BLUE-LIGHT REGULATION IN NEUROSPORA-CRASSA

The fungus Neurospora crassa has been shown to be a paradigm for photo biological, biochemical, and genetic studies of blue light perception and signal transduction, Several different developmental and morpholog ical processes of Neurospora are regulated by blue light and can be di vided into early and late blue light responses, The characterization o f two central regulator proteins of blue light signal transduction in Neurospora crassa, WC1 and WC2, and the isolation of light-regulated g enes, indicate transcriptional control as a central step in blue light signalling.
