Abstract: | Summary Genetic analyses have been made to detect recessive suppressor mutations in eight prototrophic strains derived by treating an arginine dependent strain with hydroxylamine. The results indicate that one strain possesses a recessive suppressor, su-1, which maps outside the arg-2 locus and is capable of suppressing auxotrophy conferred by the arg-2 mutation. This suppressor is incapable of suppressing auxotrophy conferred by eight other loci. Prototrophy in the remaining seven strains resulted from either intragenic suppression, reversion, or from a suppressor mutation that is closely linked to the arg-2 locus. The results of heterokaryotic allelic tests with the seven strains indicate that the mutation to prototrophy is recessive. |
