An action spectrum for photoinduced carotenogenesis in the yeast, Rhodotorula minuta, was determined over the wavelength range from 250 nm to 770 nm. The action spectrum had a prominent peak at about 280 nm, with shoulders at 340, 370 and 400 nm. In addition, at wavelengths from 260 nm to 400 nm, all slopes of fluence-response curves were approximately equal, and reciprocity was obtained at each wavelength tested. The action spectrum obtained was different from any action spectrum so far reported for photoinduced carotenogenesis and suggests that a new type of chromoprotein plays a major role as a photoreceptor.
