FOA is a derivative of a pyrimidine precursor and is selectively toxic to yeast cells which synthesize orotidine-5’-phosphate decarboxylase. FOA has been used in a positive selection for uracil-requiring mutants(in the presence of large numbers of wild-type cells) lacking OMPdecase or OPRTase activities. This results in efficient strains for effective transformation systems.
