Summary
Haploid Saccharomyces yeasts showed sexual agglutination when a and α type cells were mixed. Two types of a type strains were found; one constitutive and the other inducible concerning agglutinability. In α type strains, no such differentiation was observed. Agglutination was inhibited by protease treatment. Secretion from α type cells induced agglutinability in inducible a type cells. The activity of the secreted principle was heat-stable. The secretion is thought to induce de novo synthesis of proteinous sex-specific substances or to uncover preexisting sex substances.
