Light-induced linear dichroism in photoreversibly photocromic sensor pigments 6. Relation between the 2 pigments of the mycochrome system in Alternaria-Chichorii

Summary, in English

Conidiation in A. cichorii Nattras is reversibly stimulated by near UV radiation (NUV .apprx. 313 nm) and inhibited by blue light (.apprx. 450 nm) and apparently is a mycochrome-mediated process. After induction with plane-polarized NUV, blue light polarized perpendicularly to the NUV was more effective in counteracting the induction than was blue light polarized parallel to the NUV. Both the blue-absorbing component (presumably a flavo-protein) and the PNUV (NUV absorbing moiety) of the mycochrome system are membrane-bound. The transition moment associated with blue light absorption in the presumed flavoprotein forms an angle of at least 53.degree. with the transition moment associated with NUV absorption in PNUV.
