From the Photolyases and blue light receptors belong to a
superfamily of flavoproteins that make use of blue and UVA light either
to catalyze DNA repair or to control development. We have isolated a
DNA photolyase gene (phr1) from Trichoderma
harzianum, a common soil fungus that is of interest as a
biocontrol agent against soil-borne plant pathogens and as a model for
the study of light-dependent development. The sequence of
phr1 is similar to other Class I Type I eukaryotic
photolyase genes. Low fluences of blue light rapidly induced
phr1 expression both in vegetative mycelia, which lack
photoprotective pigments, and, to a greater extent, in
conidiophores. Thus, visible light induces the development of
pigmented, resistant spores as well as the expression of
phr1, perhaps announcing in this way the imminent exposure
to the more damaging short wavelengths of sunlight. Light induction of
phr1 in non-sporulating mutants shows that a complete
sporulation pathway is not required for photoregulation. The light
requirements for photoinduction of phr1 were not altered in
dimY photoperception mutants. This suggests that
photoinduction of sporulation and of photolyase expression is distinct
in their photoreceptor system or in the transduction of the blue light signal.
