RESUMO
Several physiological reactions including the sexual differentiation of the ascomycete Neurospora crassa are triggered by blue light. Mutants in the white-collar genes wc-1 and wc-2 are blind for all the blue light effects tested so far. We have previously shown that blue light induces some translatable mRNAs at different times after beginning the illumination. Here we report the cDNA cloning of four genes that are induced by blue light. Induction of these transcripts is temporally ordered (lag times from 2 to 45 min). Analysis of run-on transcripts show that the increases in mRNA levels are due to de novo transcription. None of these transcripts is inducible in white-collar mutants.
