3 purine analogs were tested for their mutagenic activities in the ad-3 forward-mutation test in heterokaryon 12 (H-12) of Neurospora crassa. In growing cultures of H-12, the N-hydroxylaminopurines 2-amino-6-N-hydroxylaminopurine (AHA) and 6-N-hydroxylaminopurine (HAP) are potent and strong mutagens, respectively, whereas 2-aminopurine (AP) is a weak mutagen. AHA and HAP are about equally mutagenic at low doses, but AHA is more mutagenic than HAP at high doses. Despite their potent mutagenicity in growing cultures, AHA and HAP are not mutagenic in nongrowing conidia under the conditions of our experiments. AHA is the most potent mutagen tested in the ad-3 forward-mutation test in N. crassa. At the highest dose tested (30 micrograms/ml), it gave an ad-3 mutant frequency of 0.7 X 10(-2), about a 12,000-fold increase over the average spontaneous ad-3 mutant frequency. The potent mutagenicity of AHA may make it (and possibly HAP) especially useful for obtaining specific-locus mutations in other organisms.
