abstract：:An apparent operator-constitutive mutation was discovered in the repressible acid phosphatase system in Saccharomyces cerevisiae. The site of mutation, designated PHOO, was found to be closely linked to the phoD locus. The mutant allele, PHOO, was semidominant over the wild-type allele and effective for the expression...
