Photoreceptor Pigment for Blue Light in Neurospora crassa.
Irradiating the mycelium of Neurospora crassa with moderate intensities of blue light causes a reversible photoreduction of a b-type cytochrome. The action spectrum for the photoreduction of cytochrome b is very similar to the absorption spectrum of flavin pigments. Prolonged irradiation of the mycelium with strong blue light irreversibly bleaches flavin-like pigments and as these pigments are ...
متن کاملModification of Blue Light Photoresponses by Riboflavin Analogs in Neurospora crassa.
The effect of riboflavin analogs on blue light responses in a riboflavin mutant of Neurospora crassa was studied. The analogs 1-deazariboflavin and roseoflavin, which have red-shifted absorption, acted as photoreceptors for the photosuppression and phase shifting of circadian conidiation by 540 nm light, but were ineffective as photoreceptors for the induction of carotenoid synthesis. These res...
متن کاملLight-Inducible System for Tunable Protein Expression in Neurospora crassa
Filamentous fungi are important model systems for understanding eukaryotic cellular processes, including the study of protein expression. A salient feature of fungi is the ability of the protein-processing machinery to perform all of the extensive posttranslational modifications needed in the complex world of eukaryotic organisms, making them great hosts for production of eukaryotic proteins. I...
متن کاملPhysical association of the WC-1 photoreceptor and the histone acetyltransferase NGF-1 is required for blue light signal transduction in Neurospora crassa
In Neurospora crassa and other filamentous fungi, light-dependent-specific phenomena are regulated by transcription factors WC-1 and WC-2. In addition to its transcriptional activity, WC-1 is able to directly sense light stimuli through a LOV sensor domain. Its location in the nucleus and heterodimerization with WC-2, together with the presence of a zinc-finger DNA-binding domain and an environ...
متن کاملWhite collar 2, a partner in blue-light signal transduction, controlling expression of light-regulated genes in Neurospora crassa.
A saturating genetic dissection of 'blind' mutants in Neurospora crassa has identified a total of two non-redundant loci (wc-1 and wc-2) each of which is required for blue-light perception/signal transduction. Previously, we demonstrated that WC1 is a putative zinc finger transcription factor able to bind specifically to a light-regulated promoter. Here, we present the cloning and characterizat...
