    Are carotenoids the blue-light photoreceptor in the photoinduction of protoperithecia in Neurospora crassa? (1986)

    Notes: Abstract 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 at 471 nm. This is strong evidence against the hypothesis that the bulk of carotenoids are the blue-light photoreceptor for this phenomenon. However, it is impossible to exclude traces of carotenoids acting as the photoreceptor at less than 3·10-12 M in a very efficient sensory transduction chain.

    Role of nitrogen in the photoinduction of protoperithecia and carotenoids in Neurospora crassa (1987)

    Notes: Abstract Nitrogen, as KNO3 or NH4NO3, can inhibit the photoinduction of protoperithecia in Neurospora crassa when present in the medium at a high concentration but does not inhibit the photoinduction of carotenoids. The point at which the presence of high nitrogen levels is no longer inhibitory is 5 h after illumination.

    Promoter analysis of the bli-7/eas gene (1993)
    Springer
    Current genetics 24 (1993), S. 394-399 
    Details
    ISSN: 1432-0983
    Keywords: Neurospora crassa ; bli-7, eas, ccg-2 ; Promoter analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Expression of the Neurospora crassa gene bli-7, (identical with eas, and ccg-2), is induced by blue light, as well as glucose- or nitrogen-starvation. A promoter analysis was performed by an assay that does not involve promoter-reporter constructs but rather the insertion of foreign DNA into the transcribed sequence. To detect regulatory elements a series of deletions in the upstream region was generated. The inducibility of the gene, in response to the three inducing conditions mentioned, is lost by eliminating the region between-1498 bp and-1017 bp upstream of the transcription start point. A segment with an apparently negative effect was found between-595 bp and-429 bp, as well as a stretch of DNA from-429 bp to-380 bp which may exert a positive influence after light induction.

    bli-4, a gene that is rapidly induced by blue light, encodes a novel mitochondrial, short-chain alcohol dehydrogenase-like protein inNeurospora crassa (1996)
    Springer
    Molecular genetics and genomics 252 (1996), S. 223-229 
    Details
    ISSN: 1617-4623
    Keywords: Neurospora crassa ; Blue light ; Mitochondria ; Short-chain alcohol dehydrogenase

    Notes: Abstract Blue light plays an important role in developmental control throughout nature. Thebli-4 gene ofNeurospora crassa, together withbli-3, al-1 andal-2, is rapidly inducible by blue light. Induction leads to a ninety-fold increase in transcription rate over the dark control level, and the gene therefore appears to be of prime importance in the blue-light induction pathway ofN. crassa. We describe the sequencing and analysis ofbli-4 and the 38 kDa protein it encodes. We show that the protein is very rapidly imported into the mitochondria and exhibits high homology with the family of short-chain alcohol dehydrogenases.
