The bli regulon - a network of blue light inducible genes of N. crassa

Several physiological responses of N. crassa are observed when this fungus is exposed to blue light. Here, we do not intend to make a comprehensive list of all the light effects observed so far in N. crassa (for a review, see Degli Innocenti and Russo 1984. In Blue Light Effects in Biological Systems ed. H. Senger, Springer-Verlag. pp 213-219.), but point out only the underlying themes. First, the time interval between the light stimulus and the observed response can be very different, and ranges from a few minutes to several hours - or even days - depending on the nature of the physiological response in question
