✦ Synopsis

During the hormonal induction of the sexual differentiation in the heterobasidiomycetous yeast, Tremella mesenterica, mating type ab cells, the notable increase in acid phosphatase (ACPase) activity was found in cell surface. Electron-microscopic observation by activity straining revealed that the increase in ACPase was specifically occurred at the surface of mating tubes of differentiated cells. The increase in ACPase on cell surface was not induced in all three-types of mating-less mutant strains, Gl-arrest-negative, mating-tube-defective and conjugation-defective strains of ab cells. Thus, it might be concluded that the characteristic arrangement of ACPase caused by sexual differentiation plays a physiological role for cell-cell recognition and/or cell-cell fusion as early events in alteration of generation from vegetative propagation to sexual one.
