Are carotenoids the blue-light photoreceptor in the photoinduction of protoperithecia in Neurospora crassa?

A triple albino mutant of Neurospora crassa with a measured content of carotenoids absorbing at 470 nm less than 0.5% of that of the wild type (calculated value less than 8·10-4%) had the same threshold for photoinduction of protoperithecia as the wild type when illuminated with monochromatic light...
