Addition of glucose to yeast ascospores, glucosegrown vegetative cells from the stationary growth-phase or acetate-grown vegetative cells from the logarithmic growthphase induces a rapid tenfold increase in the activity of trehalase. Trehalase activation is followed by a period of slow inactivation.
An investigation of the staining reactions of ascospores from 10 species of yeasts with 19 different dyes, showed that differentiation of spores from vegetative cells by staining depends on their relative permeability properties. Three possible staining mechanisms are discussed and examined for cons
