The reduction of externally added cytochrome c by Neurospora crassa conidia was observed. The reduction was stimulated by antimycin A and suppressed partially by superoxide dismutase. When conidia were treated with diethyldithiocarbamate, which inactivated endogenous superoxide dismutase, the cytochrome c reduction was stimulated. Blue light also stimulated the cytochrome c reduction. Azide, which inhibits photochemical reactions mediated by flavins, suppressed the blue light effect. Superoxide dismutase partially suppressed the cytochrome c reduction in the light. The results suggest that O2(-) participates in the cytochrome c reduction by conidia and the flavins or flavoproteins are candidates for the receptor pigment of blue light to stimulate the cytochrome c reduction. It was also suggested that the redox component(s), which could directly transfer its reducing equivalents to exogenous cytochrome c, was present at the surface of conidia.
