Abstract

The genetical analysis, by protoplast fusion, of the sterile strain ED22 of is described. Two major mutations are harboured by this strain. One, 25·22, is conditionally defective in mitosis. The other mutation, 1·1, causes sterility in strains of , or 2·102 mating-type. Sterility is due to the failure of cell agglutination. We present evidence that 1·1 is defective in the production of a non-diffusible and non-mating-type specific factor. 1 and 25 both map on chromosome I and are loosely linked.
