

Electron-microscope observations indicate that the single nuclear division of sporulating yeasts which form 2-spored asci resembles, in several aspects, the nuclear behaviour during sporulation of the more common 4-spored yeasts. Specifically the parental nucleolus remains behind in the ascus cytoplasm, a characteristic nucleolus-associatcd spherical structure is formed, and the nucleus divides by budding rather than by elongation and medial constriction.
