Light-induced absorbance changes in the fungus Verticillium-Agricinum

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

Light-induced absorbance changes were investigated in vivo in the fungus V. agaricinum (Link) Corda. There was a broad light-induced absorbance decrease in the blue and near UV with a maximum at 384 nm. An action spectrum indicated that the absorbance changes were due to photo-bleaching of a pigment with an absorption spectrum that was similar to the action spectrum. Neither redox reactions nor energy metabolism were involved in the photo-bleaching process. A direct comparison of action spectra for light-induced absorbance changes and photo-induction of carotenogenesis suggests that the photo-bleaching may not be related to photo-induction of carotenogenesis.
