ad-3B	IR. Between ad-3A (0.1 to 0.7%) and nic-2 (3%) (271). (482) Uses adenine or hypoxanthine (682). Blocked in interconversion of AIR to CAIR (348) (Fig. 8). Produces purple pigment, permitting direct visual selection (276, 682). Pigment is secreted with low concentrations of adenine (e.g., 0.1 mM), not with high concentrations (2 mM) (276, 682, 785). Pigment production used to assess effect of histidine and tryptophan on purine nucleotide synthesis (786). Reduced interallelic fertility (264, 407). Complementation maps (268, 274). Relation of mutagens to complementation patterns (269). Mutants with non-polarized complementation patterns on the right side of the complementation map grow on minimal medium if supplied with CO2; other mutants do not respond to CO2, (270). Used extensively for mutagenesis (see ad-3A). Rearrangement T(I- >III)Y112M4i ad-3B, which has a breakpoint inseparable from ad-3B, was the first insertional translocation to be reported for fungi (266). Allele 7-017-0137 shows "fixed instability," mutating to an unstable prototrophic allele (41). Alleles 2-17-126, 12-21-28, and numerous others are supersuppressible (408, 749, 955). Called complementation group B.	IR	B
arg-3	Uses citrulline or arginine.	IL	B
