✦ Synopsis

After blue-light irradiation of Neurospora crassa (wt) mycelia we observed an increase of about 13 translatable mRNA species within a period of 30 min. The induction of translatable mRNA species followed a specific temporal pattern which permitted the identification of four distinct classes. One of the translatable mRNAs was induced in less than 2 min, while the others showed lag periods of 5, 10 or 20 min from the beginning of illumination. The white collar mutants, wc-1 and wc-2, which do not display any of the blue-light-induced physiological effects tested until now were found to be defective for the photoinduction of translatable mRNAs.

Light induces the dephosphorylation of a 33 kdalton protein within 8 min in the wild-type strain of Neurospora crassa. The regulatory mutants, wc-1 and wc-2, have an altered pattern of phosphoproteins in darkness and also after irradiation. Because the wc genes have previously been implicated in pho
