Haploid Saccharomyces yeasts showed sexual agglutination when a and a type cells were mixed. Two types of a type strains were found; one constitutive and the other inducible concerning agglutinability. In a type strains, no such differentiation was observed. Agglutination was inhibited by protease t
A diffusible sex-specific substance called alpha substance-I (alphaS-I) was isolated from culture filtrate of alpha type strains of the yeast Saccharomyces cerevisiae. The isolated alphaS-I, an oligopeptide, induced sexual cell agglutinability in inducible alpha type strains and enhanced the aggluti
