Abstract
IT has recently been reported by Takeichi1 that the effect of ultra-violet light in inducing somatic segregation in heterozygous diploids of Aspergillus sojae is not altered by subsequent exposure of the irradiated conidia to visible light. As with other micro-organisms, it was found that the viability of the ultra-violet irradiated conidia was significantly increased by the visible light treatment, and it was therefore concluded that the effect of ultra-violet light in inactivating diploid conidia may be distinct from that which induces somatic segregation. This result is not the same as that found in a similar experiment with a heterozygous diploid of Ustilago maydis.
